Bankroll Considerations for the Professional and Semi-Professional II

Print
Share this
Now, let's put the foregoing to use in constructing a bankroll plan. How should you proceed? First, you should begin by determining your own salary or wage. If you are playing indefinitely, then you'll need a yearly amount you want to earn. If you are playing for only a few months, then set a total for those months. For example, you might set a yearly goal of $30K.

Second, you will need to determine how many hours per day or per week you want to spend playing poker. Let's say you want to spend 30 hours per week. You will also need to determine how many hours you need to play per day in order to achieve your income goal. You do this by extrapolating from your win rate. So, let's say your table win rate is $20/hr and you plan to pay yourself $15/hr. At that pay rate you will need to put in 2000 hours over the course of the year, or 38.46 hours per week. Hopefully the two match up or you have a nice surplus, but in our example, you have a shortage.

In this case, you'll need to make some difficult choices. You may need to play more hours or pay yourself more to achieve your income goal, but each of these choices brings costs. Perhaps you would like to spend more of your time away from the tables. You may have to sacrifice these other goals. If you pay yourself more, this will stress your bankroll and/or require a much higher bankroll to move up to the next level

This brings us to step number three. Determine bankroll needed on each bankroll requirement model. Do you have 300BBs for limit or 2000bbs for no limit? Can you buy-in for only 5% of your roll? Is your risk of ruin 1% or less with your current bankroll?

I strongly recommend using the risk of ruin formula as the dominating requirement here. If it disagrees with the other two, so much the worse for those two. Risk of ruin is far more accurate. If, however, your bankroll meets risk of ruin and the other two, this should only add to your psychological comfort. Finally, write out table win rate, effective win rate, hours you will have to play on a daily basis, and required bankrolls; have a long hard look at those numbers and a long hard look in the mirror when you ask yourself if this is really possible. If you determine that it is, then you are ready to start playing professionally. This is all still a bit abstract, so let's examine a couple of examples, which will demonstrate the process and the principles involved.

Example 1: Aspiring youngster seeks to play poker for summer job. Her expenses over the summer will total somewhere around $4000 (or $1250 per month). She has been playing online limit hold'em exclusively and is currently playing 2/4 with a bankroll of $1400. She would like to pay herself $12/hr playing 30 hours a week for 12 weeks. This is a total summer income of $4320, which will cover the bills and leave a very slight amount left over for fun or unexpected expenses.

She currently makes 1BB/hr per table while four-tabling 2/4 limit, which means her total hourly win rate is $16/hr. She also, however, gets the occasional deposit bonus and is planning to start at a new site for the summer to take advantage of the promotional deposit bonus - such as the one for Full Tilt Poker over in the left hand border here at Pokerworks. Now that bonus will probably clear at about $2.70/hr per table ($10.80/hr for four tables), so in addition to the table win rate, she will also get the bonus, which will give her a total gross win rate of $26.80/hr. Small wrinkle, however, she will clear that bonus in roughly 56 hours, so she will only make this rate for the better part of two weeks. Since what we want to discover first off is the initial bankroll requirement, we can go ahead and work with the current win rate numbers. Assuming that we have enough bankroll, we can then figure the third month separately. Now, she wants to pay herself $12/hr, so her effective win rate is $14.80/hr, which she will keep in the bankroll; hence growing the bankroll. Her standard deviation is $80/hr.

Let's check the various requirements. Does she have 300BBs? Check. The Ferguson requirement is geared for no limit play, so we can ignore that one. Does she have risk of ruin of 1% or less? Glance back at the first part of the article for an explanation of this concept and the formula (if you need to):

1% Bankroll = -(80squared/2x14.80)ln(1%)
1% Bankroll = -(6400/29.60)(-4.605)
1% Bankroll = $995.68

So, another check. As she wins, this will get better, but she only has 56 hours of play before the bonus runs out. Will she have enough with the reduced win rate? Without the bonus, her effective win rate will only be $4/hr. She will then need a bankroll of $3684. She will be adding $14.80/hr to her bankroll for the first 56 hours, which will put in $828.80, but that is not enough to get to $3684 starting from only $1400. A 5% risk of ruin requires $2396.80, which still leaves her short. Conclusion, this would be very risky as a summer job. The likelihood that she will bust her bankroll is greater than 5%, or in other words, she will go bust more than one time in twenty. Couple that with the added knowledge that this is a risky gambit and a bad run of cards is likely to be psychologically devastating. She cannot solve this problem by playing more hours either. She could drop down to 1/2, but then assuming a similar win rate, she would not earn enough to cover the $12/hr she needs for expenses. Thus, this is simply not a workable plan.

One approach to solving this problem would be to move to a new site and take advantage of another deposit bonus, since this worked so well initially. Let's say that after the 56 hours at Full Tilt Poker, she signs up at Bodog for the 10% deposit bonus, which is an instant bonus. Isn't that nice? So if she takes her $2200 bankroll out and moves it to the new site, she will get $220 bonus instantly, which will inflate her bankroll to more than $2400, but this will still not be enough. She needs $3684. If instead, she withdraws this amount after clearing the bonus, she could count it as income added to her hourly rate.

Bodog has a three table max rather than the four max at Full Tilt, so her table win rate will drop to $12/hr. She can expect somewhere around $6/hr per table, however, from the bonus. This would make the total gross hourly rate $30/hr. Since she will be taking out $12/hr, her effective rate is $18/hr, but only for about 12 hours. Then she will face the same problem of lack of bankroll as before. Note that she will clear this bonus in less than a week, and will have to move quickly to another site.

Basically, she will need to continually move funds to new sites throughout the summer. If she plans ahead she may be able to set a schedule for what sites to play to pad the win rate with various bonuses. If this is possible, she can probably pull this off for the summer, but she would spend some extra time transferring funds around. I would think this would be somewhat stressful if one did this indefinitely. That stress doesn't prevent the existence of various "bonus whores" from populating the majority of online card rooms, but it seems like a difficult life.

Now, things change dramatically if she has an alternate source of income and can play poker on the side. If she gets a job that covers half of what she needs, i.e., she only needs to pay herself $6/hr from poker, then watch what happens. Her effective win rate post bonus is $10/hr, which gives us a bankroll requirement of only $1473.60. She's starting with $1400 and so will easily cover $73.60 in the first 56 hours of play. She can still play different card rooms over the summer to take advantage of bonuses, but there will be no pressure to scout out the next bonus. Note also the rather large difference here between the bankroll one needs relative to effective win rate.

Playing poker as a part-time source of income takes enormous pressure off your bankroll. This is one significant bankroll advantage that the semi-pro has over the full-time professional. Moving full-time to poker is a risky step and must be taken with extreme caution as the bankroll is not replaceable and going bust means the end of your poker career and the end of your income.

Let's consider a second example in which a long-term professional player faces a couple important decisions. The first is how to deal with significant downswings that reduce one's bankroll. The second is growing one's game and moving up to a higher blind level. We'll assume that our pro has been playing for two years but has played several years prior as an amateur and semi-professional, and so has significant data on numerous levels of play. He is currently playing four tables simultaneously at a $1/$2 blind structure in no-limit hold'em and winning $40/hr total. His standard deviation is about $180/hr. His bankroll is only $4200, as he had an unexpected car expense.

Let's begin with whether the current bankroll is adequate to his current blind level. $4200 is more than 2000bb's so it meets the conventional wisdom standard. He can buy-in at most sites for the max (100bb's or $200) and still be under Ferguson's 5% requirement. Now to compute the risk of ruin, we need to know not just the table win rate but also the effective win rate. Let's say that he is paying himself $20/hr and so his effective win rate is $20/hr. With his effective win rate and standard deviation numbers he needs a bankroll of $3730, which he has. Thus, his current bankroll meets all three standards.

What happens if he plays a couple sessions and loses three or four buy-ins? Let's say he loses $500, dropping his bankroll to $3700. What should he do now? He is only just below the 1% risk of ruin number, so this is not yet reason to panic. Let's say, however, that he hits another bad run of cards in the next session and loses another $400, dropping his bankroll to $3300. There are two numbers that he should keep in mind when deciding whether to drop down a level to protect his bankroll. The first is the 1% risk of ruin at the lower blind structure. In the past he won $25/hr at those stakes, and had a standard deviation of $90/hr. Now at $25/hr he will only have an effective win rate of $5/hr. Note that this is a compelling reason to stay at the current stakes, since the 1% risk of ruin number given these assumptions at a 50c/$1bb game is $3730. Uh oh, he is already well below that number, and note that it is the same as the number he needs at the current stakes.

Moving down in stakes will not help unless he can pay himself less of his winnings. This leads us to the second number, which is the revised effective win rate. Let's say that he can drop his pay to $15/hr and still cover the absolute necessities. Life will not be fun during this period, but it may be necessary. This will increase his effective win rate to $10/hr at the lower stakes, which yields a 1% risk of ruin figure of $1865. If he is willing, and he really better be, to tighten the belt right now at the current stakes, his new 1% risk of ruin bankroll is $2984. These new numbers should give the pro some peace of mind. He is in front of the revised bankroll number and well in front of what he would need if he were to pass it and drop to the lower blind level. He should be able to play his normal game without fearing busting his bankroll or getting trapped.


It is very easy for pros to get trapped and bust, if they do not make the necessary changes in time. Let's say that our pro didn't figure his risk of ruin and just kept playing the current stakes and paying himself the same rate, but kept running badly dropping his bankroll to $2000. At that point, he is well below even the 5% risk of ruin number, teetering right on the brink of disaster. Perhaps now he drops to the lower stakes, as conventional wisdom (2000bbs) would suggest, but with such a reduced effective win rate he cannot reduce the risk to his bankroll, even at these lower stakes. In fact, $2000 is below the 5% risk of ruin ($2427) at these lower stakes, coming in at around 8%, which is very dangerous (about the chance that someone's smaller pocket pair is going to catch a set and crack your aces when you get all-in on the flop). The pro cannot drop another level, as this would leave him unable to pay the bills, and so the pro is trapped on a sinking ship. Sometimes things work out; sometimes the aces get cracked.

This example is instructive as it indicates that one needs to figure several numbers to get a picture of what life will be like if a bankroll is threatened. You need to know your current 1% risk of ruin number for both the current level and the level below. It may be that dropping a level will not help or only help slightly. You also need to know how much of a pay cut you can withstand if things go bad so that you can also figure the revised risk of ruin numbers. This is often far more effective at preserving your bankroll's health than dropping stakes. Finally, as a matter of psychological comfort, you should protect your bankroll and leave some margin for error, so that you do not spend mental energy worrying about your fate as a poker player, particularly as you look down at a pair of aces wondering whether they will get cracked and cost you a stack that you need to cover the electric bill for the month.

Let's turn our attention to happier thoughts: moving up a level. When one considers whether to move up a level, things tend to be going well, but the bankroll also needs to be able to withstand such moves. Let's say that our pro tightens his belt and recovers his losses and progresses on up the bankroll ladder. At what point should he consider playing in the bigger game? Conventional wisdom would suggest that he wait until he has collected 2000bbs; i.e., he would need $8000 before moving up. What does the risk of ruin formula require? If he has never played at this level, he will need to estimate his win rate.

Generally speaking, one's win rate will diminish as one moves up in levels. Estimating how much to take off is difficult and can only be done by scouting out the next level and determining how much more difficult this level is than the current one. Let's say that our pro estimates his likely table win rate at $70/hr (it is $40/hr at the current level). His effective win rate would be $50/hr. His standard deviation is a reflection of his style of play and so will remain roughly the same; hence, he can simply double it when moving up to double stakes. Thus, his estimated standard deviation is $360/hr. His 1% risk of ruin number given these figures would be $5968. That number is significantly less than the conventional rule and demonstrates the overly conservative nature of that rule for a player with this particular playing style.

Now, if things go poorly at the next level, the pro needs to drop back to the current level immediately. This is mainly due to the psychological comfort that comes with playing at a level that one has done well at for an extended amount of time. Moving up a level often produces anxiety that affects one's play and produces inferior results. The professional needs to protect himself or herself from any extended bad play. The professional, then, takes shots at the next level rather than making any permanent move. When things go well, the pro continues to play at the next level. The pro should continue this approach until reaching a 1% risk of ruin figure for the next level.

In our example the pro would need to take shots until his bankroll reaches $6714. At this point, he would have a 1% risk of ruin for the $3/$6 no limit game. Note once again that this figure is far below the conventional rule or the Ferguson rule. In fact, this number is well below what these other approaches require for the $2/$4 game, which further underscores how conservative these approaches can be for players with a low variance game.

The goal of the professional is to make money. The higher the game you can play in, the greater is your ability to earn an income. Playing in a higher game brings greater flexibility to your play. You can play fewer hours and earn more than you did previously. That's almost universally a good thing. You can also play the same number of hours and earn almost twice what you did before. That's also almost universally a good thing. Therefore, moving up when you are ready is almost universally a good thing.

One might describe my approach as overly aggressive, but this judgment stems from a comparison with the conventional approach. The statistical approach based on one's risk of ruin is a sound strategy. It is tailored precisely to one's own playing style whereas the conventional rule is a one size fits all approach. Working with your risk of ruin can open up your prospects and provide you with the confidence to move up in levels far more quickly than the conventional rule would dictate, and this move up is not aggressive any more than getting your money in as a 99 to 1 favorite is aggressive. If you were to ask any player whether that were a risk worth taking, the answer would be yes. Moreover, as I described in the discussion of moving down levels, your true risk of ruin is much less provided that you are willing to make the necessary adjustments in time.

Although the conventional rule can be overly conservative, it can also be overly liberal. A loose aggressive player may be misled into moving up sooner than is advisable. For example, if such a player were playing a $1/$2 no limit game and making $64/hr but with an effective win rate of $44/hr and a standard deviation of $400/hr, the 1% risk of ruin bankroll requirements for the $1/$2 game would be $8373. The conventional rule would recommend only $4000. Thus, for the loose aggressive player, the conventional rule can massively understate necessary bankroll. If a loose aggressive player with the numbers I've assigned were to play in the $1/$2 game with only a $4000 bankroll the risk of ruin would be greater than 11%. In other words, this player would go bust more than one time in every ten. Whether your play is tight or loose, you should work with the risk of ruin numbers to get a more precise picture of what your bankroll requirements are.

If you are contemplating a move from amateur to semi-professional or professional, then you should begin by setting your income goal and working from there to determine whether you can play the necessary hours and whether you have the necessary bankroll. I have demonstrated the limitations of the conventional rule and the Ferguson rule. In their place, you should develop a more accurate approach tailored to your own style of play and particular results. This will produce an honest assessment of what is required to make the leap from amateur to professional. Similarly, the semi-professional can make a more accurate assessment of what is required to make the jump to full-time play. Finally, all players can more accurately assess their bankroll requirements for their current level, when to move down, and when to move up.
