In his article Heads Up , Tony Bromham addresses the special circumstances involved when playing Heads Up, and suggests that aggression is the only successful style. A player simply cannot be tight and wait for the good cards to come. The consistent HU winners do not abandon pots simply because they have bad cards. To win consistently HU, you must pick up the orphan pots, when neither of you have a hand. If you do not bet or raise, you can only win by showing down the best hand. Winning HU poker can be summed up in one of two words, BET or RAISE. Everything in Poker is situational so most of these recommendations begin with "if," and that is a pretty big word. So let's take the most frequent situations and consider a plan.Situation 1 (Small "Ms")
If both of you have small stacks relative to the blinds, you don't have much room for fancy plays, even if you have the chip lead, almost every play is all-in or fold. Remember, a call all-in has no fold equity. You must have the best hand to win. On the other hand if you push all-in first, there is some fold equity and against any two cards, that fold equity is significant. You aren't betting that your hand is good. You are betting your opponent's hand is bad.
Situation 2 (Large "Ms" and the stacks are equal or you have the larger stack.)
Now you have some room to play poker and you should probably avoid big confrontations preflop, except with very good hands. Your goal should be many small pots, not big all-in confrontations. On the button; although you act first before the flop, after the flop you act after your opponent and this roll switch gives you a unique opportunity. You can push and pull at the same time. You push him out of the pot with a bet or pull him into a pot and push him out later.
The key to successful HU play is to keep him guessing what you are doing. Most poker authorities agree that, Heads Up, the pot odds of 3:1 warrant calling with any two cards from the button. It makes sense, after all you are getting the proper odds versus a random hand, but if the key element of HU is aggression, why not raise? A minimum raise seems appropriate. You are doubling the stakes when you have the advantage, and you pick up some fold equity. Of course, if you raise every hand, even the densest opponent will start playing back. So, you probably shouldn't raise more than 60% of the time. Although a call is still appropriate for the pot odds, you might consider folding the worst hands to suggest that most of your raises are somewhat warranted. (This is a different type of fold equity.) Raising more than three times in a row probably is not a good idea. Your quarry might wake up. If your opponent does play back, call small raises with good hands, re-raise with the best hands, and avoid pot sized raises unless you are willing to go all-in with this hand.
After the flop your opponent is faced with a decision; bet into a hand that raised preflop, or check. Regardless of their action, you have the initiative. If you think you have the best hand, continue to bet. If you believe your opponent will lay it down, bet. Be prepared to lay it down if he comes over the top, unless you have a great hand. If your opponent bets, few hands warrant a call. Lay it down. If the hand proceeds past the flop, you have to make your play based on the situation and you really want to have the best hand. Don't hesitate to check it down if the flop and subsequent board is a bust. (Of course if your read is good, you can always bet into an opponent that tends to fold.)
From the big blind the play is more passive, but very aggressive if the cards warrant it. Since you will be out of position after the flop, you would rather win the pot right now, before the flop. If the button simply calls, make a pot sized raise with any hand that stands to be the best hand. Check everything else and look at the flop. If the button raises, call with any good hand, raise with any hand that stands to be the best, and fold the bad hands. When you encounter an opponent that raises often from the button (as suggested above,) you should consider loosening your standards for calling and play back at him with a pot sized raise with any hand that stands to be the best hand.
After the flop you should usually bet if it hit your hand, but check raise often, even with some questionable hands. You want to deter your opponent from raising automatically when you check. If the flop misses you, give up on the hand and hope your opponent checks it down, maybe you will get lucky.
Think of it this way, pre-flop you are playing small ball, but after the flop never pass up a chance to pick up extra bases.
Situation 3 (Large Ms" and you have a significantly shorter stack than your opponent.)
In most situations it is difficult to overcome a large stack, especially against a competent player. If the cards break even, the smaller stack loses so you have to be a little more willing to gamble, and the shorter you are, the more willing you should be. Your tactics should be the same as above but the raise sizes should be different. Instead of pot sized raises, push all-in. Even from the button your initial raise should often be a push. Your small stack does not give you the luxury of playing small ball. From the button, you might call more than raise, but be prepared to push with good hands or when the flops hits your hand. From the Big Blind, if your opponent calls, be prepared to push with any hand that stands to be the best. If your opponent raises, while you are holding a good hand, call and then check raise on the flop if your hand stands to be the best hand. Hopefully the bets will trap your opponent into doubling you up with a weak hand.
Here is a quick summary:
• Ms are small: Push with any hand that stands to be the best.
• Ms are large: With the big stack or equal stacks, raise the size of the pot except preflop from the button. With the small stack, raises tend to be all-in.
From the button:
• Minimum raise then continuation bet on the flop.
• Never raise from the button more than three times in a row without premium cards.
• Be prepared to lay it down if your opponent comes over the top.
From the big blind:
• Raise, (Pot Sized,) if the button calls and you have a good hand. Check with everything else and see the flop.
• If the button raises, call "small" bets with most marginal cards, reraise with premium cards, and fold junk.
• After flop: Make a pot sized bet with good hands. Check raise with very good hands. Check and fold with most bad hands.
