I love to play heads-up poker, simply because of the enjoyment of the mental battle that goes on between two good players. Its my favorite kind of game and suits me well because I play a fairly agressive style of poker usually. So, here are my suggestions...let us know how it goes.
will be your biggest weapon especially if you display it right away and never let up. You want to make two kinds of plays, raise or fold. If the hand is dencent enough to play, make your opponent pay to see the flop with you. Don't give anything away.
Keep your hand strength requirements in mind. I'm sure you know what hands are playable heads-up versus full-ring, but a lot of people don't and end up getting run over in a heads up match waiting for cards. During the early stages of a tournament or a full ring game, you may need a high Flush, a straight, or top set to win a hand, but in heads-up play you will be able to win many hands with bottom set, top pair-top kicker, or even Ace high. This is not to say "play Ace high like it will win ever pot," more like don't arbitrarily throw any hand away because it doesn't usually win when playing a full table. The reason for this is that you are only playing one other player. If the flop misses you, odds
are that the flop missed your opponent as well and if neither of you improves, your A-rag may be able to take down a pot. Same with top pair or even middle or botom pair, you really can't count anything out.
Another maxim I try to stick with if at all possible, is that I don't ever like to call
all my chips off in a situation, I like to be the one putting the other guy to the decision to call my
bet. The exception to this is when I'm strong and have tried to entice someone to push. In this instance I welcome the push and gladly call. This all goes back to the control part of heads-up play. Someone has to control the table and if it isn't you, it is your opponent. You want to maintain control of every second of play from the minute you sit down until the last hand is played. I hope this helps, and again, let us know how you do.
