How do u develop a good post flop play skill?? I just saw couple of pro's video, and they get paid off big time with their hand in the tournament and build a huge stack. I really feel that post flop play and getting paid off with a made hand at a right time are very important. I am a tournament player,and most of the tournaments I play are not deep stack so I can say I make decision mostly before the flop especially deep in the tournament. I remember I heard something that playing cash game is a good way to start?
Post things like this in Beginner's, or one of the MTT Strat forums if you can be a little more specific with your questions. Also, and I know I've suggested this before, but read the various forum stickies and FAQs first. There's a TON of stuff there that can help you.
I agree with Gonso that this question is too general. If we extract the poker theory aspect, there are two main differences between preflop and postflop play.
Preflop, you're playing for a gamble. That is, if you play well, you end up in a situation where you have positive EV, say a 60% chance of winning with $1,000 in the pot, of which you contributed $400. If you play badly, you might end up in the same situation with a 20% chance of winning. So it's like a game where the prizes are lottery tickets, some overpriced and some underpriced.
Postflop, it's very often true that one hand or another is a strong favorite. Now the game is to know when you are the favorite and get as much money into the pot as possible; and to know when you are the underdog and either induce a fold or fold yourself.
The other difference is preflop there's only a little you care to know about other players' hands. There might be five categories of hands relative to yours, a few you lose to more than 2/3's of the time, more for which you are a 34% to 45% underdog, some that you are 45% to 55%, some that you are 55% to 66% and a few you dominate. Most likely the other players don't know which of these hands they have, unless they're playing AA or 72o or something extreme. So the game is mostly about probabilities, not psychology.
Once the flop is dealt, some hands rise greatly in value while others fall. Preflop, any hand with two suited cards between T and K is pretty much the same. After the flop, the precise ranks and the suit can make all the difference. Suddenly there are dozens of relevant categories of hand, and players know which ones they hold. Probabilities are relatively minor considerations, psychology comes to the fore.
Probabilites can be taught, and there are only a few pre-flop situations which you can memorize with little trouble. Post-flop play is difficult to teach, and the possibilities are infinite. I don't know of any quick path to getting better. Play a lot, think hard and honestly about your play, keep careful track of results and read a lot. I think a large part of post-flop skill is either genetic or learned so young it might as well be. A novice poker natural will lose to a mathematician with no feel for the game in the preflop play, but will win postflop.
