Being a lifetime chessplayer myself here is what chess brings over to poker

1. Being used to analysing the game, questioning decitions and studying the games of stronger players

2. Addapting to opponents .. When you are about to face a player first thing you ask is, what is his style, and what are his strenghts. And then you tailor your opening game and approch to him, so that you maximize the chances of him not playing his best game.


3. Desperado plays in lost situations .. you also bluff in chess

4. Using drawoffers as a psykological weapon .. and other mindgames

5. But most important .. In chess when ahead it is vital to keep applying pressure ... never give time for your opponents to relax, just keep pushing til they fall apart




But similarites between chess and poker IMO come down to The Psykology bit and being used to approching the game in a structured way while studying it. (And of course countless postmortems after playing a chessgame spills over to rethinking and reviewing your poker hands or tourneys after you have played them ... a sound thing to do, all the time questioning your own play ... always asking, where could I have played better ??)
