One important tactic in
helping you play your opponent is your
position at the table relative your
opponent. For example, you want to play more
hands against poor players or maniacs;
therefore, it is to your advantage to be
sitting to their left. When they enter the
pot, you can play a few more hands. When you
are sitting to their right , you never know
when they are going to play or raise, so you
will generally have to use your same tight
starting hand criteria as normal. Another
advantage of sitting to their left is that
you can raise or re-raise to try and isolate
yourself against the poor player.
Generally it is also good to sit to the right of tight players, especially when the overall game is relatively tight. You should have more opportunities to steal the blinds. Your raises will tend to drive these opponents out of most of the pots. On the flop, you can often bet out and get these types of opponents to fold. Sometimes, however, it can be an advantage to have these types of player sitting in front of you. If they are so tight that they only bet the very premium hands, you can easily fold your borderline hands whenever they enter the pot.
There is one player who I love to play against for just this reason. He is a top player who wins a lot of money; however this player practically never check-raises or slowplays. He always bets out his strong hands; therefore, when he bets, I can easily fold unless I have a super strong hand also. On the other hand, if he checks I can try to steal the pot since I never have to worry about him check-raising. If he were sitting in my left, I would not be able to use this valuable information nearly as much since I would always have to act before him.
