Manipulating your opponents

In No-limit Holdém an important skill is to manipulate your opponents.
If you play medium stakes No-limit in a tight game this can be your only way to win big. The big profit in No-limit often comes from your big hands and if your opponents are tight and don’t pay you off  you cant win much by tight play.

What you can do is start playing bad and provoke your opponents into loosen up their game. If you and your opponents have been playing tight for some time you can make a really big pre flop raise with a hand like 7-2 off.  Since your opponents are tight they will fold and you show them your 7-2. This is not good poker but it will probably make your opponents angry and  more willing to call your good hands in the future. The idea is to make cheap errors to manipulate your opponents into making costly ones. You can re raise pre flop with hands like 6-4 suited and if you hit you can win a very big pot and make your opponents believe you are an idiot.
If you  make plays like this your tight opponents will start by folding, but soon they realize they are being taken advantage of.  They resolve to “take a stand” by lowering their standards and starts calling or raising your bets. And when you hit a big hand you are now in a very good position to take their money.

Some players also use the chat to provoke the opponents.
I played a lot at Ladbrokes with a player who was really good at this ( Leecz000r ). He insulted all other players all the time. He did plays that  made him look like an idiot. And if he lost he accused the poker room for cheating and the opponents for being weak fish. Everybody hated him but he almost always took their money. He made the opponents lose control and play to loose. And when they did he took their money.
