I remember at a local tournament, I crippled this one guy so bad.
Everyone folded to me (D) and I raised 3.5x BB knowing the BB was tight. But he called.
Flop came 9

BB bet the pot. I immediately put him on the King and knew he wasn't drawing to the flush and was afraid I was or he would've checked s usual to see a free card. This guy was scared of flushes all night and folded top pair once on the turn to a flush draw. He probably suspected I had a straight or flush draw. I called.
Turn: A

Crap!!! There goes my bluff I thought. For a tight player to bet the King agressively meant he probably had the A with it. I was pretty sure he had 2 pairs. As I expected, he bet almost the pot again. I called.
River: 7

Oh wow! I think like Phil Helmuth (haha) I "looked into his soul" and saw his 2 pairs crumble. I was begging for a check and got it. I had a lot more chips so I decided to put the guy all in with the usual "How much do you have left" test of will.
He thought about it; showed me the K

A

then threw it to the center of the table.
I then layed the 7

face up to his agony. I think I put him on Tilt that lasted weeks as he changed his game from tight to a more loose Gus Hansen style and actually did quite well weeks later
