It's very funny you should say "he sounded like a poker pro before that hand".
Last week at my home game, a new player was invited by one of our regulars. He sat down at our table with Oakley sunglasses, a FullTilt hat, and kept his leather jacket on the whole time. I instantly thought "wow this guy is sure playing the part of a poker pro." He was very quiet at first, playing very very tight. About 30 minutes had gone by, and he started being a bit too vocal and blatently bluffing at small pots. Trying to drop "poker terms" like he invented them, I could tell the guy had no idea what he was doing, and had been watching way too much WSOP
An hour had gone by and now I was just "toying" with the poor guy. Pretending like I had no idea what I was doing at the table, and even asking him for advice or to clarify what he meant by "the nuts".Everyone at the table played along (even the gal that had invited him.)
I wasn't gaining chips, and I wasn't loosing them. I was playing very tight, waiting for the perfect chance to bust him. I check my hole cards (AK<>) and raise. The table folds, except for our "Pro".
He calls, and the flop gives me nut flush (2,4,10<>) I bet 4xBB expecting a quick fold. He calls.
Turn is 5C. I bet pot, he calls.
River comes down 4H.
I push , and he folds.
The "pro" flips over pocket 10's and says "F**K man, I know you have that flush, and I don't wanna loose all my money"
Everyone at the table laughs, and I say "yeah, it's a good thing you got outta that one"
His arrogance, and lack of basic poker knowledge paid me off big time!
