I have no idea how to play this game...

I'm up at the radio station right now and I just finished bubbling a $26 knockout 90 man tourney, just missing the money. It was a rollercoaster tourney where I was close to elimination a number of times, but I would estimate before I busted I pushed all in at least 25 times because the blinds got so big. :) It was funnn.

I was close to having a big stack down the stretch when I moved in with A7 and was called by K9. The flop came down 7 T x, turn is an 8, and the river brought a Jack making him a straight. I came back after that though, just unfortunate I bubbled but I did all I could.

SO the point of this is that I jump into a nickel/dime cash game right after and I somehow forget that a full house beats a flush my first hand in the big blind:

I have no problem with my flop play. But I should have bet the turn and NEVER should have bet that river. But something went off in my brain that said "I have him" and then he turned his hand over and I went WTF DO I KNOW HOW TO PLAY AT ALL???
