I was playing in a S&G 3 table NLH tourny. The blinds are 25-50, and the table has been tight passive. I'm in middle position and get delt KK. There is one caller to my right and I raise to 3x bb. Everyone folds except the origional caller. The flop comes down QT9 rainbow. The caller checks and I bet 200. This is a little more than 1/2 the pot. The caller calls again. The turn is an 8. He checks, I check. The river is another Q. He quickly bets 225 about 1/3 of the pot and I call. He shows KQo and takes the pot. My notes on this guy told me he was playing loose passive. Should I have raised more preflop? Should I have bet the turn? Should I have folded on the river? Before I made the call I thought what hands would I call a preflop raise of 3xbb from early position AA, KK, QQ, AKs, AK, AQs. What would a loose player call with AQo, AJs, AJo, ATo, KJs.... and so on. Here is where I think my biggest mistake was. It didn't look good but I called any way. I dont know if I played it differently if the out come would have changed given he had top pair with a good kicker. The only thing I can think of would have been to go all in when the 8 hit the flop. but because Jx made a straight I did not feel that would be such a great move. Please give me your thoughts on this hand.
