thanks everyone for the the advice. played last night and got pocket kings in late position and as usual had a lot of limpers in front of me. early in the tourny so the blinds were only 15/30. I raised 150 trying to isolate and got 2 callers. one in the small blind and one of the limpers. flop come 477 rainbow. Small blind checks then limper/caller jams the flop and I'm thinking if he's limped/called - he's either on a small pocket pair or A rags. So I call and the small blind folds. the limper turns over A5 off. Thought I was good until the river and of course the the big A hits the rivers. Guess I'm just running bad.
