So this was in the early stages of a deep stacked MTT (if that matters).
I'm on the button and two people limp in and i decide to join in to see a flop with my sixes, bb raises to 4x and we all call. Flop comes 234r. Considering the bb raised im putting him on a range which includes a lot of face cards, maybe a big pocket pair. It checks round to me and i bet half the pot, partly to see where im at and partly because i think i might have the best hand. The bb calls and so does one other guy. River comes another 3. BB checks and the other guy weirdly just bets 50, anyway i raise him to half the pot which is about 1000. The bb folds and the other guy calls, which makes me a little uneasy. The river comes a king and once again he bets 50, im a little weirded out by his bet sizing especially considering the fact he called my other raise on the turn, so i just call. He shows K2s and i lose to the two pair.
I ended up losing about 20% of my 10,000 stack and this was the first hand of the tournament so it tilted me a little bit. My question is, was i being too confident with my sixes? Should i have kept the pot small considering loads of cards could have nullified my over pair?
