KQ Top pair hand early in $55 MTT

[tipperdog]

I feel as though I screwed this up fairly badly, but I'm not sure where. Comments appreciated.

Very early (level 2; blinds 10/20) in a party $55 NL MTT. The table is very loose and passive with 5-way unraised pots fairly common. The cutoff this hand is a big stack with T2,900. I am above average with T1,200 and everyone else has more or less their original T1,000 starting stack.

I am in UTG+2 with KQo. There's a limper to me and I limp (looking to see a cheap flop and hit it). There are several additional limpers and we see the flop, unraised, 5-6 way.

The flop comes K [img]/images/graemlins/club.gif[/img]T [img]/images/graemlins/heart.gif[/img]2 [img]/images/graemlins/diamond.gif[/img]. The BB leads out for T20 and the EP limper folds. I make a pot-sized raise (~120). The cutoff cold-calls and the BB folds.

The turn is the J [img]/images/graemlins/club.gif[/img], which I generally don't like. A number of possible holdings (esp. KJ), now crush me, and the possible range of hands I beat just shrunk. I did, however, just pick up a straight draw, and I still have top pair/excellent kicker. I check, villain bets exactly 1/2 pot and I call.

The river is a blank. I check, he pushes, I fold.

Bet the turn? Fold the turn? Blocking bet the river? WWYD?
