150player live MTT, $20 buyin. It's level 4 and I have about double the chip average (about 5000chips). I have loose table image, showed a few crappy hands that hit, but also some solid hands. Most of the players at the table are very fishy. I think every action on this hand can be critisised, and I don't feel at all good about it.

64s MP, folded round, i limp in for 200, folded to BB (who has me covered - about 6000chips. and is pretty solid, plays with the goods, nothing fancy) who raises to 800. I'm not getting the odds but I figure i have position can easily fold if I miss, and if i flop a huge hand or huge draw, I can get a massive double up. Plus my chip stack had gone to my ego a bit (forgive me, though i'm sure everyone is guilty of that at some point....). I call.

755rainbow, villain bets 1000 into 1700 pot. I shove for 4000 or so figuring I have fold equity against AK AQ, and only i'm only 2to1 dog against overpairs.

He instacalls and turns over 77 for a flopped boat. So I'm dead.

Preflop was horrible right? Limp call with 64 terrible? I think so. The stacks weren't big enough for that kind of play, i was in the cash game zone! What about the flop? I figured, you play suited connectors and one gappers to hit flops like that, why fold them when you do? Constructive comments please.
