Hero 600 Stack cutoff VERY tight image. AhAxKsTs

3 limps hero raises to 15. Dont want to discourage 3-bets if I pot it will send alarms off even to the fishes. I get 3 more calls and the 3 limpers calls so we go to the flop 7 handed.

Flop: KhTh5c

4x. Another fish who likes to donk out draws or made hands puts 30 into 100 pot .The guy after him reraises to 90. The thing is I have seen him do it with a weak holding  trying to find out where he stands. But at the same time he seems drunk and just won 3 MASSIVE pots in a row with 3 sets and he played them very weirdly. Both guys covers hero.

Result: Hero Folds

My reasoning for folding are following. I do block the nut fd BUT the problem is I CANNOT just call here since all turn cards BUT KT are bad even getting an ACE. Secondly there are 4 people left to act after me. Although I doubted they had anything good some off them are bad and WONT fold 55 here at all. I dont Think the fish will CARE if I can have a nut fd blocking him. I run Equity calc on my hand vs QhJh9* and he is ahead with 60% so he will NEVER fold that. In case I am wrong and sombody did have TT or god forbid KK I am loosing quite heavily here.

After I folded I really felt like a nit and maybe this is totally wrong by me...? After all its allready 80 bb's in the pot and if I jam and all fold much +EV here... but then again maybe  calling is decent as I can jam any ''brick'' turns?
