1. Is the PF call ok, or should I chuck it even with 7.3:1 odds?

2. Flop cold call weak? I'm thinking a raise may have been better here.

3. Good play on the turn, or stupid raise?

1. fine, but I will often raise here. Good chance to pick up the dead money or isolate the maniac.
2. a 'cold call' is calling two bets, but your 'flat call' i sweak - I'll raise this up to $18, and this pot commits you, so you are pushing any turn. If he folds, great; if he calls, there is a good chance you are ahead.
3. As you played the flop: I like it. I think you have boatloads of fold equity, and the LAP you describe will call with less than TP3K. if you are beat, no worries, reload and stack him back in the next hour or so.
