yeah my point was, if you cold call pf without knowing exactly why you're doing it (as goes for anything you do in poker), you're bound to spew lots and lots of money postflop. if you call a supertight villain's UTG raise with 87s, since you're not going to flop strong made hands very often (contrast with 66 which flops a set about twice as often than you flop two-pair, trips, straight or a flush with a SC) you will have to be able to play your draws aggressively and be able to steal pots away from him in order for the PF call to be breakeven or +EV.
