We're gutshot, not open ended, how about Q92r (r = rainbow, three diff suits) instead of K92r?
Without pot odds
, you chase (call) for implied odds and you bet for fold equity.
For implied odds - will villain(s) pay off sufficiently (i.e., his effective stack) if you hit? With this board, if you start betting big on a K turn, it's unlikely he'll pay you off, since your straight is a little obvious - but if you're sure villain won't let go of his hand... Or, let's say you have Q9 and the flop is JT2r and the turn is an 8 - you're more likely to get paid off cuz your straight is more disguised. Your gutshot may get paid off as well, since villain may discount you calling the flop with a gutshot, but you better get paid off huge cuz your odds of hitting suck.
For fold equity - will villain fold if you bet or raise? That's villain dependent - for example, a thinking tight passive player will fold in a lot of cases to aggression w TPTK type hands, thinking there are better spots to fight for a pot. Don't bluff fish. Note that if you have significant fe, your cards and draw don't matter as much. Multiway, don't count on fe.
Note that you should combine your pot odds, implied odds, and perceived fold equity to come up w your decisions, pot odds don't tell the whole story about the correct play.
P.S. Chasing gutshots multiway, incidentally, is a good way to go broke.
