i'm not a fan of reraising here preflop out of position with a tight raiser, loose middle, etc with a hand south of JJ/QQ. this sort of thing requires above-average amounts of planning, even if it were a live game, but if you're concerned about the bad guy betting and the tight guy raising AK/AQ/ATs/KQs/etc just because the betting guy sucks and he wants to knock people out you can bet the flop for value and have a gutshot hedge to see the turn if it's raised and might even want to reraise depending on what happens and who did it. if it's 2 bets back to you after you bet, the cutoff means business. this isn't like an error bet just hoping to get gutshot odds, you do have a hand too and a potentially weird situation.

with the action going how it has here, i'd just fold. a set can still lose several ways if you hit it and you're not going to put the thumbscrews to them if you hit a 1-card gutshot having 4 to a straight on the board. maybe in the future if you see a similarly uncomfortable situation occuring you will find a bet without active premeditation.
