I have a 250 stack in a 2/4 game with a few good players but 3 very weak players.

There are 3 callers to me in the CO with 56s. I limp, btn limps, blinds check.

Flop 457r

Blinds check, a tricky/tight utg+1 player bets out 20. A weak/tight utg+2 player calls. A loose/aggro/monkeytilt player goes all-in next for 90.

Action is on me.

Fold or raise as a semi-bluff if you think that the tricky TAG player might fold. Mostly fold, you probably have the worst hand in this situation. My guess would be that the TAG player is holding an over pair or has top pair with one of your outs, and the LAG player can have anything, including made straight or set. You have to float LAGs or bet them out on drawy flops with strong hands, and avoid calling their large bets, especially shoves, with marginal hands like yours.

I think folding with this much equity is a mistake. I think I'm ok with just calling. Since you're probably drawing you don't really mind overcallers (cause if you hit you'll probably win and if you miss you'll probably lose). Stacks aren't really deep enough that you fear UTG+1 moving all in.

So, what range do you put his opponents on? I don't think he has any implied odds in this situation, and not enough equity to call. He is most likely against two better pairs, maybe a better pair and a better draw IMO. What's your thinking?

It's a small pot pre-flop ($28 minus rake). Though, the bet, call, and raise have put another $130 in the pot.

You're in fair shape against an overpair such as 99 (but still an underdog) but not that great against 87o or some other hand which takes away some of your outs. Of course, you're doing even worse against a set.

I think you're implied odds here are bad. If an 8 or 3 comes, the threat of a straight is obvious to everybody. A 5 isn't likely but could still scare others off. Even if a 6 is good, the same straight threat drives others off. If you make the straight, you may be splitting the pot.

You have three players behind you yet to speak since the blinds easily could have checked a big hand. Also, the two EPs have had the betting re-opened for them.

I tend to fold in these spots. But, that may be too conservative.

If you push, I don't think it can be too big a mistake.

The one play I don't like is calling to make a hand with no implied odds.

In practice, I probably call and hope all others call as well. If I get raised, I think I'm calling off my stack. I wouldn't raise b/c I don't want to drive the others out of the pot.

If I stopped to think about it, I would fold b/c I think I'm chopping the pot if I hit my OESD and I don't think my two-pair draw is live.
