$2 PLO double-board bomb pot (1/1 stakes NLHE otherwise), 8-handed

BB - ~$250 - Usually tight, has shown to overvalue mediocre hands/stack off light in PLO bomb pots
UTG - ~$300 - Biggest action player in game, will stack off very light in PLO bomb pots
LJ - ~$550 - Makes some odd plays but fairly straightforward/decent in PLO bomb pots
Hero (CO) - ~$280 - Perceived as one of tighter players in game, given a lot of credit when raising

Hero is dealt 773T

Top board 736
Bottom board Q54

Checks to CO who bets $16, Hero calls (questionable call maybe with so many in back of me? Too weak to repot?), Button+SB fold, BB re-pots, UTG re-pots, CO shoves, Hero???

Seems likely I'm up against at least one 45xx, but also have to question if I have enough live outs to continue (holding a 3, only 2 6's are clean for a straight draw on the bottom board and not a nut straight). Very possible one of the all-ins is going nuts with 33xx or 66xx as well.

Clear cut fold with so little invested? Way too nitty to just fold to the initial bet? Or should have I re-potted?

I can’t fold fast enough

This is not close at all.

You're putting in $280 to win $420 .. are you a 40% favorite with your set and blocking a FH out? And you're really only dragging in $560 .. so your equity now needs to be 50% on the top Board. It's possible ..

You do block one of each flush, but you can't count on winning with a 6 (one is dirty) on bottom with middle straight most of the time and while the 45 is shown on bottom there's a chance someone is holding it on top.

It's too late to 'image' raise .. they're already all-in!

This is why we BP .. to get the tighter Players into spots like this! GL

I would fold... Unless I hated money and wanted to donate.
