So it was checked down after flop. What was the end result?

I dunno 9 handed, two pair I'd think to be out of the picture, maybe trips(highly doubt it though). I'd put his raise on an AK/AQ/AJ Diamond draw or 10/10 J/J or Q/Q....not rockets though. Slim possibilty he has A/9 suited. My gut says he's raising air.

For myself, with your stack....I fold. Yes I'm getting all my chips in with a decent hand, but not the best flop to do it with.

I'd have liked to have seen a $3-4 PFR, show strength from under the gun. As for your flop bet, I'd have liked to have seen a 85-95% pot bet or check. 50% pot is a no no for myself. Atleast if you'd have checked, it possibly could've kept the flop bet lower than $47, and you could've then smoothed it or RR AI, up to you at that point.

All in all, I disagree with pre flop and flop play, but I do agree with lay down.

PS, did CO have trips and did the BB have a busted flush draw?
