Rarely see this kind of action on the flop at these stakes. Both villains had recently joined the table, but so far Button seemed quite loose.

fold you've got nothing else going other than a pair of 3s and really weak cf protection on your lo draw

Would you have folded to Button's initial raise?

eh.

you do know this is like 60/40 against aajk?

give them some ranges, run some numbers on twodimes. i think people are way to quick to fold nut low + gutshots when its very unlikely that their low is duplicated.

not saying its not a fold, just that i don't think you should be so quick to fold.

This was actually a big part of my thinking in this hand. Getting quartered is much, much less likely with 24 than it is with A2.

maybe I guess it would depend on BB's betting tendencies. if he was highly likely to 3 bet maybe, but prob not in the moment. If you call here after BB's reraise you are pretty much forced to call down even if the turn bricks or counterfeits you as he's only gonna have about a $1.50 left behind. So, if you wanna gamble you might as well just reraise it AI or fold IMO. did run some numbers too which I found interesting
