Hero shoves?
Hero folds?

Axs hands are nice in that besides being against AA they have at least 30% equity, and having an A cuts the possible AA in half

there is $70 in there for the taking if he doesn't have a monster, but the raise amount felt trappy

I'm pretty loose and have a wide MP2 range in general, though I haven't played with villian much so Im not sure he knows that

Fold cause you're a pretty huge dog to his calling range and he will very rarely fold.

I'd shove AK.

Usually this is a clear fold situation with no history.

fold or shove. calling here is terrible, but I'm sure you know that.

but with no history, I fold here.

you cn get away cheap here with a note. I'd take it.

If you have a read that MP3 and CO NEVER have a hand to call with AND typically won't CC with Ax then I don't mind a shove. If they are coldcalling with Ax type hands or might slowplay JJ+ then I don't think shoving can ever be good here.

Any ideas on if btn will fold JJ or QQ and how often? Folding is probably better most of the time, but I wouldn't mind a shove here with some kind of reads.

how tight and how big is the sample?

shove if he ATSB >35% and PFR >11%

fold otherwise
