Vil is 75/8, 17% agg, 52% f2cb, 143 hands

With two overs, I might be inclined to call against a more aggressive villain. But against a loose passive player's turn check/shove, maybe it's a fold.

I think it comes down to reads. If you know he can c/s 98xx here, then call. If he generally has rundowns like 9876, then fold.

looks like villain will have an underhouse or a better 9 i would usually bet turn bigger, but with this sizing you can b/f happily

Pretty close spot, leaning toward a fold.

Would you guys change your mind if hero had 9TQJ for instance?
(Just because it gives more outs for a overfull).

I wouldn't because my outs could well be blocked.

You have a close call if he's shoving a random non-boat 9xxx.

You need ~36.4%. The looseness of villain's preflop range is an important contributing factor as well; against 7%-35% you are doing much worse.

That might be pretty optimistic -- 9x shoves can easily be weighted more towards A9/K9, and there's no reason >0 22/66 combos can't check-jam.

It should improve your equity quite a bit.

But if you assume he's more likely to jam boatless A9-Q9 than J9-92, and that he'll sprinkle in at least a few boats, it isn't quite enough:

lol, PPT sims and 2+2's smileys don't get along.

A9xx and K9xx with four individual ranks would be clear calls against that range. >50% of OP's 9x+ (including boats) will be at least as strong as K9xx with four individual ranks.

i fold.
