These small 5bets are nearly always AA, but perhaps some villains might 5bet/fold here if they have a bluff range at all. Is there any benefit to calling villain's 5bet and calling a shove or shoving OTF?

I think 5bet bluffing is so rare, especially vs EP-MP openers. Unless you have been 4bet/folding in your history vs villain. So i think it is more a question of wether he does this with AKs and QQ.

Don't think he can fold anything btw way after 5betting, so i'd just shove. Calling and jamming could be ok, but he might be able to find a fold with what you beat then, so i wouldnt do it. Basically i wouldn't worry to much about folding out a bluffing range.

stats?

Nah,sometimes they shove up with TT or AJ. If you fold and he shows you 72 u will tilt as hell

It's zoom poker. People always show up with the top of their range.

Why is this a thread?

There is no merit to calling villain's 5bet and I'm not folding. That leaves one option.

Gl folding KK to 5bets

Lol, 5B bluff range at 25NL...

Just shove. Sucks when he flips over AA - but its a joy when he has himself a badly played and overrated QQ or AK

Thats exactly what I did not mean, awesome reading comprehension you got there.

Point I was trying to make is that this is just wrong. His most likely range is QQ-AA and AK. Not some weird 5bet bluff you mention.
Watch less poker on tv.

The guy shouldnt ever be folding to a jam even if he is bluffing so just ship

If you call it's just going to let him fold QQ or AK on the flop.

Why would you ever call and then shove any flop? He either has AA only in which case he's calling anyway, or he has QQ and AK in his range. Both would have called a shove pre once they 5bet but you actually manage to get AK to fold sometimes by shoving the flop so all you would achieve is to lose value from the part of his range that you beat.

Ship it then. No need to wait for the flop, he's either got AA which you're getting called with regardless or Q-Q, A-K (as mentioned above.) A-K he can get away from on the flop and Q-Q he can too so might as well get it all in

Good point! Should've thought more before posting, but I did have follow-up questions...

From the reverse perspective, I would usually just 5-bet shove. Do you see any merit to 5betting any other amount 100bb deep? Like, is there any benefit in doing this with AA ourselves?

Standard sort of TAG, maybe a bit on the stationy side. 24/18/3.0 over 214 hands. 3betting 15.4% (13) versus CO, 6.7% OOP, 8.3% IP. He's polarized. Probably a lot to be said for flatting here. People seem very 3bet happy at Zoom, but rarely 4bet/5bet with KK+.
