Villian LanderD 26/23 he probably 3bets here around 20%, 3bets 14% overall.
Yesterday he 5b shoved me in sb vs bb over a small 4b with 56o.
Also saw him bluff4betting very tight 3bettors with 45o.
He 3bets me a ton, i play 30/25 with high AtS...
He is probably somewhat decent pre but i don't he balances his ranges well at all.
I don't fold that much to his 3bets but he doesn't seem to care.

I usually 4bet small and call it off or fold but i saw him 5betting light a lot, so i thought shoving might be better.... Thoughts?
I definitly do this sometimes with TT+,AK so there's no reason for him to snap AJ or 99. He might obviously view this different. What do you think about his calling range?

haven't played with him recently enough to be confident about his calling range but i estimated {99+,AQ+} and did some math gruntwork for you because i was bored. assuming his range is the previous, he needs to fold 75.1% of the time for this to be a profitable shove. {99+,AQ+} is the top 5.1% of hands, so if you think he is reraising at least 20.5% of his hands here your play is +EV. for reference (though it's not too applicable as he's probably polarizing his 3b range) the top 20.% of hands is {66+,A4s+,K8s+,Q9s+,J9s+,T9s,A9o+,KTo+,QTo+,JTo}

20% seems pretty nuts as a 3bet% out of the blinds against a btn raise, but again, dont know too much about LanderD in particular. i kinda doubt this is the best play though. i don't mind a call tbh


EDIT: oh lol didn't even see that you already estimated his 3b% in this particular spot. i mean if your guess is spot on, shoving here is almost exactly a neutral EV play.

dunno if its smart to sit at that table if he is gonna have position and pound on you a ton. I don't mind flatting and raising flops or floating, but since you guys have history, id rather 4bet than just shove cause i don't think he would expect you to shove anything like TT+, AK here.

I'd probably prefer to flat and see a flop with a lot of stuff, as he is really quite bad postflop.
