Villain is 44/9 over 231. Villain is pretty maniacal with a whiff of a hand post flop. Three hands of significance; one, raised flop 10x and shoved turn with TPBK, two, 3bet PF and shoved turn with gut shot straight draw, and three, shoved flop with TP (TT) and a flush draw.
Villain likes to 3 bet preflop (8% IP). I have folded my opening raise several times to his 3bet.
I think this shove is pretty standard, but i tanked for an age bc i am a nitard. I have blockers to KK/AA so at worst im facing QQ. Putting him on QQ+, AQs+, AQo+ I have 51% equity plus a ton of fold equity.

I dont like flatting bc he is shoving the flop for certain.
