Very weird because he can only really have AA and AdKd and maybe 78s for value. I don't see him doing this with worse. You block AA & AK but you block 1 FD.

There are so little combos that beat you that if he has 2-3 combos of air you should already call. Do you have any reads? Without reads I don't think I fold this.

I would raise bigger OTT though.

no reads.. just sucks calling when you drawing dead sometimes

From the weird betsizes I'd guess he can have stuff like AdJd here and wouldn't fold. I think our turn raise should be more like 2.60 to get stacks in geometrically OTR assuming he calls.

I don't know why you should fold. Even if he was nitty mcnitterson and only 3-bet AK, KK, AA and then only jammed Ak and AA over your small bet. You'd have enough equity to call.

Board: Ah9h6d5d

Range 1: AA,AKs,AKo
Range 2: AKo

Equity 1: 57.792% Win 1: 15.584% Tie 1: 84.416%
Equity 2: 42.208% Win 2: 0.000% Tie 2: 84.416%

Bonus equity calc. Your hand against AA, AKs

Board: Ah9h6d5d

Range 1: AA,AKs
Range 2: AKo

Equity 1: 73.377% Win 1: 46.753% Tie 1: 53.247%
Equity 2: 26.623% Win 2: 0.000% Tie 2: 53.247%

You don't lose any money calling the jam. Even in the second scenario (which is super ridiculous given likely skill level; look at the sizings), you only lose a dollar.

raise to 3.5 ish OTT, and call if he shoves back. I'd expect to see a lot of AT AJ types of hand
