I am dealt 78o on the BB. It is folded to the SB who completes. I check.

FLOP. $1. 7 - 3 - 8 with two diamonds. SB checks and I bet $1, SB minraises and I 3bet to $6, SB 4bet to $16, Hero?


Could he be playing this hand so strongly with an overpair? No reads. I had only one orbit on the table.

I fixed the post. I was on the BB and villan on SB.

something isn't right

did you raise on the button or check and the sb completed? the action is mixed up here

This is a blind battle I take it, he's in the BB not OTB.

Since it's a blind battle, I push. If he has 33 77 or 88 that's fine. His range is huge and includes overpairs, pair-and-draws, and other semibluffs (two diamonds, T9, 96, etc.).
