Heads up Hand at a live home MTT tourney:

Villian seems tight but has pushed all-in PF 2 times, got 2 callers and tripled up and was the underdog both times. He will also drop a hand if pushed hard enough, I have ran him off several hands already on scary flops.

Chip stacks (approx):

Villian: T20k
Hero: T40k
Blinds: 4k/8k

Hero is BB and Dealt: Ad 7s

Villian is SB and Completes.

Hero raises the min, 8k.

Villian pushes all-in.

Hero ????
