1K Winstar Blind Vs Blind

[Ben86]

Villian is an older man who has been playing tight and built a large stack from putting a couple coolers on two people.
I have pushed all in to steal the blinds and antes 4 times in the last 2 orbits, i think my image is pretty terrible right now.
Villain: 12K
Hero 4K
blinds 150/300 ante 25. 9 handed

folds around to villian in SB, villian completes. The last time he did this I raised he folded, so since my image was shot I thought I would just check.

Villian leads 2k. I'd seem him do this once before but the opponent folded. Hero?
