Stars $20 MTT: Need Advice on Resteal Equity

[mayesie]

Final 2 Tables. Villain has been opening 4xBB as his standard, has been recently active, and is 29/21 over 28 hands. I haven't seen anything unusual from him; I'd expect him to raise from the Button w/most pairs, most aces, broadway, sc, etc.

I suspect I don't have quite enough behind to shove (3.75 times the initial raise), though I think it's close.

I wanted to get feedback, as to whether my stack is large enough to resteal here. Does your decision change if the villain raises 3xBB?

Thanks In Advance!
