Rivered flush meets a massive overbet push!!!!

Villain was running approx 29/15/3. His river aggression was 1.5.

I hadn't seen him push at all and he seemed fairly solid, although I was 4 tabling and so it is possible that I missed something.

Insta fold?

Would 100BB effective stacks change your decision?

Looks like he boated up and is counting on you chasing an A high flush draw. I would also fold this against this villian even if the river diamond didn't pair the board.

I think he read you well and wants to get maximum value by shoving. If he's doing some crazy bluffshove or shoving a bad hand then he sucks and you'll get him over the next few orbits.

I'd personally shave the felt it'd get into the muck so fast.
