This is so read dependent. I think we're good here a fair amount, but I don't mind folding and see if villain makes a similar play again. If he's making a big bluff and gets away with it, he's likely to pull it again on us. Then we can call and just take his money. I have seen this line when we're beat when villains (donkish, I mean this shove is donkish) don't want to deal with 2FD's and a str8 draw out and just want to get it in.
