Post Buy-in level please.

Shove flop to prevent this exact situation. My experience is that Villain almost always jams turn when he mashes out a flop potbet. You're between 52% and 55% against hands like like TT, A9, A8, etc. You crush JT and you crush lower spade draws, which will all call after this flop sizing. Against that range, where only KK+ and Ax are unfortunate hands to get shown you have plenty of equity to get it in on the flop, especially given what's already out there. I exclude sets for the most part, even though some fish turn up with them sometimes. Villain can also be a complete spazz and fold once in a blue moon after potting the flop, I've definitely seen that happen.

As played, I think you have enough equity to call against his entire range (call 1500 to win 5150 = you need 29% equity) , but it definitely sucks a lot more now.

Fold pre, it's a 4x u have 25bbs. If he's opening this way regularly then jam pre imo.

Check shove flop.

Don't like a call there without a plan for not hitting our hand on the turn, which is gonna happen most of the time. Even when we do hit we are OOP and may find it harder to get value so will more often find ourselves in this exact situation, OOP with equity that is difficult to realise. Better to get it in on the flop with fold equity and guarantee we're gonna see two cards or take it down right there.

I'm intrigued by the sizing the villain has gone for though, very large pre and on flop, how did this fit into his overall style of play? Wouldn't expect him to be nutted very often and my main concern is him having a nut flush draw. Even with those combos in his range I'm content to get it in without reads.
