2nd NFD, fish minraises flop, nit in the pot

SB is a total unknown, flop minraise suggests a fish though.

BTN is 11/5 over 80 hands, nothing specific to note - obv hardly seen him play a hand.

Given the paired board and the non-nut flush draw, is this a clear fold or given the tiny raise should we call and see what the nit does?

I think the fish can have 5x, Qx, KK/AA, AhXh and probably any other two hearts.

If I do make the flush, I can't say I'm gonna enjoy being this deep OOP against the nit on a paired board with the 2nd nut flush either.

I would call and draw. I think the fish min-raise is a made hand and almost never a draw. In any case you are definitely behind at this point and I'm not that interested in continuing. It would be different if SB donked instead of c/r'ing.

A min-raise is nearly always a made hand that is being raised for value, especially when it's a c/r w/ 2 people in the pot, that looks pretty strong.

The problem you have is the BU to act behind you, it might be nitty and I could be wrong but I would probably fold.

We're getting better than 5:1 on a call. I'm never folding this.

Fish has Qx or 5x, let's stack him.
