MP is 30/20, he minraises a lot. I've 3bet him twice before, both times I took the pot down preflop. The second of those hands was the hand directly before this one.

SB is a regular TAG. He likes to 3bet me a decent amount and I usually fold pretty quick. We had a hand earlier in the session where I open raised in the SB, he reraised on his BB, I 4bet and got AI and my AK sucked out on his KK.

Here's the hand,

200NL, stacks are $225. MP open minraises, I RR to $20 from the CO. Folds to SB who makes it $66. MP folds, I do what?
