Early in a $50+$2.50 HU SNG

The player has an IronMan chip next to his name and 8% ROI. A few hands ago I folded TPNK on the river when the ace came and he bet a third time into me. He also c/r the flop in that hand. After he raised me on the flop I thought he had a draw so I decided to call and lead the turn if it missed.

Comments? Is donking the turn a good play here, or should my line be different?

Fold the flop. Then definitely fold the turn, shoving is baaad.

fold the flop?? his range is composed of Kx, 43, any two spades

I agree with folding the turn though because 43 got there, ace high flush draw got there

If your question is donking the turn, then don't show that he raised and you pushed. IMO.

Flop is fine unless you have some betsizing tell or something.

Turn is atrocious, just c/f the turn. Basically any competent player knows that A didn't help you and is going to play his or her hand pretty perfectly against you. Leading just makes no sense.
