You can't call the flop to c/f the turn here. After he raises, I can't really see an instance in which he checks back unless its with a FD, but even then, he's binking his flush almost 20% of the time on the turn and another 20% on the river when he checks back. That's giving up waaay too many chances for him to draw out on us.

Like I said, I like a flat, donkbet/fold on the turn. Yes, we commit a large portion of our stack by doing so, but we also don't get fucking raped by his entire range, only the part that beats us and we get away for a lot cheaper by doing so then by just getting it in on the flop by a range that mostly dominates us.
