Villain is 22/17 with a 75% foldto3b after 700 hands.

I think a flop check/call is standard. I think I'll have enough barrel bluff opportunities with AQ/KQ that I don't have to turn 99 into a bluff on this board.

I don't think there's much merit to betting the turn after the flop goes check-check for the same reasons I didn't bet the flop. I suppose villain could be delay cbet bluffing but the fact of the matter is that the board smacks his range and I'm unlikely to get paid on the river if I do hit. However, my range is capped to a hand like AT at best so it's a pretty decent spot to take a stab.

Simple fold?
