Villain 27/27 AF 2.0 over 15 hands. I decide not to cbet with the intention to x/c otf because I think the range he'll call a cbet with on this board is stronger relative to my hand than the range he'll stab with when checked to. And if he does x back it serves the purpose of pot control with our sdv hand. On the turn I delayed-cbet to get calls from draws he might have picked up here. Without enough info to know whether a villain is aggro enough to raise with a draw here do we just give him credit when he then raises? Many hands that have us in bad shape I see him play this way and we have zero info on his resteal calling range. If we call here what's our plan for the river?

SB: $2.03 (101.5 bb)

UTG: $2.01 (100.5 bb)

Hero bets $0.18, BTN raises to $0.45, Hero?

you cant call river bet,vrs unkown fold

Idk how you play, but imo you'd be hard pushed to get a higher ev from 3bing as opposed to just calling pre

xc seems very meh, I think I'd cbet for a bit of protection/value/implied with bdnfd

Folding turn seems best, but I'd probably station and lose more than I should. Either way fold imo.

ya call pre.
