Ok quite specific situation.

Villain is pretty average preflop, calling station when drawing and makes seemingly random large bluffs on late streets. On another table with him he bet 3xPot on the river with A high and was called down by a slowplayed set. Have seen him go to war with TP.

Villain is BB with $29
Hero is SB with $62

Dealt to Hero [ ]
Folded round to SB. Hero raises to $1.50, Villain calls
Pot= $3
Flop [ ]
Hero Bets $2, Villain calls At this point my hand sucks and he could have any number of draws or even one of the higher pairs
Pot = $7

Hero checks, Villain Checks. Now I think he had a draw and I just gave him a free card. Not too upset though as my hand is weak, he calls with draws, and I didnt want to build a big pot. I Now plan on check calling a river bet if a blank comes down.

Hero checks, Villain bets $10, Hero??

That bet was more than I expected to have to call. Abandon ship?
