Effective stacks
Hero 350
Villan 550
Straddle is on for $10 hero limps in utg+1 with 77, mp raises to $35, 4 callers hero completes
Flop is j29 two spades, checks around turn is red 7, hero makes it 90$ folds to villan (villan is tourny reg and calls down very light and overplays small pairs) villan flats. Blinds release river is 2 spades. Hero checks and villan tanks then bets 300 putting hero all in.
Should I have put a feeler bet on river??
Should I call off last 220ish??
Villan is known to build a nice stack but by end of session spew it all off with mid pair or some other bizarre play. I know there is not a lot of info but what is my move on the river??
