Early in a $11 $20Kgtd, blinds at 50/100 villain and hero both have around the 10K starting stack. Ante was small, not sure what it was.
We see a limp UTG, Villain makes it 450 utg+1, hero makes it 2100 in MP with AKcc, CO shoves for less (around 1500) fold to Villain who calls.
Flop(5900ish) 7d9s9c - Villain checks, here bets 3200, Villain calls.
Turn 2c - check, check
River - 3d - Villain shoves $4500ish
Hero???
