NL200 LIVE 

Villain 1 SB - 100 USD   - Total fish

Villain 2 UTG - 450 USD - Solid aggressive plyr with moves

Hero Cutoff - 300 USD

Utg opens to 8, I call with 22ds and SB calls, BB folds. 

Flop 722hhd

SB bets 10, UTG calls I call. 

Turn 4h

All check

River 7d

SB bets 15, UTG raises to 55

Thoughts on my bet sizing (to re-raise)? I've got 277, SB has 77, UTG covers me...
