I was playing in a 25/50 (pesos not US$) game in Manila (RW). The game is full of regs but the standard play is limp/call/never fold.

I am playing 100BB deep. I get KQo on the button and after a couple of limps, CO raises to 350. I decide to just flat (3 bets tend to be given to much respect and my image is that of a TAG and I expect CO will fold with worse if I raise). BB calls and everyone else folds.

Flop is JT8. BB checks, CO bets 550, I call and then BB makes is 1650. He has about 2500 behind after the bet.

CO folds so action back on me. Now I am stuck. What is my play here? Call, raise or fold?
