Hero???

Is this a good chance to make a semi-bluff and attempt to take down the pot? Or is this an easy fold due to the bet/raise?

[Gorvacofin]

Semi-bluffing is a bad idea here because there are two opponents; the action has been bet and raise, so you're unlikely to chase both opponents out of the pot. Call if you think it's unlikely CO will reraise AND you think you can win a big pot if you hit. Otherwise fold.

PF is sortve marginal, sortve short stacks. i would either shove or fold here, most likely the latter. i don't like calling a whole lot since you're not going to get paid when you hit and you're going to have to c/f a ton of turns.

I'd shove flop ... decent equity, and the ace might be a GS,so ...
