i feel like 20-33% of the time i'm up against a set and most of the time i'm up against a combo draw. the problem is some of those combo draws are freerolling me. and a full wrap with clubs is only 63/37 favourite.

if this were a little deeper i might peel for a safe turn to jam

this raise is most of my stack.

shipping, peeling, folding...anyone?

thanks for any input
