The pot size is everything when it comes to the bet-fold line. For this to be correct we must be ahead something like 45-55% when we are called (adjusting for rake and folding a better hand which happens like never) and we are allowed to fold incorectly like never (since we must make up for the 10BB mistake by our edge the times we are called by a worse hand ).

The check call is much more forgiving if we are ever ahead in big pots and it also makes us unbluffable. The downside is of course that we miss some value from weaker hands that may call.

My money is still on the b/c
