well, first off i think that that flop bet is way to small. It has to be pot size or evena lil bigger IF u are gonna lead out. I think a C/R is the best way to play this hand for sure. Let the EP (PFR) bet on this flop. Which most do like 90% of the time. He woulda led for around the pot ($12.50). Then hit him with a C/R..somewhere in the neiborhood of around $36.IMO.
However, one could make an argument that a PFR may check that flop. Due to its high co-ordination. Then my friend you made the right play to lead out (just too small). So theres my .02 cents.
