1) Villain is a maniac 66/47, Ive 2x seen him stack off OTF with naked top pair 100bb deep, If we were 100bb deep I would have stacked off, but given how deep we are I didnt want to 3b OTF and then get raised again by a set. Do we c/c here and try to control the size of the pot? I guess whats makes this tricky for me are the stack sizes.
2) What do you think about turn play?
