JJ stays overpair, but lot of action

[Jake (The Snake)]

i think the fact that the hand posted is so hand specific (you have AA and the PFR is a good player... not your typical party donk) is further proof that stop and go's should be used very sparingly. could you comment on the play and when/why it should be employed?

on the specific hand you posted, am I right to say that the reason hero played it that way was to disguise his hand against somebody who likely has JJ-KK? and also to keep the middle guy in...
