Depends on who is in what position.

2 possible plays.

1. Player A w/ Jc is on button, flop comes and player B bets out with his overpair, Player A will now assume that Player B Has at best TPTK because if he flopped the flush he would check to entice a bet. Player A will then Raise All in believing that he has any board pair beat and his flush outs arent dead.
Player B will be faced with the massive raise and will probably fold, not wanting to gamble his entire stack.

This could be altered depending on how long the heads up match has been going {not specified}, the earlier in the match, the more likely it is that Player B will fold.

2. Player B w/o Jc is on button, flop comes and Player A bets out with his overpair and 4-flush. Sounds similiar right? This time Player B will almost invariably make a massive raise, both will wind up allin. Then we're back to percentages.


I believe there is only one correct answer
I don't believe there is ever ONLY 1 answer.
To many external variables that cant be controlled (e.g. moods).
