Should I have folded the turn here? the warning sirens were going off that SB probably had me beat, and that button may have hit a set. Should I just fold or was I right to call down with the over pair? and if I should have folded, WHEN should have I? When he capped the flop?

I would raise the turn puttnig button on A/J [img]/images/graemlins/diamond.gif[/img] or K/J [img]/images/graemlins/diamond.gif[/img] flush draw. You have an over pair and you can't fold this in a 2/4 game

[lightw1thoutheat]

dont fold here at any point. it depends on the sb whether i put in a raise on the turn.

youre likely beaten, but i think youre good enough of the time here against some average 2/4 opposition to make this play +ev
