Don't fold sets in SSNL unless you have an incredible read. You have 3 options(and some slight variations of the options):

1.Push flop. If they have the flush you have plenty of outs with two cards to come. 2pair, top pair+big diamond is calling here, plus a load of other crap these guys play.

2.Raise flop, push any non diamond turn unless it pairs the board(if this happens you hope they hit the 4th diamond so you can get paid big)

3.Call flop, call turn, drawing to the full. I don't recommend this.


Option 2 is by far the best. By juicing up the pot on the flop, you can force your opponent to make a huge mistake on the turn because the pot is so big he probably wont fold the Ad.

Option 1 is fun in tough games with thinking opponents, and works great in games where people like to call.
