Alright. Again, I agree you should not fold your bottom set the vast majority of the time. And again, it depends on reads.

You want to minimize losses in the event you are up against a higher set, and maximize winnings if you are up against an over pair. If you push with your set, you are risking losing to a higher set, and at the same time you are risking that they will fold with an overpair.

So why not do this: Overbet the pot, say 1.5x pot sized bet on the flop. See if you get called or raised all in. If you get raised all in, you have to know your player. That's all i'm saying. It's not an immediate fold or push situation. There is grey area and a whole lot to consider beyond just the fact that you flopped a set and are likely against a higher pocket pair. Just because you can play the % game and say "between JJ-AA he only has me beat with JJ" justifies going maniacal, doesnt mean it's the best play for long term profitability.

At a low limit table against a fish, you've got it made. Against a player that knows what he's doing you are in trouble if you automatically assume you've got him owned.
