[BluffTHIS!]

I did misunderstand what you meant regarding flop types, but the example you gave of K72r is a good one where you can *often* save some money with middle set when oversetted. At the lower limits, you would be less likely to fold because players play more low pairs and have uncoordinated hands with a K and a 7 in them. But at higher limits you don't have as much of a cushion of being against those types of worse hands to make up for the times you are beat. So the higher the stakes, the more you have to consider folding middle set even on a drawing board when you have no kind of draw yourself.

If someone ovesets me in no limit HE, then they are 95% of the time going to get all my money, except in situtations like an unraised pot or 2 raises in front of me on the flop. But in omaha, you don't always have to go broke with middle set. Like LA said above, this is also just playing good poker and knowing your opponents. The tighter they are the more you consider folding, and the looser and more likely to have bottom set or a ragged top 2 like K7, then the more you consider just raising and getting it all in the middle.
