why do ppl raise -EV hands pf?? it doesnt make mathematical sense ....

[Y SAVE, NIT??]

I make 6.5BB/100 in the long run on on 200NL i see flops about 10% raise AA KK QQ JJ AK AKs AQs

at poker tracker i see that AJs A10s KQs 1010 99 88 and 77 are nice profitable hands.Maybe i should raise with them 2x or 3x too?

The main problem i see is that if i raise 4x i will end up heads up vs stronger hands instead of 3 4 limpers with weak ace and board A95 and i have 99. Plus its always easier to make 8x BB on the limped pot once you hit the set instead of
4x8 in the raised pot when you hit the set. Or if i raise 88 4x AA KK QQ reraises to 12x and i cant call but if i wouldve limped 88 and later on he raises 4x with AA KK QQ in the long run i think its profitable play to hit a set and stack AA KK or QQ.

what do you think about raising if you have position on opponents with KJs K10s QJs Q10s JQs J10s? those are nice drawing hands and im thinking about raising them too if i have position on opponents.
