Thanks for the replies guys. Genitruc I see your point here but you only talk about hitting a set to win the pot. I like Fnord's answer here, because more often than not I feel I'm also able to push KK-QQ-JJ.. out of an ace high flop, and sometimes he has AQ-AK as well and I take it down on the turn because they dont fire two barrels with air much (something that will change at 100nl++) but still...

Anyhow I see why its not an instacall preflop now, and always calling here can be spewing.
