Problem I think is not 3betting and then c/folding a missed flop. Assuming the flop is not A high I think we give up to much when we fold this hand vs this type of player.

However 3betting puts us in some crappy spots, mainly when we lead (after missing) and get raised or called by the loose passive. I think I'd rather 3bet something like AJo here than KQo since we have A high and w/ the raising standards of a LAG I think our hand puts up more of a fight post flop (ie I'd rather see a showdown UI w/ AJ than w/ KQ).

In conclusion, WTF, poker is hard soemtimes.
