50NL 100BB effective in both hands.

Hand 1:

I'm in the BB with :Ah::Kh:.
Folded round to a Poker Forum TAG who makes it 2 to go on the button, and another Poker Forum TAG makes it $6.75.

I fold.



Hand 2: I'm in the SB with :As::Kd:

Unknown scandinavian called crazySWE limps
Folds round to a Poker Forum TAG who raises to 2 on the button.
I threebet to 7.
crazySWE minfourbets to 12.

Call? Shove? Fold?

Also, do I call with the intention of folding everything but nut draws, or call with the intention of stacking off on A or K-high flops?
