Both you (SB) and unknown villain (UTG+1) have 100bb stacks. Villain raises 4bb. You have a nice hand so you raise it to 12bb and Villain calls.
Flop is: Js, Qs, 3d
Pot is 25bb and you lead for about 20bb. Villain doubles your bet and makes it 41bb to go.

What's your move for each of these starting hands:
AA
KK
AKo
JJ
