Situation:

100NL short handed, $100 effective stacks.
You pick up a strong hand in the SB. It folds round to the button who raises to $4. You raise to $15, BB folds, button shoves.

Villain is a generally solid 25/15, but you haven't seen him do this often enough to put him on a precise range. There is no recent history which might make you think he is 4-betting light.

What are your minimum hands to call?
