WTF is his hand range in this spot

[Tickner]

100bb stacks 6 handed, folded to a regular in the SB that is about 25/22 preflop and is capable of making moves if he suspects its profitable.

SB raises to 4bb, you have K[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/spade.gif[/img] and repop to $12, he calls.

Pot: $24

He checks on a Q[img]/images/graemlins/diamond.gif[/img] 2[img]/images/graemlins/club.gif[/img] 2[img]/images/graemlins/spade.gif[/img] board and you bet $17, and he quickly raises to $50.

Whats his hand range?
