please help interpret Villain's raise

[justT]

early 2nd hour of PP 20NLH tourney

I've been at the table with Villain for about 3 orbits, he's only played one hand in which a bigstack raised 3BB's from EP and Villain pushed for 12BBs with A9s. An orbit or so later Hero's in MP with TT:


<font class="small">Code:</font><hr /><pre>
Posn Stack Preflop Action

UTG 7 fold
Villain 13 Raise to 6BB
5 fold
15 fold
40 fold
Hero 8

51
SB 23
BB 27

</pre><hr />

What do you make of Villain's 6BB raise from EP when he only has a 13BB stack? What range would you put him on?
