Trying a slim semi-bluff with AK

[Jocke_F]

Villain in hands plays a TAG game and seems capable of folding a hand, this is the first time I reraise him during the session, about 80 hands in. I have been playing Semi-Loose aggressive.

Party Poker No-Limit Hold'em, $ BB (6 max, 4 handed) converter

SB ($25.35)
BB ($106.35)
UTG ($212.55)
Hero ($119.40)

Preflop: Hero is Button with A[img]/images/graemlins/diamond.gif[/img], K[img]/images/graemlins/diamond.gif[/img]. SB posts a blind of $0.50.
<font color="#CC3333">UTG raises to $4</font>, <font color="#CC3333">Hero raises to $11</font>, <font color="#666666">2 folds</font>, UTG calls $7.

Flop: ($23.50) 3[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
UTG checks, <font color="#CC3333">Hero bets $15</font>, <font color="#CC3333">UTG raises to $35</font>, <font color="#CC3333">Hero bets $108.4</font> (all in)

is this terrible?, its not something I do often but once in a while i mix it up like this. How often do you think this is TT-QQ testing if I have KK AA and will fold to a push?
