Middle of a STT. Villain was a loose-passive (running at roughly 38/6) but had previously raised in the SB and called my BB push-reraise, showing AT (I had AJ that time too). Is this a bit on the reckless side, or the kind of risk worth taking in a close battle?

UTG (t2577)
Hero (MP) (t2306)

Button (t1982)
SB (t2100)
BB (t1955)

Hero's M: 12.81

Preflop: Hero is MP with A, J
UTG raises to t240, Hero raises to t2306 (All-In)

In the light of day I just realized he was UTG and I pushed over him with 4 players still to act. What the hell was I thinking?

I hate it seeing the min raise from UTG.
