Here's the next hand I'd like comments on. Same general question: too aggressive? Comments?

PokerStars No-Limit Hold'em Tourney, Big Blind is t150 (3 handed) from (Format: FlopTurnRiver)

SB (t3835)
BB (t5465)
Hero (t4200)

Preflop: Hero is Button with T, A.
Hero raises to t450, SB raises to t1500, 1 fold, Hero raises to t4200, SB calls t2335 (All-In).

Flop: (t8185) J, 4, A (2 players, 1 all-in)

Turn: (t8185) 2 (2 players, 1 all-in)

River: (t8185) 4 (2 players, 1 all-in)

Final Pot: t8185

Results in white below:
SB has Jc Ac (two pair, aces and jacks).
Hero has Ts Ad (two pair, aces and fours).
Outcome: SB wins t7820. Hero wins t365.

Serious re-raise+no fold equity here and I want a pair or AK at the very least, and probably AQ to keep going here. You're very deep stacked relative to the average SnG 3-handed and it saves you from having to take this hit.
