ATo in BB against weak SB steal attempt

[45suited]

Multi-tabling, no read on SB. Is my play standard or reckless? Down to 6 handed. Just started Level 4 (Blinds 50-100)

4 folds
SB (t1400) raises to 200
BB (hero) (t1400) ATo re-raises all-in

Is this play just standard or would some of you call and see a flop with position?

I dont mind this play if you know SB is making a steal if this is the first time he has done this I would be a little more worried. If it is folded to me in the small blind and I have a big hand I sometimes like to make a min raise to appear weak so you just have to watch out for that.
