How had everyone at the table been playing untill now? Tight, loose? It is a $2 game so some people might just call everything.
First - I think you are in too early position to be raising with a hand like A 10... It is not a premium hand.
Second, Your raise is just 3x BB (plus 20) and it is not really enough to scare people off when they have 30 big blinds in their stacks.
Third - by the time it gets to the SB there is already $1,060 in the pot. He is getting great odds
to call the extra money. Hell, with my Stack so big against the blinds I would be calling with a huge range of hands such as 8 4 etc. K 2,
So - you can't really put him on a hand as there wansn't enough pressure pre-flop for him to fold.
The blinds are too small at this stage for you to be stealing them.
A 10 is not a great opening hand from early/ mid position.
I think it was a good fold from you. Nice try at the steal, But after his call on the turn, you could have got away from it cheaper.
Hope you did well in the tourney
