A-10s- Top pair how is my line?

[Erik W]

Seems fine to me.
If he had a 9 or a heart draw he would like to leave all the other players in and probably would have bet out. This looks like a protection raise with a T.

I think your flop bet is great and calling SB's raise is good too. MP2 folds now your heads up with a SB who most likely would wait to C/R the turn if he flopped his set of 9's. So a turn raise would be best making him pay you with a weaker hand like JT or QT or possibly even worse. Then don't miss a bet on the river pending a fairly safe card.
