You said this was earlier in the tourney so your raised bet in itself could signal an attempt to steal blinds esp with three left to call and two ultimately doing so. From your post the table has had a chance to play at least 30 or so hands (seeing how you folded the two times you had the button and this was your first hand you actually played we really need you to give us more info because you have it).
Here is what I am looking at right now you raised big, got called hit top pair with a second pair to go with it with decent kicker. Without knowing how this guy has played his previous hands what was shown and what he plays and wins with its very hard to give any kind of read.
One way to look at it could be that when you raised the blinds are acting late in the turn pre-flop. Your raise itself was big but not all that big in comparison to what this guys chip count may have been. (you said T1000 going with he won at least two pots by your post he could have some where in the neighborhood of about 1300 in chips????? he has ten out there with a decent cushion against a drawing hand I wouldn't put it past him to be holding a small pocket pair like 4's or even 8's )
There is so much information we are not getting from you though did he call quickly ??? is that how he calls??? did he have to look at you ????? Has he been caught bluffing yet???? There is alot of info there we are not getting, could you let us know how this turned out.
Without hearing all avaiable information I would guess that you are beat and he is holding a set or something larger.
