2 folds, MP1 raises to $0.15, MP2 calls, MP3 folds, Hero calls, 3 folds.

Flop: ($0.52, 3 players)
MP1 bets $0.15, MP2 calls, Hero raises to $1, MP1 calls, MP2 raises all-in $7.59, Hero folds, MP1 folds.
Uncalled bets: $6.59 returned to MP2.

Final pot: $3.52

Just wondering whether I played this right, I have no reads on him whatsoever, he simply smoothcalls, than raises all-in? Doesn't seem to be a flushdraw, I'm pretty sure he would re-raise with two-pair, so by far the most likely hand is K10 correct.?
