looks to me like hes got top pair, probabley a-10. A call on the flop and a reraise on the turn told him you had sumthing strong. I woulda reraised 2x his raise on the flop, then if it was checked to me on the turn,i woulda put out a 5 dollar bet, if he raises into me agian on the turn eather he wants to see a free card with his top pair to catch two pair, or has a lower set/two pair. In which in this case i would reraise him again enough to keep it to where if he calls hes pot committed.... Minimum raise here without showing weakness would be about 5$,, so i'd reraise about 8$ total and hoped he called. Why i would do this play is for two reasons.. First most ppl who hit top set slowplay.. Second he may think your playing back at him or trying to represent a stronger hand. Just confuse the fuck outta him with the reraise on the flop. and put in a raise on the turn to pot commit him.
.. and the reraise protects agianst any straight draws too on the flop
