10-20 heads up

[worm33]

first hand pokerroom.com. Player sits down at 10-20 heads up table with me for $130. min buy in is $100. Usualy these people last about 3 minutes...sometimes they win the 1st hand and leave....usualy they bust out. Ok I get dealt AhTh on the button. he limps, i raise...pretty standard. Flop is j109 2 diamonds. He bets I raise. he calls. offsuit 7 in the turn. He checks, I bet, planning to fold to a checkraise. He calls again. River is another 7. Board j10977. he checks, i check. My thought process here was I was 95% sure I was going to see a jack or a queen...leaned a little more heavily towrds jack. who plays this differently?
