1/2 NL 6 max.

Opponent in this hand is not very good. Some hands ago he min raised w QJdd, led a 972 board (1 diamond), called a 1/2 pot raise, then moved in when a Q hit (vs 97). A few hands later he min raised pre-flop with A8, led a 976 board, check-called the blank turn, moved in on the blank river, and showed. A previous note about him says "stubborn. Bets to weakness". He's on $254.

My table image is pretty bad, as I have been raising pre-flop loads. I flopped some big hands early on to get to $500, but the respect from that has now worn off.

Thoughts on my line?
