Hand from live tournament -how do I get rid of this guy???

[Fletch46]

This hand came up in a tournament last week. I don't have all the details but it has been bugging me so if you can help, please do.
$30 freeze out tournament with 140 players, 1500 in chips to start. I didn't know the other player & had just been moved to his table.
3rd level, blinds 50/100, I was UTG with 2200 and UTG+1 had 2400.
With J's, I raised to $300. UTG+1 called. All folded.
Flop QJ3 with 2 diamonds.
I bet 500. He called.
I don't remember turn card but it was a small non-diamond.
I went all in. He called.
