This is a scary board to be bet at, even if you hit one of your overs it may not be good. It especially sucks if he has KQ or 10-10 (or QJ if he sucks), which I think are a big part of his range. Even if he's betting a flush draw it's tough to call him down. You're only clean outs are non-diamond jacks, so I just dump this, but I'm nitty with AK on these boards. If the flop came with two clubs, it'd be a different story.
