Call, and push the turn if it is a diamond (since he might not have the flush draw, and if he does, you have a redraw), or a non-diamond other than 6, 9, or Jack.

Actually, a read more about his likelihood to semi-bluff raise would be usesul. I'm assuming a very large range, like this.

Board: 7d 8d Tc
Dead:

equity win tie pots won pots tied
Hand 0: 44.067% 42.11% 01.96% 20010 930.50 { KdKs }
Hand 1: 55.933% 53.98% 01.96% 25649 930.50 { 77+, AdKd, AdQd, AdJd, AdTd, J9s, 97s, 87s, 6d5d }


So, if a 2c shows up, for example, it changes to this.

Board: 7d 8d Tc 2c
Dead:

equity win tie pots won pots tied
Hand 0: 45.881% 44.84% 01.04% 947 22.00 { KdKs }
Hand 1: 54.119% 53.08% 01.04% 1121 22.00 { 77+, AdKd, AdQd, AdJd, AdTd, J9s, 97s, 87s, 6d5d }

And a Qd makes it look like this,

equity win tie pots won pots tied
Hand 0: 42.846% 41.94% 00.90% 812 17.50 { KdKs }
Hand 1: 57.154% 56.25% 00.90% 1089 17.50 { 77+, AdKd, AdQd, AdJd, AdTd, J9s, 97s, 87s, 6d5d }

But a 9, for example, leaves you pretty bad vs his range.

So, without more of a read, I think pushing a good turn is good, and c/f a bad turn is good.

But if you can narrow his range some, you might be able to just fold to the flop raise. Vs many of the guys I play with, I'd fold. But pushing is not very appealing either. And calling still leaves you with a big committment problem OOP. So, I say call and conditionally commit based on the turn card might be OK. And folding is OK, too. I wouldn't just push the flop, however.
