You're looking at a coinflip situation at best. The best your equity in this hand could be is probably 60% given the majority of his possible holdings, including a bare flush draw with an overcard or two. There are a couple of hands that have you crippled. Against his range of hands you are probably even money.

If you're looking at a coinflip at best and don't have fold equity you should just call. If your flush draw is higher you can play it a bit more aggressively.

If you're playing laggy, people will often make frustration calls when you hit your hand anyway, so you get paid off when you make your hand and lose less when you don't.
