the reason you do this with a big hand, is the reason you don't do this as a bluff.

I guess it depends a lot on your thoughts of the villain, but I was thinking this may even be for value. Against some people this is very good, against some very bad, I don't think anyone here can tell you.

edit: didn't realise flush got there on turn, I like it more, still not a lot though. I think he expects you to bet with your good hands and maybe c/r with nuts. If he is good he probably realises that it's nuts or air and given your flop play it's probably air a lot more often.
