Read dependent and image-dependent. You reraise pre, have you done that with lots of hands or can he with some certanity put you on a big pair here? If so, you have told him "I have a big pair". He knows you are pretty keen on calling a raise then, but still raises. Not all-in, which he probably would have done with the flushdraw. I think you have to put him on trips here if you do the puzzle. But again, this is very read and imagedependet I think.
