If I had a little more of a hand, I'd defend my blind right here, because it very well could be a raise he doesn't want called. A more dangerous approach that sometimes would work would be to see the flop then push there since you are first to act.

In this spot though, your stack looks good, and him being weak tight, he probably has some sort of paint in his hand right now. I'd fold and steal on the next hand or 2.
