IMO if you take the lead away from him on the river you 'll get your bet but little more.
If you risk youir bet by checking to him, and he bets, then I always take a lengthy pause ( i'm unsure of myself) and the reraise. This usually pays off handsomely.
I've been trying to "reraise right away" within 2-3 seconds, as I often see big pots created by someone else who does this. Truth is, this seldom works for me. I think my table image is that I too often have a strong hand when I raise, so a quick raise just adds to that image and they fold.
What are your thoughts here.
