Let him take the small pots, when he raises, only call with good (or tricky [Low suited connectors, pp's]) hands. When he comes out firing, if you hit something tricky, let him stay the aggressor until you find the right time to open up and reveal your strength. You're there to take his stack, not 1/25th of it. And when you have a relatively good hand, stay strong. Hit him with a few re-raises (if logical to do so...) to keep him in line. If he fires back, you'll have a better idea of where you stand.
