Another strategy agaisnt a maniac.... just leave. That's the beauty of online poker.

Your only real poor play was calling the massive reraise on the 774 board. I bet you wouldn't have done that if not for the maniac getting you out of your rhythm.
If you are going to be out of rhythm its probably better to just move tables and save that fight for a later day.

I think you played all the hands ok. AKs and TT are fine hands to push against a maniac, you'll win a lot more often than you lose. The A7 hand I probably do the same. Usually they won't make a big raise if they have the boat, just call, the big raise is often an overpair or a 4 with a worse kicker.
