there's basically 2 ways:

1) push hard pre-flop (maybe 6~10 BBs if he's really a maniac) and harder on flop if you hit... maybe give away if you don't hit (you hardly can know where you're at if you get a flop like 59Q)

2) push normally pre-flop (maybe 3~4 BBs) so it's easier to give away if you don't hit (what will happen about 70% of the times)


depending on the flop, a potsize bet may help since, in case he didn't hit anything, he probably won't call (unless, of course, he has Ax, which is a very good hand to call anything)

otherwise I think giving away or calling small bets is ok
what you think?

I don't think a maniac will call 6-10 BB's with garbage cards. And heavily raising with AK out of position is not wise cause you could be betting against other pocket pairs without knowing.
