2.) I dunno, I just, uh, chamber?
3.) Probably not 1handed. You will be far more often out of reach to chamber than with polearms or twohanders.
4.) (speaking as a twohander): chambering sidewings is hardly worth it. Not only because those are harder to pull off, but also people manage to block those more often for some reason.
5.) Str_KpuBopyk is actually a pretty good call. It's like fighting Urist with the addition of the occasional chamber (his ryhtm goes like: block, block, block, block, block, block, chamber...) but unlike khorin, and occasionally Phyrex, this guy NEVER falls for held swings.
Speaking native wise: M. That guy is chambering thrusts like a bitch all the time
