good 1h's easily dodge them San usually does.
From what I can tell, the arc of kicks is roughly 120 degrees, and the reach is something like 80cm. So he would have to maintain a distance of no less than 80cm and no more than 88cm (otherwise he would telegraph that he is about to execute a right swing) for the duration of the fight, assuming he was using his Liuyedao. His athletics advantage would make this possible, but there would be virtually no margin for error.
The best tool available to a 1h duelist is the attack nudge, but its reach is much less than kick reach, so it's suicide to attempt one against anyone that uses kick effectively.
A short 3D 1h user fighting a Longsword user that executes kicks whenever the opportunity is available is a tough proposition for anyone. If San could effectively stay in this 8cm annulus, I'd give him a fighting chance, owing to his absolutely absurd swing speed. But maintaining such a tight tolerance on spacing is nearly impossible with the realities of ping, server hiccups, etc.
