A few things I picked up myself from playing against Hazama 60% of the time I was playing today.
j.D from the other end of the screen is probably as safe as 2D. If you're far enough, I believe you don't have to worry about the snake getting from any direction--as long as Hazama doesn't move closer. If you're far but within range for Hazama's long range snake, you'll have to rely on your reflexes to guard it.
NEVER use 236x unless you're quick enough to react when the snake disappears. If you use 236x too early and the snake is still there, you'll get hit. Otherwise, if you time it right, you can punish and close in as well.
5D is never safe in this matchup. Captain Obvious, over and out.
