When you is rushing at me and is about to draw your bokken I half step to my right just as you about to draw your bokken from your left hip. Then as you diagonal slash from my right shoulder I hit a backflip. Then as you bring the sword to stab me I duck under your stab.
I hope this is correct
Yes, that works. Each of those gets you by, but only barely - the moves I just made had an emphasis on hitting hard and fast - focusing on both speed and power by keeping a flow in momentum.
The strongest "error" point in your move was the back-flip. Because of the method I attacked and the attacks I chose for this combo, during your back-flip I could have simple struck you with the stab, providing I had enough momentum.
Your very first movement, which put you on the outside of my blade, which means I would have turn into the strike, covering more ground, and thus taking a slightly longer time, is simply what allowed you by.
With the attack I used above, here is the movements that would have been a safer dodge, and set you up for a better chance to counter attack (as ducking underneath a stab is dangerous, as the opponent could simply use two hands [ in this case, I would have pushed down on the pommel with my left hand] to bring it into a downward strike, meaning you would be forced to dodge to either side, and again, they would have a way to strike you, staying on the offensive.
Anyway, the counter I would have done would be like this:
*As you step near me to unleash the draw-slash, I leap backwards, making the blade sail past me. Once you step forward and move in with the diagonal slash, I sidestep to my right, turning my body so that it runs "parallel" to your blade.
As you again turn to go into the stab, I simply sidestep again, allowing the blade to sail past me, through the air, by my side. With this, though, as soon as the tip of the blade is cleared of my body, I turn back, so that the edge of the sword would be right by my side, but I use my left and to grab your right hand, since this is the one holding the sword. I then turn and use a powerful punch into your solar plexus.
Me turning into your blade, grabbing your wrist, and punching you was done all in one swift motion.*
Note that my above movements always made it so that the opponent had to use more of their time to turn and face the right way so that they even had the ability to strike me.
Whether you are unarmed, have not drawn your sword, or have, this would have been a very effective way to dodge.
Are you ready to move on to the next part?
I'm going to be attacking, you, and I want you to guard.
