I disagree. This is a valid way to counter ikkyo, if the technique is done poorly. Okay, it's not really aikido, but it does effectively point out when nage is doing a technique poorly.
It is not really Aikido, but it is a valid counter for ikkyo?
That sounds a bit like home-brew chickensoup made of oxtails, does it not?
If you are just having fun with this, great. If it helps you improve your ikkyo even better!
But if you are serious about learning Budo you want to know why this is not considered a valid counter to ikkyo.
On the other hand, you may very well be the exception to the rule that gets away with it! And then you are right after all !
