Sumi Gaeshi with a necklock counter to head-outside single?

So, the IBJJF has banned belt-grip Sumi Gaeshi (Hikkomi Gaeshi, if you're a pedant) because it "endangers the neck" despite it being a very common technique in Judo and neck injuries from it being basically unheard of. Jumping a guillotine and pulling the opponent face first into the mat with it is perfectly safe though and so is completely legal.

I've been thinking and it seems the answer to this is to lock around the head/neck and flip them over with Sumi Gaeshi just like if you had a belt grip. Now this is of course many times more dangerous to the neck than belt-grip Sumi and absolutely WILL smash your opponent's head into the mat, but is still legal under IBJJF rules (would get you an instant DQ in Judo, funnily enough).

 

is sumi gaeshi still legal if you grab the gi instead?

also funny because i consider sumi gaeshi of of the easiest/more gentle fall to take for uke.

 

I didn't think of that scenario, now that rule seems extra ridiculous (even more so than before)

 

It's a really stupid rule. It comes up so rarely that if damage was going to be done, it would happen well before the ref could issue a warning.

 

the rule is against grabbing the belt and driving them down on their head

 

This. You can still do sumi/hikkikomi gaeshi or a switch, you just can't spike the guy.

 

Why not a general head-spiking rule then, rather than this weirdly specific one?

 

IBJJF, keeping it real one guard jump at a time.
