That's a really good way of thinking about it, my limited cross guard skills are generally at foot range, whereas K guard I thought was more shin/knee range, but I don't really use either often though....
I've seen both played with the undertook on the leg and on the side hips up, I've seen the cross guard way more inverted but then the k guard I've seen is by big lads who can't invert lol Both seem to have the bottom leg near the leg undertook angled down with the knee sliding between the opponent's legs which is the classic DeathSquad and TriStar entry to the 411 from bottom guard which was why I wondered if they were similar
I'm not familiar with either, so when I looked it up and saw all the cross guard inverting, my back immediately said "no thank you"
Yep it's not so.much the inverting I'm after as entries to leglocks coming off the leg underhook and the inside knee sliding down between the opponent's legs from the k control Never played the cross guard so was seeing if anyone who had had seen the similarities
Look up the Miyao bros ADCC runs and Lachlan Giles last ADCC run. Awesome use of the k-guard but using finger grips instead of a gable grip.
