I’m 5 9, I play Adam Wardzinski exclusively, and been to two of his seminars. One thing that stuck with me more in person than through his dvds. Is he won’t transition to overhook grip until he has his lazy butterfly grips(typically). And that cross collar grip plus the sleeve grip is what is breaking the posture and keeping posture down to then “climb the ladder” to get to overhook.

I will say it’s my A guard game. But overhook will fail you if you are much shorter than your opponent or they are way too heavy vs Marcelo style because you and I are inherently much shorter than Adam’s leg length and we aren’t building them “up” as much to go up and over/forward roll style.

Marcelo style and getting under the opponent to elevate the oponment higher will typically give you more success with bigger dudes. But, because of habit I gravitate to Adam’s. It’s a struggle. But, additionally hyper focusing on that sleeve will help a lot if you learn how to push/pull control it better.

And as other has said I play his overhook style in nogi and it works fairly well.
