Reddit reviews Guerrilla Jiu-Jitsu: Revolutionizing Brazilian Jiu-jitsu

I'm also a big fan of ko uchi, and transitioning straight into a knee cut pass before they can establish half guard.

Edit: Also Dave Camarillo's stuff (I think he posts on here occasionally) is well worth a look if you're thinking about this. https://www.amazon.co.uk/d/Books/Guerrilla-Jiu-Jitsu-Revolutionizing-Brazilian/0977731588

There is a book by Dave Camarillo called "Guerilla Jiu Jitsu"

He's a world class judoka that also has a black belt in BJJ. The book is all about the transition from throwing to the ground. Full disclosure: I have never trained Judo, only BJJ, but I lurk on the judo subreddit b/c I think judo is awesome. One day... but first have to stop sucking at BJJ. The book is quite good and has good reviews, but just a warning that he comes off a bit petulant in the book. I think it was written when he was younger and bit angrier at the world. If you watch any of his videos and interviews now, he's super chill.

Here is what I do. I try to focus on the sports/rules specific differences and train in a way that improves my training the most.

In Judo, since the pace is a lot faster, you'll need to apply techniques (guard passing, sweeps, transitions) quickly and avoid positions where you are likely to get stuck in like closed guard, half guard, etc. The open guards like spider and butterfly are good. For passing, I favor toreando style and leg drag passing with a slight modification since you can't do standing passes. When sweeping, emphasize sweeps that get you to mount so you don't have to pass. Also since the Judo rules reward pins, practice your control from dominant positions and work on your pressure.

I try to grapple with strengths of the likely opponent in mind as well. In Judo, opponents have really good back defense (from all the turtling they do) so practice turning over the turtle and master your bow/arrow choke. Also, spend some time your transitions to newaza following a throw. This is one of the best aspects of the Judo game.

Dave Camarillo's Guerilla Jiu Jitsu book goes into length about how to mix bjj and judo.

In the end, you'll end up with good throws and an explosive and dynamic bjj game.
