I have seen numerous tapes on the vale tudo guard, and I did not expect this tape to be up to par, mainly because it is from WGF. Some of the material from WGF, such as Gokor's and Oleg's work, has been less than excellent. Having said that, this is a solid vale Tudo Guard tape, though not for beginners.
Goes begins by teaching the "Sperry" method of opening the guard. From here, he shows 2 different ways to pass the guard. One was on De La Riva; neither were on Sperry. He shows how to alternate these 2 passes as well as addresses what to do if your opponent grabs your ankles and tries to sweep you. His movement ends in a mount. Now, there is nothing wrong w/ this, but the hands on ankles sweep happens so fast, most of the time you would already be swept before you can begin his counter. On a positive note, Goes goes (whoa that's wierd) into many finer details that make these moves work.
Goes then moves on to guard sweeps and covers the scissor sweep, a knee on bicep sweep, and the elevator. One thing I really liked is that Goes shows several drills to help w/ the moves shown on the tape. These drill will certainly aide in becoming proficient at these moves.
Allan then moves on to submissions and covers the juji gatame, Kimura, and triangle. His setup for the triangle was good, and I have never seen it on a vale tudo tape. He also addresses what to do if your opponent stands while applying the triangle.
My one grip w/ this tape is that the moves are shown pretty much in isolation( i.e. here is a kimura, here is an armbar, etc.). Also, this tape does not discuss strategy, how to hold down your opponent, flows, etc. For this reason, I say the tape is not for beginners; however, it is a good complement to say Sperry or De La Riva's guard tapes.
