You should stay out of people's closed guards any way. There's no such thing as a closed guard pass, where you are supposed to start there, in the closed guard. Plus, you never know what's lurking there. We got a guy in our school and his triangles are nasty, you can protect all you want, but once his guard is closed, you're pretty much done. You want to pass the open guard, it's the only way you for sure have a chance.
Will, I'll be honest with you. I don't try to get top position unless it falls in my lap, I take someone down and end up there, or I'm in bottom mount/half guard and I need to move. I play a bottom game. If I get on top, my game is still almost identical to the bottom. I like stuff I can get from everywhere. I'd say I'm decently even with the sweeps and passes. I've learned a lot of passes in the past two months, but I don't use all of them just yet..so it's 50/50 split.
