I have been playing DLR a lot recently. The route to the back is my go-to move, because you can often force it even if someone sees it coming. The DLR also transitions into some really nice sitting guard sweeps. Basically, keep the foot that is not a DLR hook on the other knee, and always push it away. Either it will open up a variety of DLR sweeps and back takes, or allow you to sit up to a sitting guard. From there, you can either use one of Zog's leglocks, or hit one of about 100 sitting guard sweeps
