How to Do the Log Splitter Pass in BJJ
The log splitter pass uses a knee in the middle of the opponent's guard to wedge it open like splitting a log. By driving your knee into their tailbone area and posting on the mat, you force the guard open and create a passing opportunity. It is a fundamental closed guard opening technique that leads to various passes.
✓ Key Details to Master
- 1 From inside closed guard, place one knee in the center of their guard
- 2 Post both hands on their hips or the mat for base
- 3 Drive the knee forward into their tailbone area
- 4 The wedging pressure forces their ankles to uncross
- 5 Once guard opens, immediately pass with torreando, knee cut, or stack
✗ Common Mistakes to Avoid
- ⚠️ Knee placed too high or too low
- ⚠️ Not posting hands for adequate base
- ⚠️ Not driving enough forward pressure with the knee
- ⚠️ Pausing after the guard opens instead of passing immediately
- ⚠️ Getting swept while attempting to split the guard
