- Apply LMR at shallow depths
- Implement counter move, follow up move and history move pruning
- Implement probcut

Which version of cutechess? I tried cutechess 1.0.0 (it uses Qt 5.9.1) in Windows and it can properly detect the options. Are you running it in linux? Which distro, and which version of cutechess?
