Increase full depth search reduction when cutNode In addition to the core patch, improve the use of `isTTMove`: - this name was used to mean both `bestMove == ttData.move` and `move == ttData.move`, so i replaced the argument `isTTMove` of `update_all_stats` with `TTMove` directly. - `ttData.move == move` was still used in some places instead of `ss->isTTMove`. I replaced these to be more consistent.
