Bonus for restricting opponent's piece moves STC: LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 51883 W: 11297 L: 10915 D: 29671 LTC: LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 15859 W: 2752 L: 2565 D: 10542 Notes: (1) The bonus value has not been carefully tested, so it may be possible to find slightly better values. (2) Plan is to now try adding similar restriction for pawns. I wanted to include that as part of this pull request, but I was advised to do it as two separate pull requests. STC is currently running here, but may not add enough value to pass green. Bench: 3679086
