Yukari is a primarily xboard-protocol chess program. (UCI support exists, but xboard should be preferred if your GUI isn't from the stone age.) Author: yukarichess v.2025.111: Fifth release. I had hoped to get enough strength to achieve 3600 CCRL blitz elo with this, but strength gain has plateaued and it's the end of the month. Estimated strength: about 3550 CCRL blitz elo.
