White to move
My bishop is prepared to come to d7 with tempo, then the other rook can join the fray and all of my pieces will be aiming at White's royal family while his pawn storm is less threatening than the skiff of snow that fell on my deck overnight.
20.Nc3??
20.Qa3 seemed necessary.
20...Bd7 21.Qa3 Rfb8
My opponent realized the hopelessness of his position and wished me Happy Holidays!
