Thank you Yancey for your Cristmas puzzle. I have just seen it but I have no time to solve it now. It's time to go to bed for me. I wll solve it tomorrow.
V-11.c8=R c22.Rh1+ Kd23.Rd8#
V-21.c8=R Kb12.Rxc3 Ka13.Rc1#
V-31.c8=R Kd12.Rxc3 Ke13.Rc1#It took 8 minutes to solve this puzzle.
The key lines are v2 and v3, of course because of the stalemate that arises after 2.Qxc3.
