Murdoc’s Chess Problem of the Day

Solution to 10/23 Problem: (highlight to reveal)
1. Kc2

The book I’m pulling these from only gives one move for the “mate in two” problems. This one isn’t all that difficult, and it seems that the options are: 1. Kc2 Ka3 2. Qb3++ or 1. Kc2 Ka5 2. Nc6++. Are we buying that?
