First one i've solved.
I saw the comments about Bb5+ and thought of it too, but with Kd1 it doesn't seem to work. Then I saw someone else mention Kd1, making me double check it with Fritz, which says it's a dead draw after 1. Bb5 Kd1.
The puzzle is an interesting one.
Great puzzle. I actually found the solution fairly quickly because I noticed the many possibilities of knights forking the king and queen. I tried to make the fork work and quickly found the given solution.
Eighth page... I solved it pretty easily, once I realized that what I thought was the queen was actually the king.
