1. Kf4 $1 {This is a very clever way to avoid the 7th rank opposition.} ({
The most straightforward way of playing does not work here because the black
is able to obtain the opposition on the 7th rank, which leads to a draw.
Remember that rule, it is very important.} 1. d4 Kb3 2. Kf4 Kb4 3. Kf5 Kb5 4.
Ke6 Kc6 5. Ke5 Kc7 6. Kxd5 Kd7 {At this point it is a draw due to the
