A.D.Petrov's checkers problem. White have only four checkers. White to move and wins.
Sort:
I'm under-zero in checkers, no way I can solve this. Seems impossible.
ChessStakhanov, I think you should specify the variant: English checkers, Russian checkers, Italian, Jamaican ... There's no standard in checkers. Kings can fly or not? Men can capture backward or don't? Are there any priorities concerning captures, or I can chose the capture I like.
Russian Checkers, of course.
I think to agree with Serperior, e3-d4 seems the move, Blue must play c1:g5. Then White d4-c5 and g3-h4 next, so winning a king. Then... Blue wins the game?
Samuele, don't hurry.Try once more and write without mistakes.🎡
Genius!!! This is incredible. How can I get this book?

I'm sending PM to ShakhStakhanov for confirmation.
