Yes I played On a Computer and It finds Mate in 4.
mate in 4 moves 21. Be3+ c5 22. Bxc5+ Bxc5 23. Qxc7+ Ka8 24. Qb7#
Looks like there was an error at the Site Because actually it do not
move and there was an Error: "Unable to Response". It was a nice
Sacrifice by Rykba.
It saw 13 Moves Ahead to see Mate in 13. And then Sacrificed its Rook.
Beginner Level was just thinking till 8-10 depth deep So it overlooked
13 depth Mate.
Bye
Sanny
