[Title "Alexey Grigorievich Kopnin - mate in two - 1948"] [FEN "nR1rB3/2PPPN2/bbk1N3/1p2p3/1p2P1nq/1K1Pp3/7B/8 w - - 0 1"]
In this problem, it’s white to move and mate in two. What is the solution?
In the link (source) there is also a solution but it is in Russian notation and I do not understand it. (Maybe I would not understand it even if it was in English notation) I need to see the exact moves explicitly.
Here is the Russian solution:
1.d4! (угроза 2.d5#) 1…ed 2.Kfd8# 1…K:c7 2.Ked8# 1…C:d4 2.cdK# 1…Kf6 2.edK# 1…Л:b8 2.d8K# (1…Л:e8 2.deФ/C#)
What move is the "1…ed" for example? There are just two columns "ed" but what is the row number and what piece should be moved and where?
