The spectacular study by the French chess master, composer and journalist, Frederic Lazard, could be called "double-entombing" since both kings get buried during the solution. Created 65 years ago, this work leaves even today's computers wondering what is going on. It is a victory of human spirit. Bravo, Monsieur Lazard!
1.Ne4+! Kh4 [1...dxe4? 2.Be1# ]
2.Ng3!! An incredible sacrifice, threatening 3.Nf5 mate.
2...Qf8 [2...Kxg3 3.Be1# ; 2...fxg3 3.Bb6! leads to the main variation.]
3.Be1! Threatening 4.Nf5 mate again.
3...fxg3 The black king is entombed and can't help the black queen.
4.Bf2!! The sacrifice of the second piece is astonishing and leads to stalemates. At the same time, the bishop on the diagonal g1-a7 stops the black pawns.
4...d4 [4...gxf2 5.g3+! Kxg3 (5...Kh3 stalemate.) ; 4...Qxf2 stalemate.; 4...c5 5.Bxc5 Qxc5 stalemate.]
