 {Prize -stunning play, taking advantage of enemy pieces which are overloaded with too many missions. The study leaves a strong impression, while remaining clear and easy to understand.} 1. d8=Q+ Qe7 $1 {The two thematic white tries now fail due to two different obstacles. 2. Rh5+? fails to 4... Re2! and 2. Re5? fails to 2...Rg4+ followed by 3... Be3+!.} (1... Be7 2. Rh5+ Kg4 3. Qd1+ Kf4 4. Rf5+ Ke3 5. Rf3#) 2. Rb4 $3 {Regardless of how Black takes on b4, he must give up one of the two obstacles. White then chooses his plan accordingly. Note that the correction try 2. Re1? prevents 2...Rg4+, but allows 2...Rxe1 and 4... Qe4+!.} ({logical try} 2. Re5 $2 Rg4+ $1 (2... Rxe5 $2 3. Rb4+ $1 Bxb4 4. Qd4+ Re4 5. Qf2+ Kg4 6. Qg3#) 3. Kxh6 Be3+ $1 4.

 {2nd HM - the end positions are known, but two variations are combined efficiently, when the moves Kf3 and Kh3 are correct in one line and wrong in the other. Nh1 comes into play by underpromotion.} 1. Rc8+ (1. d7+ $2 Kxd7 2. Rd3+ Rd6 $19) 1... Kd7 2. Rc7+ {main A:} Kxd6 ({main B:} 2... Kd8 3. Rc1 (3. Bxh2 $2 Bxd6+ $19) 3... Be1+ $1 (3... h1=Q 4.

 {Sp. HM As the composer notes, Liburkin ((Kg5/Ka5, 1935, unsound) made the original matrix with knight and rook promotions. The present study adds value: the undefended rook moves 2.Re6! and 5.Rc6! are noteworthy and the theme of stalemate black defences is doubled, on different squares.} 1. b3+ (1. Re4 $2 Bc7 $1 (1...
