1. Wrong….your theory W: Nd5 B: Rf3+ Your solution falls apart. W must waste a move to capture. 2. Wrong…your theory W: Re8 B: Rb6 your solution falls apart. It guards b7 square at same time threatens check next move. 3. Wrong…your theory W; Rhf6 B: why h6 ? h1Q and your solution falls apart.
Your solution to 2 and 3 are wrong. Care to elaborate how you came up with them ?
Your resolution to 3 is also wrong. W: Rxh2 B: Kg6 W: Rh2g2+ B: Kh5 W: Nf6+ B: Kh6 no mate.
I couldn't find a solution for puzzle number 3. The best I have tried is 1.Rf3 if 1...a1=q 2.Rg3# If 1...Kg4 2.Rhh3 a1=q 3.Rfg3# but in any case if the black promotes to knight then it cant be solved
