    Beautiful strategy and motivation for the first two moves. I like it very much

    In the first solution the immediate 1.Rxc4-h1(+bPc7)+? fails for two reasons: (1) Black could play 1…cxb2-b7(+wRa1)!, which doesn’t check the wK because c7 is occupied; (2) Black could play 1…Sxb2-b8(+wRa1)+!, after which 2.dxe4-e2(+bSg8) removes the check to the wK. Therefore play must begin with 1.Be2 (preventing 3.dxe4) and 1…Rb7 (preventing 2…cxb2).

    In the second solution the immediate 1.Rxe4-h1(+bSg8)+? fails for two reasons: (1) Black could play 1…Sxb2-b8(+wRa1)!, which doesn’t check the wK because g8 is occupied; (2) Black could play 1…cxb2-b7(+wRa1)+!, after which 2.dxc4-c2(+bPc7) removes the check to the wK. Therefore play must begin with 1.Bc2 (preventing 3.dxc4) and 1…Rb8 (preventing 2…Sxb2).
