After last week’s dip into the unorthodox, a relatively
straightfoward one for Easter.
The black rook is tied to the defence of h7, and the white knight and rook must maintain the threat of mate, so the white king must deal with the free e-pawn, and White must also cope with a potential check from the rook which would allow the black king to escape. The key, 1.Rh2, anticipates the position four moves ahead, with the king on e2. 1...e5 2.Kb5 e4 3.Kc4 e3 4.Kd3 e2 5.Kxe2 and now 5...Rg2+ can be met by 6.Rxg2 any 7.Rg8 mate.
