White to move. What is the best continuation?
Susan,
Can these problems get any easier?
Variation 1 Variation 2
___________ ___________
1.Re8+ Rxe8 1. Re8+ Rf8
2.Rxe8 Rf8 2. R1e7 1-0
3.Rxf8 Qxf8
4.Qxf8
1.Re8+, Rf8
2.R1e7
Mating Attack:
1. Re8+ Rxe8 forced because this is the only piece that can prevent checkmate, the interpositions are less effective.
2. Rxe8+ Rf8 the only choice
3. Rxf8+ Qxf8 the last of the defenders
4. Qxf8#
OOPS! The only way to save the game is with an interposition! At least for a couple of moves.
1. Re8+ Rf8
2. R1e7 threating mate on h7
2. … Qxe7 the only defense
3. Rxe7 renewing the mating threat
3. … Rf7 interposing to buy 1 move
4. Rxf7 and now thier is no defense
5. Qxh7#
A mate in 5 problem is hardly easy. Although most of the moves are forced, the interposition by Black can be overlooked as the best defense. I did the first time through.
1. R:e8+, R:e8
2. R:e8+, R:f8
3. R:f8+, Q:f8
4: Q:f8#
