# Thread: Various problems (with White to play and mate in > 3 moves)

1. ## Various problems (with White to play and mate in > 3 moves)

(EDIT: I've decided to move this from the puzzles by AO thread so that people would not think that these have the same authorship. I don't know who composed this puzzle but like many mate in > 3 puzzles it is deliciously contrived. I've titled the thread "various problems" as I hope to post more puzzles of this type at the rate one per week or so.)

Have we seen this one before?

Why isn't it mate in one?

Not sure what move you think leads to mate in one. But there are only 4 moves which check and none of these are mate.

A) 1. Rxg5+ Bxg5
B) 1. Rg6+ fxg6 (now 2.f6+ is not mate because of 2...Kf7)
C) 1. Rxf7+ Kxf7 (or 1...Bxf7)
D) 1. Bf8+ Kxf6

Perhaps you could qualify your question with a variation.

4. ## Puzzle #1 - Solution

The interesting thing about this puzzle is computers have a hard time finding the solution in normal analysis mode. Solve for mate mode works ok but in normal playing mode it appears as if White's move 3 is just too bizarre to be considered, even though all of Black's moves are forced!

Stay tuned for puzzle #2 in a couple of days.

White to move and mate in 7.

6. ## Puzzle #2 - Solution

The interesting thing about this puzzle is that the white rook can move to just about anywhere along the 6th rank and threaten mate with moving to the fifth rank on the next move. However most files have many ways to prevent the mate and some of those release some of black's pieces and spoil the mate. The one way to prevent this is to play Rg6 which forces Rg4 and then Rf6 can no longer be answered with Bh3 and so Rf4 is force and so on almost until mate.
