The first three moves were easy to find, but I nearly missed the discovered check at the end of this:
1. Qd4 Kg5
Or [1. …Kf3 2.Qe4 Kf2 3.Rd2 with mate on the next move]. Continuing:
2. Rg1 Kh6
3. Qh4 Kg7
And, here, I went round and round with Qh7+, but couldn’t corral the damned king no matter what I tried. Only on backtracking did I even notice the possibility of a discovered check:
4. Be8! Qg3 (only move)
5. Rg3#
1. Qd4+ Kf4
2. Nd2+ Kg3
3. Qg4+ Kf2
4. Ne4+ Ke3
5. Rd3#
OR
1. Qd4+ Kxg5
2. Rg5+ Kh6
3. Qh4+ Kg7
4. Be8+ Qg3
5. Rxg3#
OR
1. Qd4+ Kf3
2. Nd2+ Kg3
3. Qg4+ Kh2
4. Nf3+ Rxf3
5. Rd2+ Kh1
6. Qg2#
1. Qd4+ Kxg5 2. Rg1+ Kh6 3. Qh4+ Kg7 4. Be8+ Qg3 5. Rxg3#
1. Qd4+ Kf3 2. Qe4+ Kf2 3. Rd2+ Kf1 [3. … Kg1 4. Kg2#] 4. Qh1#

1. Qd4+ leaves the least options for black.
2 possible variations…
1)
1. …, Kxg5 leads to a peculiar discovered lather mate
2. Rg1+, Kh6
3. Qh4+, Kg7
4. Be8#
and the other option
2)
1. …, Kf3 which leads to a slightly longer variation
2. Bh5+, Kg2
3. Qg1+ (most forcing, other options were Rd2+ aso)
4. …, Kh3
5. Qg4+, Kxh2
6. Rd2+ leaving only the desperate Rf2 which only delays the mate comming on g2.
1. Qd4+ Kxg5 (1… Kf3 2. Qe4+ Kf2 3. Rd2+ Kf1 4. Qg2+ Ke1 5. Qe2#) 2. Rg1+ Kh6
3. Qh4+ Kg7 4. Be8+ *
this seems to be a nice little king hunt:
1. Qd4+ Kxg5
2. Rg1+ Qg3
3. Rxg3+ Kh6
4. Qh4+ Kg7
5. Qh7#
1. … Kf3
2. Nd2+ Ke2
3. Qe4+ Kf2
4. Rf1#
2. … Kg2
3. Rg1+ Kxh2
4. Qh4#
3. … Kh3
4. Rg3+ Kxh2
5. Qh4#
greets, jan
Looking for enforcing moves I guess it should start with:
1. Rf1+ Kg4 (Ke3 Qd3#)
King can’t take g5 pawn becauce of Bf5 followed by Qg4/Qg6.
Further I guess:
2. Rg1+
Looks like a good place for the rook.
Must be answered with Kf3/Kf4, otherwise Q mate in h file.
Seems that white’s next 3 moves shall be the same in both cases, just in different order:
a)
2. … Kf4
3. Qd4+ Kf3
4. Nd2+ Ke2
5. Bd3#
b)
2. … Kf3
3. Nd2+ Ke2 (Kf4 Qd4#)
4. Bd3+ Kf2
5. Qd4#
or if black plays Kf2 befor Ke2, again another order of the same moves.
Mate in 5 it seems to be 🙂
ward yancey says Qd4
Correction:
I see now that the two lines I gave in my first post, were only side lines. I strangely overlooked
black’s 1. … Ke3.
1. Rf1 Ke3
2. Re1
Looks like the best, but several variations occur:
a)
2. … Kf2
3. Qd4! Kxe1 (variations exist)
4. Qg1+! Ke2 (Rf1 Qe3#)
5. Bd3+ Kf3
6. Nd2+ Kf4
7. Qg3#
b)
2. … Kf4
3. Re4+ Kxg5
4. Bf5+ Kh5
5. Rh4+ Kxh4
6. Qg4#
c)
2. … Kf3
This must be the very main line I think. Several checks for white, and also many escapes for black.
Difficult to get queen into play.
This is a tough one ….
1. Qd4+;Kf3 (KXg5 loses quickly to 2. Rg1; Kh6 3.Qh4+; Kg7 4. Be8#) 2.Rd3+, Ke2 or g2 (both lose)
1. Qd4+
if 1. – Kf3
2. Qe4+ Kf2
3. Rd2+ Kf1
4. Qh1++
1. – Kg5x
2. Rg1+ Kh6
3. Qh4+ Kg7
4. Be8+ Qg3
and
5. Rg3++
For @pht
“1. Rf1+ Kg4 (Ke3 Qd3#)”
Ehm… Qd3#… ?
The Queen can not go in d3.
🙂

1.Qd4+ leads to a mate. Black’s best try is
1. …Kf3 (1. …Kxg5 2.Rg1+ Kh6 3.Qh4+ Kg7 4.Be8#)
2.Bh5+ Kg2
3.Qg1+ Kh3
4.Rd3+ Kh4
5.Qg5#
At move 4, black can delay the mate by sacrificing Queen and/or rook.
Hello,
A tactic refers to a sequence of moves which limits the opponent’s options and may result in tangible gain. These are usually contrasted with strategy, in which advantages take longer to be realized, and the opponent is less constrained in responding. Thanks a lot…
