Daily Chess Puzzle
Today’s problem is from the 1972 book “Chess Combination as a Fine Art”, a book based on articles published in the 1950s-1960s by Kurt Richter.
Since the start of 2018, I have decided to adopt the style of only saying which side is to play: and not giving an idea if the move wins or otherwise, unless on occasion I think signposting would be helpful. Instead, the problems are posed with the instruction to decide what you would play, as in a game.
White to play: examine 1 Rd5, as played in the game.

Parr v Roos, date and place unknown.
Solution
1 Rd5 loses to 1… Rde8! and the back rank mate threat decides. 2 Re8 Qe8 and it is all over.

White to play: examine 1 Rf7, as played in the game.

Schroeder v Golz, Aschersleben, 1963
Solution
1 Rf7 surprisingly loses to 1…Ra7, and White’s checks are fruitless.

The Black king moves to e8 where it is quite safe, even after the Ra1 enters the game by Re1+. Black’s N and B provide just enough cover, after which Black wins.

White to play

Cording v Cassens, Emden 1975
Solution
1 Re7+! opens up the way after 1….Be7 for 2 Bd5+. Then if 2…Kf8 White mates by 3 Bh6+ Rh6[] 4 Qh6, so Black’s best is 2…Kg7.

Then 3 Bh6+!! all the same, since Black’s rook is tied to the eighth rank: 3…Rh6 loses to 4 Ne8+ forking Black’s king and queen.

Black to play

Wheeler v Hall, England 1964
Solution
A classic; which I have seen before, but for some reason isn’t in Megabase or Chessgames.com.
1..Rc1+!! ( or 1…Ra3+!) 2 Qc1 Ra3+!

3 Kb1 Ra1+! 4 Ka1[] Qa8+

5 Kb1 Qa2 mate.
I am sure Mr Hall went home smiling that evening; and Mr Wheeler, too, probably.

White to play: after Black plays here 1…b5

Norman Littlewood v Rolf Roth, Havana Olympiad 1966
Solution
As Purdy tells us to, ignore threats: after 1…b5, 2 Re8!! wins. Black resigned.

Daroczy v Dozsa, Debrecen 1956

Today’s puzzle is from the current Sinquefield Cup in St Louis. I watched the latter half of this game live, from our holiday villa, unable to sleep. Watching without an engine on, I felt the R+P ending was probably winning for Mamedyarov, but wasn’t sure [one analysis I have subsequently seen suggests So might at one stage have been able to hold].
Near the end, I felt it was going to be a win, but still wasn’t sure.
White to play

Mamedyarov v So, Sinquefield Cup, August 2018
Solution
1 Kg3 (or 1Kf3 or 1 Kh3) wins, as one might expect. But how?
1…b4 2 Kg4 b3 3 h7+! (the key move) Kh8[] 4 Kg5 Rb5+ 5 Kh6 (the point) and White mates.

Early hours of the morning, when So resigned after 1 Kg3, the resignation at first felt premature. I initially tried to stop the b pawn with the Rook, until I saw 3 h7+! which enables the King to ‘hide’ on h6.

Black to play: examine 1 …Qb3, as played in the game.

Damjanovic v Lehmann, Beverwijk 1966
Solution
1…Qb3 loses:

Black’s weakness is clearly the risk of bank rank mate (in CJS Purdy terms, his king is in a net). So 2 Bg5!

If 2…Bg5, 3 Nb3 since the N is no longer pinned by the bishop on e7.
Or if 2…Qa3, 3 Be7 wins a piece. Black must make luft for his king, after which 4ba

White to play: examine 1 Ng5+ Kf6, as played in the game.

Smyslov v Benko, Monaco 1969
Solution
After 1 Ng5+ Kf6, Smyslov played 2 Kf1! after which Benko gave up the rook by 2…Rf2+.

Instead, 2… Rb2 (say) is met by 3 f4, and Black’s king is caught in a net.
He can’t escape: 3…Kf5 4h3 and mate follows.

Horne v Mardle, Hastings, 1953
Solution
1 Nc4! and after 1…Rd3, 2 Rd3! and White ends up the exchange up, with a winning position.
