Me and the duck losing at chess (it was The Duck’s Fault!)
Last week we set the task place 18 Queens (nine of each colour)
on a chessboard without any of the Queens attacking each other.
That is the solution but some lad over at chessgames.com let’s call him ‘Smart Alec.’
has found a way to place10 White Queen and 9 Black Queens on the chessboard.
So my 18 Queens problem is cooked. It is now a 19 Queens problem.
I was looking for something else and I encountered a few ‘Everlasting Pins’ that had
been misplayed because the player did not seem to realise just how good the pin was.
nonkel - bohemia51 RHP 2017 (White to play)
White played 57.Qf3 and won 20 odd moves later. 57.Kg3 Kg8 is Black’s only move then Qxg6.
Robert Matheson - ZorroTheFox RHP 2008 (White to play)
White played 41.Rxg6 but look at the position. 41.f3 when Black runs out
of pawn moves then they have to move the King leaving the Rook to it’s fate.

Also a few days ago I was watching Anand v Aronian draw live game, it went
to a Double Rook Ending. ‘These are always drawn’ came an online comment.
I made a mental note to check the Red Hot Pawn DataBase. It did not disappoint.

That is what I am here for...to educate and pre-warn my readers.
I mentioned Greco when I did my History of Chess and recently I flicked
through Greco’s games and came across a five move game winning a piece.
1. e4 e5 2. Nf3 d6 3. h3 {This is a waster to lose a move.} 3... Nf6 4. c3 {A trap that has been set on Red Hot Pawn 256 times.} 4... Nxe4 {And this pawn has been taken 117 times.} 5. Qa4+ {Picking up the piece on e4. All this was known and shown in 1621.}
Between 2006 and 2019 user Atomick has set this trap 59 times.
So far 25 victims have taken the e4 pawn and lost their Knight to 5.Qa4+
The Babson task was a chess problem task set with the following conditions.
White makes a move that forces checkmate in the stipulated number of moves.
Black's defences must include the promotion of a pawn, to a Knight, a Bishop,
a Rook, or a Queen. White then must promote a pawn to the same piece that Black
has just promoted too and must force checkmate in the stipulated number of moves.
It looks as if Joseph Babson ( 1852-1929) had set an impossible task but
in 1982 one Leonid Yarosh (1957-) published in Shakhmaty v SSSR this.
It is mate in 4. the first move is 1.a7. We will go through all four promotions.
First the Queen Promotions.

Find games from 2019 where a Queen takes a Queen and a Queen mates next move.
Then a Rook takes a Rook and a Rook mates next move then a Bishop, then a Knight
and finally a game where a pawn takes a pawn and pawn gives mate on the next move.
