Forgotten Whyatt problem?


One for our Australian friends. A Bill Whyatt problem which does not feature in Bob Meadley’s collection.

Not vintage Whyatt, but still worth solving.

W.A.Whyatt
362 The South African Chessplayer, May 1961

(= 11+11 )

Mate in 3

In a letter to me dated 22 May 1980, Bob Meadley said "Jim Jones found another Whyatt problem from the South African Chess Player dated May 1961. It's number 362". Bob then quoted the above diagram. Bob then continued "I found this one in the Sunday Telegraph 27 August 1961".

(= 8+5 )

The Sunday Telegraph is a Sydney newspaper.

Thanks for posting that one Geoff. A complete block with three tries failing to pinning defences - it's a little beauty. Definitely published in the wrong place!

The full solution is:
1.Ka4? Bc6! (2.Qc4?)
1.Kb4? Rb8! (2.Qd7?)
1.Kb2? Bxd4! (2.c4?)
1.Ka2!
1... R~ 2.Qd7
1... Rd6 2.c6
1... Bc6 2.Qc4
1...Bb7 2.Qxb7
1...Bf~ 2.Se7
1... Bxd4 2.c4
1... g4 2.Sf4

There are also incidental tries with a changed mate:
1.Qb6? (2.Qe6)
1... Rd6,Re8 2.Qd6
1... Bxd4 2.c4
1... Bc6!
1.Qa6? (2.Qe6)
1... Rd6,Re8 2.Qd6
1... Bc6 2.Qc4
1... Bxd4!

The problem shows 3 self-pinning tries, with 3 self-blocks, a battery mate and superb construction. Note how the black pawn on g5 and black rook on d8 block the bishop.

No doubt the problem was published where it was because of a lack of originality. It is clearly inspired by the following famous problem (composed at the Piran Congress 1958), which shows 4 self-pinning tries in a much heavier setting.

C Mansfield, W Massmann & L Loshinski
3rd Prize, Problem, 1959
(= 12+9 )

1.Kg3,Kh2? Bd6! (2.Qf3?)
1.Kh3? Bxe6! (2.Bf3?)
1.Kf1? Qf7! (2.Qe5?)
1.Kg1? Bxd4! (2.e4?)
1.Kh1!

The theme goes back to at least Niemeijer in 1919, and continued to have a life post-Whyatt. van Dijk even won a 1st Prize in 1966 with a 4-fold example.

This is the best example I have seen of the idea, because of the superb and wholly natural construction which you explain. Overall artistry comes ahead of crude number-counting (4 is better than 3) in my book.

It's strange that he didn't keep a record of the problem. It would have made a grand addition to Bob's book.

The problems of Niemeijer, Mansfield/Massmann/Lohinski and Van Dijk have the additional feature -that Whyatt hasn't- of being a complete block where the white King has 8 squares to choose from, and none of them is defeated by check, something called the Le Lionnais theme (after a French problemist who collected problems with this idea). A problem by M. Duchateau from 1884 is quoted as being the oldest example, but that one has no pins at all. Mansfield et al were after four tries defeated by pins, which explains the somewhat heavy construction.

Actually, problem by Whyatt is a complete block.

As far as I remember (but I allow that I may be wrong) in Le Lionnais theme the white king must be mirrored, which is not so in van Dijk's problem. By the way, it hasn't been quoted yet in this thread...

N. G. G. van Dijk

To complete the set:

Niemeijer's problem with three tries, mentioned before by Michael McDowell:

M.Niemeijer
Tijdschrift, 1919, 2nd prize
(= 6+8 )

#2

1.Ka4!, 1.Ka3(b4)? Bf8!, 1.Kc4(c3,c2)? Rc6!, 1.Ka2(b2,c2) Rh2!

I was able to find earlier problem by A. Mackenzie with two tries. By the way, my copy of "Chess Lyrics" belonged to N. van Dijk!

A.Mackenzie
2nd HM, Seventh Tourney, Otago Witness, 1900
(= 9+8 )

#2

1.Kh1!, 1.Kh3? Bc8!, 1.Kg1? Bd4!

Unlike the other examples the Mackenzie is an incomplete block, as the king must make the key to allow 1...Bf6 2.Qg2.

Still, it's a nice problem!

Another problem which is not in the Whyatt collection:

W.A.Whyatt
The Observer 1959 (version)

(= 9+14 )

Mate in 3

I’ll not add the solution in case anyone would like to solve.

A nice example of Whyatt’s quiet style, though the setting is a little heavy.

What does "version" means ? whose is it ? do you know ?

Sorry Jacques, I don't know exactly what it means.

I found the problem in a collection which John Ling produced a few years ago giving all the originals from the period (1955-67) when he edited the chess column in The Observer. It is marked "version" under the diagram, but the solution doesn't elaborate in any way.

So, following what you say, it seems to be a version made by the author before 1967 !

Like Michael, I found this problem (and then passed it on to Bob Meadley) some years ago within Volume 1 of John Ling's "Observer" collection. As I recall from Ling's text, Whyatt's original setting in the "Observer" was cooked; I'm fairly certain that this is a correction by Ling for his collection - and not one by Whyatt, because Whyatt would have noted it and it would have subsequently appeared in Bob Meadley's book. In any case, it's not vintage Whyatt. @Michael: Didn't I mention this problem to you on the phone before? (Rather remiss of me if I didn't!)

If you did Ian I don't remember. I posted it in case anyone who has Bob's book would like to note it for the sake of completeness.

I agree it's not vintage Whyatt.

In Bob Meadley's book "W.A. Whyatt's Chess Problems", problem no.117 is cooked by 1.Bxf6. However, I've just discovered that the problem can be corrected by adding a wPh7, as below!

W.A. Whyatt, Problem 1964 (v)
(= 10+15 )
#3

1.h4! (2.Rxg5+ Kf4/fxg5 3.g3/Qxf7)
1...d3 2.Kxf7 Re5 3.Rf1
1...Se7 2.Rxe6 Re5 3.Rxf6
1...gxh4 2.Sg6 (3.Sxh4,Rf1)

The try 1.Kxf7? threatens 2.Qxe6#. The refutation 1...Re5! self-blocks e5 and so would seem to allow 2.Rf1#, but it has the compensating effect of opening the Ba6's line to f1. The try 1.Rxe6? threatens 2.Re1,Re2,Re3,Ree4,Re7#. The same refutation 1...Re5! this time would seem to allow 2.Rxf6#, but it has the compensating effect of pinning the Re6. After the key, the defences 1...d3 and 1...Se7 each close a line and so nullify the compensating effect, allowing White to proceed with the original plan. Whyatt, in correspondence with Alexander Goldstein, called this strategem "loss of compensation".

Adding a white pawn on h7 means two captures by this pawn, but black has 15 pieces...

Pb6 is superfluous.

In fact, Pb6 would render this position illegal...

Thanks Joost! If the Pb6 is removed then the position is legal!
