A puzzle

“You can never have enough puzzles”, I read in a recent article. It’s hard to argue with that!

In that spirit, and also in an attempt to remain true to the theme of this site, you may like to compare your abilities to those of Irish players and puzzle solvers from 65 years ago. The Evening Herald of November 5, 1952 posed the following question:

Evening Herald puzzle 1952
Irish correspondence championship 1951-52, group F
1… ?

The puzzle was submitted by one of the players, Gerard Mac Gartain, of Drumcondra, Co. Dublin. “It is Black’s move, but the question is: Who wins?”

One of the difficulties of puzzles, problems, and studies is that the solver is usually on notice that there is something of interest present: there is a warning bell that isn’t there during a normal game. So for this puzzle I won’t say whether it is very hard or very easy or something in between.

Answer in a few days.

Irish championship players

John O’Hanlon’s long-standing record of nine Irish championship wins has been equalled by Stephen Brady, but O’Hanlon still holds one record: he competed in 29 championships.

Even here his record is in some danger, with many currently active players nipping at his heels. The next highest numbers are: Eamon Keogh (28), Colm Daly (27), Anthony Fox and Philip Short (25), Gerard O’Connell (24), and Stephen Brady (23).

For these and other facts, see the full list, and the same in alphabetical order.

I haven’t fully checked other records, such as longest span between first and last championships or most consecutive championships played. For the first, I think Eamon Keogh holds the record (54 years: 1962 to 2016), followed by J. A. “Porterfield” Rynd (48 years: 1865 to 1913) and O’Hanlon (43 years: 1913 to 1956). The second is complicated by the fact that in many early years no championship was held; if we limit it to number of consecutive years in which a player competed in an Irish championship, then O’Hanlon has 13 (1928 to 1940), equalled by John B. Reid, Irish champion in 1961 and 1962 (1951 to 1963), both exceeded by Anthony Fox’s 17 (1995 to 2011).

The list is based on the Irish Championships page at David McAlister’s Irish Chess History website, which contains player lists for almost all championships, making it possible to run scripts to extract number of championships played.

Roycroft-Walsh, Tormey Cup 1952

The renowned endgame study composer A. J. Roycroft was born in London in 1929. He’s probably best known for his founding and long-time editing of EG, a long-running journal devoted to endgame studies; he also wrote the book Test tube chess: a comprehensive introduction to the endgame study (1972), among others.

It’s not as widely known as it might be that he has a strong Irish connection. He was an undergraduate at Trinity College, Dublin from 1949 to 1953 (French and German Languages and Literature), and throughout those years he was an active player in the local chess scene. Only one game of his is given in the ICU games archive, though to make up for the sparsity it’s a spectacular win against three-time Irish champion Dónal J. O’Sullivan, from the Armstrong Cup 1952-53.

Roycroft-Walsh, Tormey Cup 1952Here’s one more game, versus J. J. Walsh in the Tormey Cup 1952 (source: J. J. Walsh scorebook). This time it’s a loss: from the diagrammed position play continued 16… Be7, and then Roycroft snatched a pawn with 17. Qb8+ Qd8 18. Qxb7 but quickly ran into trouble.

A. J. (“John”) Roycroft also has one other strong link to Ireland I wasn’t aware of before I read his on-line bio: his father Benjamin Francis Roycroft, was born in Killarney in 1896.

Irish championship 1999

A report for the Irish championship 1999 has been added to the collection here: see the Irish championships and Tournaments pages.

The tournament was held in Drogheda for the first, and so far only, time ever. The turnout was excellent for a non-Dublin venue at 18 players, including 5 former champions, and was hard-fought with the result in doubt until the end. The late Tom Clarke had a clear lead with two rounds to play, but lost the critical round 8 game against Colm Daly, who won again in the last round to record his second consecutive championship, with Clarke in clear second.

There were many interesting games, but one that particularly caught my eye was the penultimate round game between John Nicholson and Peter Cafolla. After some eventful play, the following position was reached, with White to play. How should the game continue with best play?

Nicholson-Cafolla, Irish championship 1999

I confess I did not find this too easy, and I was taken by surprise by engine analysis, which seems to me to be not too obvious. I think it’s a good exercise and readers are encouraged to give it some serious thought.

Armstrong Cup 1948-49: Sackville

Congratulations to Gonzaga, who have clinched the Armstrong Cup for the third time in a row, with a round to spare.

Details of another past season have been added to the Armstrong Cup page. In 1948-49 the event had eight teams: Dublin (holders), Colmcille, Dublin University A & B, Eoghan Ruadh, Sackville, Setanta, and U.C.D.. Matches were over six boards, each team played each other once, and the competition was decided by match points.

(It’s striking how the scale has changed over the years. The Armstrong has essentially doubled in size—12 8-board teams instead of 8 6-board teams—and in 1948-49 there was just one lower division, the Ennis Shield. The season was also compressed, running from mid-November to the beginning of February.)

The event was well covered in the papers, and we have partial scores of all but three matches, though results of adjourned games were not reported and no final table appears to be available. Dublin lost to Sackville and later to Dublin University A. Colmcille were strongly in the running, and were joint leaders with Sackville after three rounds. They drew against Sackville, and either drew or lost against Dublin. In the end Sackville won, for the 15th time, with an undefeated record, though they drew at least one match, possibly two.

The Sackville team was Charles J. Barry (7-time Leinster champion, starting in 1912), D. G. Jackson, Matt Ryan (later Leinster champion (1958)), Paddy Duignan (Irish champion 1947), Tom Tormey, M.[aurice] Sheehan, and Barney O’Sullivan (Irish champion 1939 and 1946). O’Sullivan played two games, and apart from those exceptions Sackville fielded the same team in every match.

Note (July 16, 2017): modified to add Sheehan’s first name.

National Club Championship 2017

Congratulations to Gonzaga, convincing winners of this year’s National Club Championship, retaining the title they won for the first time last year.

The event has greatly improved over the past couple of years; this must be due in significant part to the rule changes brought in that make teams more representative of the clubs throughout the year. This year the event was almost too successful, since with only 4 rounds it was not possible to distinguish well between the teams that finished in 2nd-5th places.

One of the best aspects of the entire event was the live commentary by Alex Lopez and Stephen Jessel. I only caught the last half an hour or so, but is was very well done and entertaining. Here’s hoping we will see more such coverage for future events.

How?

Tournament reports have been added for the Bunratty Masters 1999 and 2006 editions. As always, there was much interesting chess in both.

But there were also some puzzling games. Now it must be emphasized that even when a game is available, it isn’t always the full game, and even when all the moves are present, the reason for the game’s end may be missing. For example, sometimes one player loses on time. Or the game continues but both players are short of time, stop recording moves, and one player blunders. Although it’s possible to record all this information, for various reasons it’s often lost in databases.

Van Voorthuijsen - Kane, Bunratty Masters 2006 In the Bunratty Masters 2006 there was one very striking example. In the first round the English player Robert Kane, as Black against the Dutch FM Peewee Van Voorthuijsen, reached the diagrammed position after 31… Qh3, when the game breaks off. White is utterly lost, e.g. 32. Qb5 Qxh2 33. Qf1 Bg2.

(Put it this way: Komodo 9.3 evaluates it at -28.45 after 31… Qh3.)

But the result was 1-0!

The version in the ICU games collection ends with “…”, indicating that some moves have been omitted. It would be interesting to see how White could have recovered. Does anyone have information on what exactly happened?

Heidenfeld-Reilly, Irish championship 1964

No sooner had the last post been published, with its statement that only one game was available from the 1964 Irish championship, than David McAlister emailed to say that he had a second in his collection, and a significant one too: it’s the crucial Heidenfeld-Reilly clash in round 4 that effectively decided the championship.

We’re still not sure what the original source is, but this game matches the contemporary descriptions given in newspaper reports. One puzzle from the reports was that one claimed that Reilly had the advantage at the adjournment, but that Heidenfeld won a pawn a move after the resumption and the game a few moves later. Even in those days, without the aid of computers, it seemed surprising that a player of Reilly’s strength and experience could go wrong so soon after an adjournment.

The game score makes it clear that Reilly’s advantage at the break was solely in material terms: he was dead lost, and indeed the only slight surprise is that he bothered resuming.

Heidenfeld-Reilly, Irish championship 1964The critical point came a little earlier, in the diagrammed position, with Black to play.

White had been pressing earlier but Black would now hold some advantage after 36… Qd5. Instead Reilly played the tempting but dangerous 36… Rd1+?, and after 37. Rxd1 Rxd1+ 38. Kh2 followed with the decisive error 38… Ra1? (instead of 38… Rd8, say, when it seems White holds a slight advantage in complications). There followed 39. Qd4! Ra4 40. Qd8+ Qc8 41. Qd6+ Ka8 42. Qc7, where the game was adjourned, with the weakness of the back rank spelling doom for Black.

While Black had some chances, all in all the impression given is of a deserved and reasonably convincing win by Heidenfeld, and in turn this means a deserved and reasonably convincing championship

Irish championship 1964

The recent posts on the game Oliff-Keogh prompted me to look up the details of the main event with which it was associated, the 1964 Irish championship.

That year’s event suffered several problems that turned it into one of the least memorable championships. It was planned as a 10-player all-play-all, a format that has been used many times for the event. But in this case one of the drawbacks manifested itself: several late withdrawals threatened the viability of the entire event, and it was only by drafting the London player R. W. O’Brien from the Open that it was possible to hold an 8-player all-play-all. Furthermore there were really only two main competitors, the defending champion Wolfgang Heidenfeld and the even-more-veteran Brian Reilly. In the event Heidenfeld won their individual game and cantered home to his third title. At the time the consensus was that the championship was ‘sub-standard’.

31… ?

Only one game seems to survive from the event (but see next post), the second round encounter between Heidenfeld and O’Brien. The critical point is shown in the diagram. Let’s leave this as an exercise: how would you evaluate this position with best play? Answer in a few days.

A full tournament report has also been uploaded.

Missed opportunity

The very welcome news that the ICU is offering two norm events in Tralee in April brought back memories of other recent norm events and opportunities. One such event was the City of Dublin IM Norm Tournament 2011. No norms were achieved; Stephen Brady finished on 6/9, ½ point short of recording his first IM norm.

Stephen had one missed opportunity, late in the event, that I have never seen pointed out. In his game in the penultimate round, as Black against the Scottish IM Stephen Burns-Mannion, the following position was reached after White’s 81. Bc6-b5.

Burns-Mannion - Brady, City of Dublin IM Norm Tournament 2011
Burns-Mannion – Brady
City of Dublin IM Norm 2011

Stephen now played 81… Kc3?, after which the Lomonosov tablebases show that there is no win; the game dragged on to move 112 before the draw was agreed.

But in the diagrammed position, there was a momentary opportunity for a knockout blow. After 81… Nd5! (and if 82. Ba6 Nc7 etc.), Black wins a second pawn or liquidates into an easily won pawn ending. White’s best appears to be 82. Kf1, but after 82… Ne3+! it’s hopeless, e.g., 83. Ke2 Nxc4 84. Be8 g2! 85. Kf2 Ne3 and White can resign.

[Click to replay the full game.]

[Update, January 27, 2017: It later occurred to me that the ‘etc.’ above was too casual: Black is indeed winning but it’s not a simple matter of being two pawns up, since the g-pawn will soon drop. After 81… Nd5! 82. Ba6 Nc7, if we placed the white king on g1 it would be a draw, whereas on e1 White is lost. The difference? On e1 White will be one tempo short of being able to stop the b-pawn. So: 83. Bc8 Kxc4 84. Kf1 (84. Bd7 Nd5) 84… b5 85. Kg2 b4 86. Kxg3 b3 87. Kf3 Kd3! (the only move to win; 87… b3? 88. Ke2 b2 89. Bf5 Kc3 90. Kd1; 87… Kc3? 88. Ke2 Kc2 89. Bf5+ Kc1 90. Kd3 b2 91. Kc3) 88. Bf5+ Kd2 89. Ke4 Nb5 90. Kd5 Na3 91. Kc5 b2 92. Kb4 Nc2+. In the game, once the white king got to g1 it was never going to be possible to set up the same opportunity.]
