Glorney Cup 2016

The Glorney Cup 2016 has concluded with a victory for the Irish team (Tom O’Gorman, Henry Li, Luke Scott, Ross Beatty, Scott Mulligan), retaining the trophy from last year, and finishing clear first for the first time since Cardiff 1958 (when England did not send a team). Congratulations on an historic achievement!

All Irish games have been added to the games archive here. As the tournament was held in Daventry, England, the other games are not included in the archive, but here is the full pgn file for the event.

Update, July 24, 2016: the Irish games from the Gilbert Cup have also been uploaded. Once again, this only includes games involving Irish players, but here is the full pgn file for the event.

Joe Ryan achieves final IM norm

Congratulations to Joe Ryan who has achieved his third and final IM norm at the 4th Montcada IM Tournament near Barcelona, June 25 to July 3.

Many thanks to Daire McMahon and Martin Crichton for supplying the news; so far there’s nothing on the ICU website.

As a non-Spanish FM living in Barcelona he naturally has had many opportunities to participate in IM norm events there. He has gone close to a norm before. But more recently he seems to have hit a run of bad form and discouraging results, with corresponding fall in rating. At 2149, he was the lowest-rated player in the event.

As far as I know, he has never reached 2400 on any list, so that is the last remaining obstacle to the IM title. According to the link above, he gains 79 from this event alone.

Irish championship 2016

The Irish championship runs from July 2 to July 10 at U.C.D. (Student Union building in Belfield).

Already the tournament is causing a great deal of discussion, though unfortunately for all the wrong reasons: this year almost all players who would normally be considered contenders have chosen to sit out, with the result that there are only two players rated over 2300 in the event, and none between 2200 and 2300. And even apart from this the field is quite small for a tournament in Dublin at 16: just two years ago there were 30 at Trinity for the 2014 championship.

A preliminary tournament report has been posted here and will be updated round by round. After the third round Stephen Jessel leads on 3/3, a full point ahead of a group of 7 players on 2/3, including Colm Daly.

Update, July 6, 2016: Round 4 results and games have been added. Stephen Jessel was held to a draw by Gerard O’Connell in the last game to finish. (So Paddy Kennedy’s record of the only 100% performance in an Irish championship will stand for yet another year.) In the second-last game to finish Colm Daly beat Gerry MacElligott; a missed opportunity for Gerry as he was fine even half a dozen moves from the end. Next round: Daly-Jessel, which could decide the entire championship.

Update, July 7, 2016: Rounds 5 and 6 have been added. In round 5 Colm Daly had White against Stephen Jessel on the top board, in the most crucial game of the event. Daly was pressing for a long while in a blocked position, well past the first time control, but eventually slipped near move 60. Both players were down to their last minute and living on the 30-second increment but Jessel duly converted. It’s still not over as Jessel has a lead of only ½ over Killian Delaney, and they have already played each other.

Update, July 8, 2016: Stephen Jessel did not have it all his own way against Anthony Fox, who was doing fine until he allowed his bishop to be trapped, but it ended as yet another win for the tournament leader. On board 2, Killian Delaney had Black against Colm Daly and seemed to have had marginally the better of it for a long time; but late on in a drawn ending he blundered and lost. So Jessel is 1&frac; points clear of the field and has played all his rivals. With White tomorrow against Paul O’Neill, a win will clinch the title.

Update, July 10, 2016: Ça y est … Stephen Jessel recorded a convincing victory with 8½/9, equalling the Irish championship 9-round record, and more importantly becoming Irish champion for the first time. Congratulations on a well-deserved victory!

Brian Tomson, series helpmate in 26

We’ve written previously here about the Irish player and problemist Brian Tomson. He played in the Glorney Cup, Armstrong Cup (for T.C.D.), finished equal 4th in the Irish championship in 1965, and represented Ireland in the Student Olympiad in 1967, before emigrating to Australia in 1968. He died in Newcastle, Australia in July 20, 1986, thirty years ago today.

Here is another of his problems:

Tomson, Series helpmate in 26

Series helpmate in 26 (Tomson, 1981)

For those unfamiliar with this problem type, it’s a helpmate, so White and Black are working together to help White mate Black. It’s also a “series” problem: Black will play 26 consecutive moves, with White’s pieces remaining static. All Black moves must be legal, and all but the last must leave a position where Black could legally move next, i.e., there can be no checks in Black’s first 25 moves. Then White plays one move to checkmate Black.

The length of the solution may make the problem seem daunting, but in fact Black has so few choices that it’s quite accessible. Answer in a few days.

[Update, June 25, 2016: see comment for solution.]

5 years of IRLchess

Today marks the fifth anniversary of IRLchess. The very first post was a short one, to whet the appetite, before moving to more substantial topics. Many thanks in all this to my co-author David McAlister, who has contributed many articles over these years.

Many thanks also to all readers—I hope you’ve enjoyed what you’ve read—and to all those who have contributed comments, information, photographs and games.

A famous ending—epilogue

I had never seen the original article in “the Irish chess magazine” that Golz and Keres quoted, but now it has been supplied by David McAlister, for which many thanks. The article appeared in Chess in Ireland, September 1959, p. 7. The author isn’t listed, but J. J. is listed as the general editor of the magazine, so it’s reasonable to assume he wrote this article.

Respect the endgame (B. O'Sullivan-Walsh, Leinster Championship 1952)

From Chess in Ireland, September 1959, p. 7

The content of the article came as a surprise to me. I had always assumed from the description in Chess Combination as a Fine Art that the analysis in the original source was faulty, and that the solution given by Golz and Keres corrected the errors. That’s not stated explicitly, perhaps, but I had always read it as implied.

But as we see from the full text above, the analysis given by Golz and Keres was in fact taken entirely from the original article by J. J. Walsh. Their only further reference to the original comes at the end of their solution (pp. 236-7):

“This instructive endgame shows the uselessness of the knight in a defensive role!,” comments Chess in Ireland. Yes, but at the same time its skilful application in attack!

It’s not explicitly claimed that the original missed both stalemate and improvement, but that would be consistent with what is quoted.

There is one other point that struck me as unusual. The question as posed by Golz and Keres (see clipping two posts back) comments that the endgame “is particularly interesting because of the number of mistakes it contains”. But according to their own solution, there were two errors (1. … Ne4+? and White’s resignation). Tablebases have shown the modern reader that multiple errors are commonplace even at the very highest levels, but even without this information, would a pair of errors really seem so unusual? It seems a rather sour comment to make.

A famous ending—III

J. J. Walsh has scorebooks covering all of his games, going back to the late 1940’s, and in the collection is included the full score of the game from the last two posts. White was Barney O’Sullivan, and the event was the Leinster Championship.

Most of the game was unremarkable: O’Sullivan tamely lost a pawn in the opening, and everything simplified quickly to a knight ending. It could have been a routine win, but instead turned into something much more interesting right at the end. Winding back a few moves from the widely publicised ending, the position below was reached after White’s 60th move.

B. O'Sullivan-Walsh, leinster Championship 1952, after 60w

B. O’Sullivan-Walsh, Leinster Championship 1952
1. … ?

This ending is within range of the 7-man Lomonosov tablebases (subscription required), which show that Black has the unique winning move 1. … Nb4!!.

With the various solutions to the puzzle given in the earlier posts to hand, the reason is clear enough: from either b4 or c5 the knight is poised to come to d3, but from b4 the knight additionally covers d5, cutting out the drawing line given by van Perlo: after 2. Nf5+ Kxh3 3. Kf2 Kg4 4. Ne3+ Kf4 White has no useful checks.

One exclamation mark or two? Without the benefit of the solution to the later puzzle, it seems an exceptionally difficult puzzle, so the double exclamation seems justified.

A famous ending—II

The ending in the last post was given in the excellent book Chess Combination as a Fine Art by Werner Golz and Paul Keres (Pitman 1976), a compilation of puzzles originally published by Kurt Richter in Schach. On p. 149 we have:

O'Sullivan-Walsh, Leinster 1952

Answering the second question first, no, resignation was not justified, because after 4. Ke2 Nc3+ 5. Kf1 Kxf3 White is stalemated, and Black has nothing better.

For the first part of the exercise, after 1. Nxh4, Black had indeed something better. On 1. … Nd3+! 2. Ke3 f2 3. Nf3 Kg3 4. Ke2 Nc1+! 5. Kf1 Nb3 6. Ke2 Nd4+! 7. Nxd4 Kg2 Black promotes the pawn.

The position also featured in Endgame Tactics by the correspondence chess GM G. C. van Perlo (New in Chess 2006), an acclaimed book that won both English Chess Federation and ChessCafe Book of the Year awards. On pages 390-91 we have the same ending, now given as O’Sullivan-Walsh, Leicester 1952, with the variations above. Van Perlo also points out that from the original position White can draw via 1. Ne3+!, e.g. 1. … Kf4 2. Nd5+ Ke4 3. Nc3+ (which went unremarked by Golz and Keres).

And finally the recent and similarly acclaimed Pump Up Your Rating by Axel Smith (Quality Chess 2013) (ChessCafe Book of The Year) gives the game as O’Sullivan-Walsh, Leinster 1952 and takes it up after 1. Nxh4: Black to move and win (pages 260, 264-65). “There are only five pieces in the starting position, but it’s nevertheless very difficult. The exercise comes from one of the books Tikkanen used, and I solved it every second month. I still had problems the fifth time!”

There are two remaining puzzles, related to the game itself. What was the event, since “Leinster” is unspecific? And was White Barney O’Sullivan (Irish champion 1939 and 1946) or Dónal J. O’Sullivan (Irish champion 1948, 1956, and 1957)? Answers in part III.

A famous ending—I

White to play; how should he continue? In particular, if 1. Nxh4, what then?

A Famous Ending, part I

This position, from an Irish game, has featured in several books, including some highly acclaimed recent ones—which stress the importance of trying to work out a solution yourself rather than resorting to looking up the solution in a tablebase: good advice!

Solution and sources tomorrow.

Irish championship 2003

A new report for the Irish championship 2003 has been added to the tournaments pages here. Stephen Brady won for the fourth time, finishing 1½ points clear of the field.

Until this addition, this championship was the most recent for which this site had no report. The problem was that there did not seem quite enough information to compile a full report: the tournament page on the ICU web site gave only final scores, and the ICU games archive gave only 35 games, instead of the roughly 81 that would be expected from those final scores.

The report in The Week In Chess had similar information but also a link to fuller coverage at Dublinchess.com. That link had long since gone stale, but happily the Wayback Machine came to the rescue, and enabled an almost complete reconstruction of the event.

Daly-Short, irish championship 2003The most interesting game of those available is the wild struggle between Colm Daly and Philip Short from round 3.

From the diagrammed position the game continued 47. Rc8+ Kg7 48. Qxe2 Rxe2 49. Rxa8 Qe4?? (49. … Re1! wins) 50. Rg8+ Kh6 51. a8=Q Re1 52. Qf8+ 1-0.
