HOCCC: 1904 correspondence match part 2

In the 1903-04 season two correspondence games were played between the chess clubs of Colchester and Tunbridge Wells. The first match can be found here. According to a newspaper article about the match "In game two White (Colchester) lost a pawn in the opening, but by using the knights to best advantage regained the pawn on move 20, and capturing two pawns shortly afterwards secured a winning advantage, black resigning on the 35th move. The Tunbridge Wells Chess Club is a strong one, having won the county trophy in Kent two years in succession. They also drew against Hastings, a notably strong club."

HOCCC: 1904 correspondence match

In the 1903-04 season two correspondence games were played between the chess clubs of Colchester and Tunbridge Wells.

Division 1 round-up

Both Colchester teams in Division 1 finished in the top half of the table. Colchester A finished 4th (6 wins, 1 draw, 3 defeats) with their best results being 4-0 wins against Braintree and Billericay.

Colchester B finished in 6th place (with 5 wins, 1 draw and 4 losses). Their best results were a surprise 3-1 win against Writtle A and a 4-0 win against Billericay. Again there were lot of strong individual results; the B team scored more than 50% on boards 2 and 3.

NECL update

There have been a number of excellent results for the club in recent matches. The C team drew 2-2 with Clacton A, despite being out-graded on every board. Felix Schnell won on board 1 with Clive Bellinger and Phil Daley drawing on boards 2 and 4.

The D team went one better with a 2.5-1.5 win against Braintree C even though they were out-graded by more than 30 points on every board. Adrian Catrinar won his first graded game, Brian Remmer won on board 1 and John Duff-Cole sealed the team win with a draw on board 2.

The A team have reached the final of the knockout with a comprehensive 3.5-0.5 win in the quarter-final against Witham A and then drawing 2-2 with Brentwood A in the semi-final but progressing due to wins on boards 2 and 3 from Norbert Voelker and Nathan Barnes. Brentwood A fielded the league's only International Master (Richard Pert) on board 1. The final will be against Writtle A whose semi-final opponents (Braintree B) defaulted 4-0.

Perhaps most surprisingly, the B team beat regular Division 1 winners Writtle A 3-1 with wins for Nathan, Svein Kjenner and Felix on the top three boards. The key parts of Felix's and Nathan's wins from this match are shown below.

A game from the past 3

The Essex & Suffolk Border League was formed in 1950 and ran for twelve seasons. When it finished there were just five member clubs: Colchester, Chelmsford, Clacton, Ipswich and Bury St Edmunds. The North Essex Chess League was formed a couple of years after the Border League stopped and covered a smaller geographical area.

D Brown, with the Black pieces, is the Colchester player in the game below.

Premature resignation

After a poor result in their first game, Colchester A have won four matches in a row. The most recent match was a 3-1 away win against Witham A to move them up to 2nd place in Division 1. Svein was first to finish, while he was definitely winning was his opponent's resignation premature?

Colchester B

Colchester B have had a good start to the season in Division 2 of the NECL. They finished in 2nd place last season (behind Colchester A) and are currently top after a 3-1 away win against Braintree B and a 4-0 win over Dunmow.

Last minute reserve Martin Harris had a quick win in the match against Dunmow, annotated in the viewer below.

Knockout first round

The first round of the NECL knockout saw the three Colchester teams all playing on the same night. Both the A and B teams had unlucky draws having to play Division 1 teams. The A team were drawn against Writtle A, one of the favourites to win the cup and the B team were drawn against Witham A. The C team had a home match against Witham B. A number of players were not available resulting in the A and B teams having to poach players from the C team.

Colchester C were out-graded on three boards and lost a close match 1.5-2.5, they will now be in the plate competition. The A and B teams were out-graded on every board. Alex was on board 1 for the A team and was unable to hold a difficult position resigning when losing a piece was inevitable. John Duff-Cole played well against a much higher-graded opponent but lost a couple of pawns in the late middle-game. Felix pulled a point back with a good demonstration of the advantage of two minor pieces over a rook and pawn. Nathan then levelled the match after some unsound but dangerous tactics which gave his opponent the chance to go wrong. The final score was 2-2 with the A team winning after bottom-board elimination. For the B team Clive and Martin had solid draws, Norbert maintained his winning start as a Colchester player but result of the night was Svein's well-controlled win against an opponent graded 180 (33 points higher than his own grade) following an early piece sacrifice.

Two games are shown in the viewer below - the wins from Felix (annotated by Nathan) and Svein (annotated by Svein).

Nadia is British Girls U11 Champion

Nadia Jaufarally, playing in the British Championships in Warwick, has just become British U11 Girls Champion. Her score of 5/7 came from 4 wins, 2 draws and a defeat in the last round - with six of her games being against higher-graded opponents. The game below, from round 6, is a good example of how to play for a win in a very even position and shows strong endgame technique, her opponent is graded 155 - 57 higher than her own grade.

HOCCC: Capablanca visits Ipswich

The text and game below are taken from the 28th October 1919 edition of the East Anglian Daily Times. The only alterations made are those necessary to "translate" from descriptive to algebraic notation. There are errors in the comments in the game (e.g. in the note for move 33 it says that g4 would allow chances of a draw when actually it would allow a Black mate in 8 moves). Just over a year later Capablanca became world chess champion.

 

CAPABLANCA'S VISIT

COLCHESTER PLAYER'S GAME

Senor Capablanca, the Cuban chess master, writing through the manager of his tour, says that the arrangements for the exhibition at the Town Hall, Ipswich, on Thursday evening were excellent, and that he will remember his visit with the greatest pleasure. He states that he had some very interesting games.

We append below what was stated by Senor Capablanca to be the best game played against him. The finish of the game is particularly good, but the play is of interest from the commencement:-

Na3 {Although this move is forced (a privilege seldom granted by Capablanca), Black's knight remains a weakness through the whole game, and the ultimate failure of the defence is brought about by its necessary retreat to a6 on move 24.} e6 7.

Nb1 {The knight is now of little used on a3, and must come into play somehow. The move has the semblance of a trap, as the moves which follow are unusual and intricate, but the result is the loss of a move for black and a weak queenside. Such a move as Nb1 would not be played by Capablanca unless something definite lay behind.} e5 18. fxe5 Nxe5 19. Nxe5 Bxe5 20. Nd2 Bf6 21. Nf3 Rfd8 22. Re1 Qf8 23.

Rxe8 Qxe8 27. Re1 Re7 28. Qxb7 {A brilliant coup, inaugurating the final breakthrough. There appears to be nothing better for Black, as Ne5 was threatened.} Rxe1+ 29. Bxe1 Bxd4+ 30. Kf1 Nc5 31. Qxa7 Be3 32. b4 Qd8 33. Ne5 {g4 would have allowed chances of a draw, but this move is also part of the combination.} Qf6+ 34. Ke2 Ne6 35. Qb8+ Nf8 36. Qxf8+ {And wins, for 36.Kxf8 37.Nd7+ Black king moves 38.Nxf6, and Black has still his bishop en prise. A good example of the skill with which Capablanca takes advantage of small weaknesses, gradually accumulating, until the resulting decisive move is possible.} 1-0

Another two matches

Two matches were played this week, another two matches next week. The B and C teams both won 3.5-0.5, against Wethersfield and Chelmsford C respectively. The results mean that the C team still have promotion from Division 3 in their own hands and, if the A team and Maldon B slip up, the B team could still win Division 2.

Georges Koltanowski

Georges Koltanowski was a Belgian (later American) chess player who was one of the top European players in the 1930s.

He was a regular in the top tournaments and had many big-name scalps. Below is a game from the 1936/37 Hastings tournament where he drew with (and probably should have beaten) the eventual winner, former (and future) world champion, Alexander Alekhine.

So why is there a game from Georges Koltanowski on a website about Colchester Chess Club?

While Koltanowski (often called Kolty) was a very strong player, he was most famous for his incredible feats of blindfold chess. Georges Koltanowski set a world record on 20th September 1937, in a 34-game simultaneous match in Edinburgh, when playing blindfolded he won 24 games and lost 10, over a period of 13 hours. This remained the world record until November 2011. He also set another blindfold record in 1960 when be played 56 consecutive blindfolded 10-second per move games - winning 50 of them.

As part of a tour of the UK, Kolty visited Colchester Chess Club On the 24th March 1937 and gave a blindfold simultaneous display. He played 6 games - winning five (against Dr L S Penrose, Dr R C Turnbull, Councillor A H Cross, Mr R Garside and Mr E Dowsett) and drawing one (against Mr B Grey). After the simultaneous display he gave a short lecture containing anecdotes about his career and chess problems. The write-up about the event mentions that he showed himself to be an expert in the Colle system - he later wrote a book about this opening which he often used against amateur opponents (but rarely against strong players).

Kolty returned to give a second blindfold simultaneous display at Colchester Chess Club on the 29th January 1938. This time he played eight games - seven wins (against Cross, Turnbull, Stanley & Grey, Penrose & Krumpach, Hucklesby, Simmons, Garside & Sainsbury) and one loss (Rossiter & Spurge - playing together). After the simultaneous match he gave a short lecture about the Colle system - perhaps a specific request following his previous visit.

The signed picture of Kolty, above, was dedicated to Lionel Penrose (the match secretary at the club at that time).

Many of Kolty's relatives died in the holocaust, but Kolty survived as at the start of the 2nd World War he was touring South America. The American consul in Havana saw him giving a chess exhibition and decided to give him a US visa. He stayed in America where he wrote over 19,000 chess columns for the San Francisco Chronicle over a period of 52 years, he also became president of the United States Chess Federation. Unusually for a non-world class player, he made his living from chess - giving exhibitions and writing numerous books. He died in 2000 aged 96.

Further details about Kolty's visits to Colchester can be found in the scanned historical archives on the About the Club page.

Sacrifice

Here is the game played on Board 1 in the recent Colchester A v Wethersfield match. An interesting (though, according to the computer, dubious) sacrifice by Black on move 19 leads to a complicated game that White fails to find the right path through. Annotations by the winner.

I’m playing black; watch out for a couple of unnecessary mistakes I make in the middle!} 1. d4 Nf6 2. Nf3 d5 3. b3 {An unusual move that leads to easy equality for Black, who can now treat the game as a reversed Queen’s Gambit Declined.} Bf5 4. e3 e6 5. Be2 c5 6. O-O Nc6 7. a3 {Unnecessarily losing time, as Nb4 is not a threat. White should really seek to play c4 at the first opportunity to make sense of b3.} Bd6 8. Bb2 cxd4 9. exd4 {This exchange provides an edge for Black due to the misplaced bishop on b2.} O-O 10. Nh4 Be4 11. Nd2 Qc7 12. h3 Rac8 13. Rc1 {This was the last opportunity for White to play c4, as the pawns on the queenside are now becoming a liability.} Qe7 14. b4 {Ra1 was better, maintaining a more flexible pawn structure, though understandably White does not want to concede that Rc1 was inaccurate.} Bf4 15. Nhf3 Bg6 16. g3 Bh6 17. Ra1 Rfd8 18. Nh4 {After some piece-shuffling Black has emerged from the opening with a decent advantage. However, Black now attempts to force the issue…} Bxc2 $6 {A tempting move given the positions of Black’s rook on c8 and knight on c6, together with White’s awkwardly placed minor pieces on the 2nd rank and weak queenside. But Black has miscalculated…} 19. Qxc2 Nxd4 20. Qd1 {20. Qd3 is equivalent} Nxe2+ $2 (20... Rc2 {is better, after which Black can claim compensation after} 21. Bxd4 Rxd2 22. Bxf6 Qxf6 23. Qe1 Rc8 {However, 20...Nxe2 was based on a poor evaluation of the next move.}) 21. Qxe2 Rc2 $4 ({Instead, Black does better to bail out with} 21... Bxd2 22. Qxd2 Ne4 {and attempt to draw. Fortunately, White misses the winning move.}) 22. Bxf6 $2 (22. Nf5 {forking the queen and bishop is simply winning for White, though easy to miss because of the pinned e6 pawn.}) 22... Qxf6 23. Rad1 Qb2 24. Nhf3 {Black has (somehow) come out well, tying up White’s pieces with better piece activity. However, rather than the simple Qxa3 with three pawns for the piece, Black wants more… } e5 $2 25. Qxe5 $2 {Black once again relies upon White missing the key move. 25. Qd3! is significantly better for White, if not winning, as e4 is simply met by 26. Nxe4, due to the loose rook on d8.} Qxe5 26. Nxe5 Bxd2 {Black enters the endgame a pawn up with strong winning chances.} 27. Nd3 g6 28. Nc5 b6 29. Nb3 Bc3 30. Rd3 Bb2 31. a4 {Nd4 offered better chances to hold, forcing – at some point – a trade of knight for bishop. Now White’s pawns are weak, and with the passed d-pawn Black should be able to grind out a victory.} Rc4 32. Rb1 Bf6 33. Nd2 Rc3 34. Rb3 Rxd3 35. Rxd3 Kf8 36. Kf1 Ke7 37. Ke2 Ke6 38. Re3+ Kd6 39. Rd3 Re8+ 40. Kd1 d4 {Black could have advanced this pawn much earlier (e.g. move 27)} 41. f3 $2 {A move that significantly weakens White’s position, making Black’s job much easier; Rf3 offered more hope.} Kd5 42. Kc2 Be5 {Re1 is also strong, if not stronger.} 43. Nb3 Rc8+ 44. Kd2 Rc4 45. f4 Bg7 {Bd6 is perhaps better, but Black wants to keep constant control of d4.} 46. a5 Rxb4 47. axb6 axb6 48. Ke2 f5 49. Kd2 Ra4 {A simple manoeuvre that further activates the rook.} 50. Nc1 Kc4 51. Kc2 Ra1 {White’s pieces are now completely tied up.} 52. Rd1 d3+ $1 {A nice move to secure the win. Neither piece can take the pawn because of the overloaded king.} 53. Nxd3 Rxd1 {Note that the bishop covers the b2 square against the knight.} 54. Ne5+ Bxe5 55. Kxd1 Bd4 56. Kc2 b5 57. g4 b4 58. gxf5 b3+ 59. Kb1 gxf5 60. h4 h5 {Overall, not a bad game. After a well-played opening, the Bxc2 sacrifice, while objectively not great, offered some serious initiative that led to a winning endgame. However, patience is key! Sometimes the simpler move is the wiser move, maintaining advantages rather than seeking for more than the position offers. While flashy moves can feel good to play, putting your opponent in the hot seat and often providing good practical chances, they are rarely the best moves on the board. In the middlegame especially, it is normally a better strategy to calmly improve your position and wait for better opportunities to capitalise. But then, who can refuse playing a sacrifice!} 0-1

Nxc3 {I thought I'd include this game to complete the comment I made in one of my other games about people shunning dynamic play in the Morra.
