The fourth team managed to keep their second division hopes alive last night by holding the Args. to a dramatic draw in spite of an overwhelming grading difference. Anthony (135) drew with Peter Farr (179) on top board and Kevin (117) beat Jim Graham (156) on board three. Joe and Arthur on boards two and four were also out-graded by nearly 40 points. We're now in a three-way fight to avoid relegation with two home matches still to go.

Brighton and Hove win Knock Out final
A grading difference of 62 meant we needed 2½ to win the match (a drawn outcome is not possible in the KO, any more than unfinished games). Knock out matches usually go to the stronger team, in spite of the grading handicap - this year's results bear this out with only one upset in seven games. So 62 grading points - we were expecting more - was still enough to wipe us out. Most of the difference was on board one where Callum took on Feliks as black with a board difference of 43. Feliks was already struggling and two pawns down when the snatch of a particularly poisoned pawn led him into a trap and his queen was cornered. Robin narrowly lost a tricky and time-pressured ending on board two with a 20 point difference. Paul S. drew on board three, Michael H. lost on four and Jan won on five. We had 2½. A great result for Callum who is fast becoming one of our strongest players.
Congratulations and thanks to everyone who's played in the KO this year. As well as last night's team that's Michael C., Terry, Rob, Mustapha and Seb (and me).
PS The results posted below from the MSCL website use last year's grades which makes the grading difference 74 (with 49 on board one), whereas the results form is preset using the January grades. Rule changes to clarify this are apparently being sought at the MSCL AGM.

Michael's draw with a grandmaster in a simul
In May 2013 Ray Keene gave a ten board simul at the Hove Club in Fourth Avenue. He won eight of these games while Sue Chadwick and Michael Cain did well to obtain draws.
Ray won the British Championship in 1971 and represented England in eight olympiads. He gained the title of grandmaster in 1976 and in 1985 was made an OBE for services to chess. He also has a strong Brighton connection and is an honorary member of our club. To date he is the only grandmaster ever to have represented the club in matches. He organised the Brighton international tournaments from 1979 to 1985 and the publicity from this may have helped our club when we were trying to stay at our premises in Pavilion Buildings. Ray has been chess correspondent of The Times since 1985 and has written over a hundred books. He is also an exceptional organiser and was involved in the organisation of the 1986, 1993 and 2000 World Championships.
I know from playing Ray on a few occasions when I was a young player that he has a highly original, hypermodern style which is difficult to cope with.
I enclose the score of his game against Michael Cain in the above-mentioned simul. Ray would of course have been under pressure to move almost immediately and it would have been difficult to calculate anything complicated. On the other hand this is another example of Michael reserving his best chess for these occasions:

Geoffrey's excellent result in British Seniors
Geoffrey James recently came second in the British Seniors at Aberystwyth with 5.5 points out of 7. This was his highest score in the competition, though in 2009 he came first equal in the event with 5 points. Geoffrey is the club's longest serving member having first enlisted in about 1960. He is at present the club treasurer, but has also carried out the duties of secretary and match captain in the past. He has won the county championship seven times and the club championship a record seventeen times. He has also made over 400 appearances for Sussex, second only to John Cannon of Horsham in county history.
Geoffrey has kindly supplied notes to his win in round 6 of the British Seniors:

Resourceful play by Michael Cain
Ezra Kirk gave a simultaneous display at the club on 21st June and did not lose a single game. He took on eleven players and was held to a draw by Michael Cain and Arthur de Silver, but defeated everyone else. In the 2012-13 season he won against grandmasters Keith Arkell and Tony Kosten to establish himself as the highest rated player in the country for his age. More recently he has played little competitive chess as he has been taking several exams. He is already a FIDE master and plans to spend a year entering chess competitions to try to become an international master before going to university. We wish him the best of luck in his quest, though he probably has the potential to become not just an international master but also a grandmaster.
I enclose the score of Ezra's game against Michael Cain in the recent simul. It is very difficult playing eleven players at the same time particularly when one is expected to make every move very quickly. However, we must also give credit to Michael for a resourceful display. Michael seems to produce his best chess in simultaneous displays as he also drew last year with grandmaster Ray Keene in this form of chess. On other such occasions he has given Nigel Short and Luke Rutherford very good games before eventually losing.

If White wants to fianchetto his White-squared bishop, it is better to play 5 cxd5 first.} dxc4 {Correct, giving Black an advantage.} 6. a4 {To stop Black playing b5. If 6 Bg2 Nf6 7 0-0 0-0 8 e4 b5 or Bg4 are both better for Black.} Bg4 {The best move is probably 6...c5 attacking the White centre. If 7 dxc5 Qxd1+ 8 Nxd1 Na6 with the better game. If 7 d5 Bxc3+! 8 bxc3 Nf6 is also strong for Black. Finally if 7 e3 Nf6 8 Bxc4 0-0 9 0-0 Bg4 is still better for Black.} 7. Ne5 {Black gets a definite advantage now. Better was 7 e3.} Bxe5 8.
dxe5 Qxd1+ 9. Nxd1 f6 {Better was 9...Nd7 and, if 10 Bf4, then f6. In this line 11 exf6 could be met with e5.} 10. exf6 exf6 {Better was the developing move 10...Nxf6 with an advantage.} 11. e4 {A mistake which loses a pawn for nothing. Better was 11 Bf4.} Bf3 12. Rg1 Bxe4 13. Bxc4 Nd7 14.
Nc3 Bf3 15. Bf4 {Better was probably 15 Be2.} O-O-O 16.

Now the game is more or less level.} 18. Bxe5 {White should have played 18 Re1 so that Black would have had to lose a tempo to break the pin by moving his king. After 18...Kd7 or Kd8 White could then have played Bxe5. This might seem similar to the game but White would benefit from his rook on e1.} Rxe5 {18...fxe5 was better and would have given Black a definite advantage. The f6 square would have been vacated for the Black knight and there was the potential to play e4.} 19. Rg3 Bd5 20.
Bxd5 cxd5 21. f4 Re6 22. Nxd5 Ne7 {The game now looks drawish.} 23. Nc3 {Possibly Ezra decided against exchanging knights as he still hoped to win the game. However, it could be argued that a Black knight on c6 would have been stronger than a White knight on c3 in this type of position.} Rd8 24. Rc1 {24 Re1 would have been more or less level.} Kb8 {24...Nc6 looks better.} 25. Rc2 {Again 25 Re1 was a safe drawing line.} Rd4 26. Rf3
Nd5 {26...a6 might have given Black an edge. The exchange of knights brings about a similar position to what might have happened if White had played 23 Nxe7.} 27. Nxd5 Rxd5 28. Rfc3 {Surprisingly this move seems to give Black an advantage as White has difficulty defending his pawns. 28 b3 looks better.} a5 {Much better than 28...a6 as it establishes a bind on White's queen side pawns and gives the Black king a little more space.} 29. Rc4 {29 b3 might still have been the best move.} h5 {Not the best move. Black could have got an advantage by 29...Rd1+ 30 Kf2 Rb6 because of the weakness of the White pawn on b2.} 30. h3 {30 f5 gxf5 31 gxh5 would have taken all the pressure off White.} h4 {Black could have played 30...hxg4 31 hxg4 Rd1+ 32 Kf2 Rb6 with perhaps a slight advantage - cf. my note to Black's 29th move. 30...h4 is a bold move with the potential for Black to seize control of the third rank with his rooks. White must now play very carefully.} 31. Kg2 {This seems to be a mistake. White should play 31 Rc8+ Ka7 32 R2c5. If then 32...Rd1+ 33 Kf2 Rd2+ 34 Kf3 Rxb2 35 Rxa5+ Kb6 36 Rac5, which looks drawish.} Re3 32. Rc8+ Ka7
33. R8c5 {33 Rf8 and 33 Rg8 both lead to complex variations in Black's favour.} Rdd3 34. Rxa5+ Kb8 35. g5 f5 36.

If 6 Bg2 Nf6 7 0-0 0-0 8 e4 b5 or Bg4 are both better for Black.} Bg4 {The best move is probably 6...c5 attacking the White centre. If 7 dxc5 Qxd1+ 8 Nxd1 Na6 with the better game.

Now the game is more or less level.} 18. Bxe5 {White should have played 18 Re1 so that Black would have had to lose a tempo to break the pin by moving his king. After 18...Kd7 or Kd8 White could then have played Bxe5. This might seem similar to the game but White would benefit from his rook on e1.} Rxe5 {18...fxe5 was better and would have given Black a definite advantage.

Bxd5 cxd5 21. f4 Re6 22. Nxd5 Ne7 {The game now looks drawish.} 23. Nc3 {Possibly Ezra decided against exchanging knights as he still hoped to win the game.

Rfc3 {Surprisingly this move seems to give Black an advantage as White has difficulty defending his pawns. 28 b3 looks better.} a5 {Much better than 28...a6 as it establishes a bind on White's queen side pawns and gives the Black king a little more space.} 29. Rc4 {29 b3 might still have been the best move.} h5 {Not the best move. Black could have got an advantage by 29...Rd1+ 30 Kf2 Rb6 because of the weakness of the White pawn on b2.} 30. h3 {30 f5 gxf5 31 gxh5 would have taken all the pressure off White.} h4 {Black could have played 30...hxg4 31 hxg4 Rd1+ 32 Kf2 Rb6 with perhaps a slight advantage - cf. my note to Black's 29th move. 30...h4 is a bold move with the potential for Black to seize control of the third rank with his rooks. White must now play very carefully.} 31. Kg2 {This seems to be a mistake. White should play 31 Rc8+ Ka7 32 R2c5.

Paul plays a captain's part.
Paul Batchelor has shown great loyalty to the club by serving as first team captain for nearly fifteen years. It is no easy job to be a team captain. Boards have to be arranged, clocks set at the correct rate, refreshments arranged and teams selected. If any incident occurs in a match, the captain has to be on the spot even if he/she is concentrating on his/her own game.
Paul is also the county U-180 captain, a post which he first undertook in 2009. As his grading is nowadays over 180, he cannot play in this team, although he still organises the players. Paul also helps Dix Roberts, the Open team captain, and plays himself in the first team. The improvement in his play is reflected in the fact that he won the Brighton CC Championship in 2010.
In the recent McArthur Cup final against Hastings Paul played a captain's part by winning on board three against Ollie Willson, a very promising junior who won the British U-16 Championship last year. Paul had a won game by about move fifteen and he did not allow his opponent to obtain any significant counterplay. I enclose the score of this excellent win

Fine win by Callum at Hastings
One might have expected that 13 year old Callum Brewer would have found the opposition daunting at his first Hastings Masters tournament, but instead he did well to score four points out of nine. His best game was in the first round, when he completely outplayed the Norwegian player, Joar Pettersen. I enclose the moves of this excellent win:

How Dona toppled a giant!
Dona Strauss lived in Hull for many years before she came to Brighton. In 1996 Michael Adams, who is one of the best players in the world, came to the Yorkshire city to give a simultaneous. Out of forty one games he lost only three, one of which was against an inspired Dona. We must make allowance for the fact that the grandmaster was taking on so many players at the same time, but Dona deserves credit for enterprising play. The game was published in the Hull Chess Club magazine (November/December 1996 issue) with annotations by club champion, Stuart Brown, but computer analysis has come a long way since 1996. I have tried therefore to update his comments. Please contact me, if you want a game published on the club website.

Nxe4 {The crucial point in the game. 20..Bd7 was playable with perhaps a slight advantage for White. Instead Dona plays a bold and imaginative move, which probably came as a great surprise to her illustrious opponent. The complex variations might have been in White's favour, but Michael would not have had the time to enter into complicated calculations.} 21. Nxe4 {A losing move.

Nc3 {Better was 10 Nd2 followed by 11 Nb3 or f3 challenging the d4 square.} c6 11. Be3 Re8 12. Qd2 {We do not know if Michael deliberately sacrificed the pawn back to gain development. White is struggling to gain an advantage because of Black's occupation of the d4 square. He could have tried 12 Qb3 b5 13 Bf3 Rc8, but Black's position was solid.} Bxe3 13. fxe3 Bxc4 14.

The knight on d5 might become a catalyst in allowing White to advance his central pawns - as actually happened in the game.} 17. R4f3 Rad8 18. d4 {White naturally tried to advance his central pawns, though they soon came under attack. 18 Rg3 might have been a little better.} c5 19. e4 Nf6 {The clearest path to equality seems to have been by playing 19...cxd4 20 Nxd5 Bxd5 21 exd5 Qxe2 22 Qxd4 f6. In this line 21 Bb5 can be met with 21...Bc6 with complex play, which is in Black's favour.} 20. d5
Nxe4 {The crucial point in the game. 20..Bd7 was playable with perhaps a slight advantage for White. Instead Dona plays a bold and imaginative move, which probably came as a great surprise to her illustrious opponent. The complex variations might have been in White's favour, but Michael would not have had the time to enter into complicated calculations.} 21. Nxe4 {A losing move. Stuart Brown in the Hull CC magazine gives as his main line 21 Qf4 Bxd5 22 Nxd5 Rxd5 23 Bc4 Nf6 24 Bxd5 Nxd5 25 Qxf7+ Qxf7 26 Rxf7 Ne3 with a draw as White has no good move for his rook on f1. Stuart does not consider other queen moves for White. 21 Qd3 loses against 21..Nxc3 and 21 Qe3 is met by 21...Bg4 22 Rxf7 Qg5 with the better game for Black, but more challenging is 21 Qc2. Black's best reply would seem to be 21..Bg4 when 22 Rxf7 Qh4 23 Nxe4 Bxe2 24 Qxe2 Qxe4 25 Qxe4 Rxe4 26 Rxb7 h5 27 Rxa7 Rxd5 28 h3 Re2 is more or less equal. More dangerous for Black is 24 Rxg7+ Kxg7 25 Qc3+ Kg6 26 Rf6+ Kh5, but amazingly Black's king cannot be mated!} Bxd5 {White is now lost in all variations and Dona mops up in convincing style.} 22.

Pretty mate by John Henshaw
John gained a vital win for the first team in our recent match against Horsham 1. This season in the Mid-Sussex League he has scored 8/9 which makes him a contender to hold the tankard for a year, which is awarded for the highest individual score in the division. Not everyone knows that John won the county championship in 1972 and regularly played on a high board for the club and Sussex for many years. He took a break from chess in 1996 and it is no coincidence that the first team has fared better in the three seasons since he returned to the game. In this game an attractive sacrifice on move 26 allows penetration on the black squares. John has kindly supplied the comments to the game.

Fireworks from Michael Hamilton
Rapidly improving Michael recently won an exciting game in the Brighton 3 v Horsham 2 match. Faced by a very experienced opponent in Peter Harbott, he sacrificed a bishop, then a rook and finally a rook for a bishop before mating the enemy king. The comments in the enclosed game are Michael's and mine and are based on computer analysis. If members of the club want a game published on the blog, please contact me.
