GAME 006 - VS Kier Eyles

Kier Eyles VS Edward Davies - 15th November 2006 Portsmouth Individual

1.d4 c6 2.c4 d5 3.e3 Unusual move order. 3...Nf6 4.Bd3 [More common is 4.Nf3 or; 4.Nc3] 4...e6 I play a semi-slav. Several tenable 4... options existed. I think most interesting is 4...e5 [4...e5 5.Nc3 e4 6.Bc2 Bd6 7.Nge2 0–0 8.Bd2 Nbd7 9.Ng3 Re8 10.Qe2 a6 from a game.; 4...Bg4 5.Ne2 (5.f3 Bh5 6.cxd5 cxd5 7.Qb3 Qc7 8.Nc3) 5...e6 6.Nbc3 Nbd7 7.0–0 Bd6 8.f3 Bh5 9.e4 dxe4 10.fxe4] 5.Nf3 Everything soon transposes into main lines. 5...dxc4 [5...Nbd7] 6.Bxc4 By far most common in this position is c5. 6...Be7 Not very ambitious [e.g. 6...c5 it seems this freeing pawn move is important in this type of position, even at the cost of a move 7.0–0 a6 8.Bb3 Nc6 9.Nc3 cxd4 10.exd4] 7.0–0 0–0 8.Nc3 Nbd7 [8...b5 9.Bd3 b4 10.Na4 Ba6 11.Ne5 Bxd3 12.Nxd3 Nbd7 13.Bd2 a5; 8...c5 9.dxc5 Bxc5 10.Qc2 Qc7] 9.Qe2 [9.e4 c5 10.dxc5 Bxc5 11.Qe2] 9...b6 This time, VERY unambitious. This shows a lack of confidence in this sort of position. [9...b5 suggests itself, and from a master game: 10.Bd3 b4 11.Ne4 c5 12.Nxf6+ Nxf6 13.dxc5 Bb7 14.e4 Now the game has transposed into a positon reached a couple of dozen times; I also prefer 9...c5 10.dxc5 Bxc5 11.e4 but white is still better] 10.Rd1 Bb7 11.e4 Re8 This really isn't the way to continue. I need to address the space problem, e.g. with 11...c5. [11...c5 12.Bg5 cxd4 13.Nxd4 Qe8 14.Bb5 a6 15.Bc6 Black's position is still unpleasant.] 12.e5 Definitely not the strongest continuation. Fritz drops the evaluation from about 0.8 to 0.3. [12.Bg5 Qc7 13.Rac1 Qb8 white is given a pawn advantage by fritz] 12...Nd5 13.Ne4 h6 14.Bd2 Not the most energetic continuation. [An (unforced) example line: 14.Ne1 Nf8 15.Qh5 Qd7 16.Rd3 Ng6 17.Rg3 a5 18.Rxg6! fxg6 19.Qxg6] 14...a5 15.Rac1 According to fritz, white has just a slight edge circa E0.3 15...Rc8 [an alternative: 15...a4 16.a3 Rc8 17.g4 f6 the computer takes a long time in such positions] 16.Bd3 Nb4 Fritz isn't keen on this at all. Partly due to specific lines, partly due to the knight being less strong here than central d5 maybe. [an alternative: 16...a4 17.Nc3 Nb4 18.Bb1 a3 19.bxa3 Nd5 White is still given a strong advantage. I have noticed the evaluation can shift unexpectedly in these late opening positions of the slav.] 17.Bb1 Understandable, but white just has a slight advantage with this. [17.Bxb4 This is a critical continuation. 17...Bxb4 18.Nfd2 f5 19.exf6 Nxf6 20.Nc4 white is given a big advantage] 17...Ba6 Logical continuation. 18.Qe3 [or 18.Qe1 ] 18...Nd5 19.Qe1 With this additional passive move, white has good as lost his advantage. 19.Qb3 was the active move. [19.Qb3 c5 20.dxc5 Nxc5 21.Nxc5 Bxc5 22.Be4 Retaining a slight advantage.] 19...Nb4 Fritz isn't impressed with this move. [19...a4 20.Nc3 a3 21.Nxd5 exd5 22.b4 The position is supposedly about equal. 22...Nf8 23.Qe3] 20.Bf4 Nd5 21.Bg3 c5 BAD. Looks good but fails under analysis. [21...Bb4 is good 22.Nfd2 a4 23.a3 Be7 DSB must stay on a3-f8 to counter Nd6] 22.Nc3 Not the critical continuation. [22.dxc5 Nxc5 23.Nd6 Bxd6 24.exd6 Qd7 the strongest continuation according to fritz 25.Ne5 Qb7 26.Qd2 Red8 27.Qd4 Be2 28.Re1 Bb5 29.Qg4] 22...Nxc3 23.bxc3 cxd4 24.cxd4 [fritz prefers 24.Nxd4 e.g. 24...Qc7 25.Qe4 Nf8 26.Qg4 Bc4 27.a4] 24...Rxc1 [alternatively 24...Bc4 25.Qe4 Nf8 26.Nd2 Bd5 27.Rxc8 Qxc8 28.Qg4 b5] 25.Rxc1 Bb4? This is a superficial, and after the queen moves, the bishop is offside on b4 compared to its original square e7, and also the white queen has moves to a better square. Therefore this is a positionally rubbish move. [25...Bb7 as my opponent suggested, reposting this bishop on this diagonal makes sense. This also prevents a Q-B battery byQe4] 26.Qe4 f5? This crude counter of the white Q-B battery probably objectively costs the game. Nf8 was the correct move. It is interesting that in only a slightly worse position, one poor positonal move leading to waste of time and misplacing of a piece is then immediately followed up by an outright positional blunder due to the pressure the initial bad positonal move put the black position under. Sensible defence was called for here and there would have been much better chances of a sober defence. [26...Nf8 27.Qg4 Bb7 28.Bd3 Qd7 29.Bh4 Rc8 The defence is quite successful and the black position is still intact.] 27.exf6 Nxf6 28.Qg6 Bb7 After this, white has a crushing position. The best attempt to hold the position was 28...Bd6 [28...Bd6 29.Ne5 Rf8 ...] 29.Ne5 This misses a killing continuation; Bh4 [29.Bh4 Bxf3 30.Bxf6 Qxf6 31.Qxe8+ Bf8 32.Rc7 (not 32.gxf3 Qg5+ 33.Kh1 Qxc1+) 32...Bd5 33.a4 e5 34.dxe5 Qe6 35.Qh5] 29...Rf8 30.Bf4 [30.Ng4 Qxd4 31.Nxf6+ Rxf6 32.Qh7+ Kf7 33.Rc7+ Ke8 34.Qg8+ Bf8 35.h4] 30...Qd5 [30...Qe8 this is much better, e.g.: 31.Qg3 Nh5 32.Qd3 Nf6 33.Bxh6 Qh5 34.Bf4 Nd5] 31.Bxh6 [31.Bd3 b5 32.a4 Qxg2+ 33.Qxg2 Bxg2 34.Kxg2 Nd5 35.Bg3 bxa4 36.Rc6 Re8] 31...Qxg2 + (DIAGRAM) initiates forcing sequence 32.Qxg2 Bxg2 33.Bxg7 Kxg7 34.Kxg2 I feel that in this ending, black has good hopes to hold if he plays well. [It would have been better to interpose 34.Rc7+ for example: 34...Kg8 35.Kxg2 Bd6 36.Rc6 Bxe5 37.dxe5 Nd5] 34...Bd6 Not the best. [34...Nd5 35.Be4 Rf4 36.Bxd5 exd5 37.Nc6 Bd6] 35.f3 Not the most direct continuation. [35.Rc6 Bxe5 36.dxe5 Nd5 Making use of the resource Rxd6?? Nf4+ 37.h4 (37.Rxe6?? Nf4+) 37...Nf4+ 38.Kf3 Nd3+ 39.Ke2 Nf4+ 40.Kd2] 35...Bxe5 It's worth ng that in this ending, both players only have a few minutes left to make a several moves. [35...Nd5 36.Be4 b5 37.Kf2 Bxe5 38.dxe5 b4 39.Bxd5 exd5 40.Ke3 Rh8 41.Rc2 Very bad rook ending for black.] 36.dxe5 Nd5 Not too bad. Importantly it also stops the invasion Rc7+ [36...Nd7 attacking e5 and maybe heading for c5, and also preventing Rc7+ 37.Re1 b5 38.Re4 b4 39.Rg4+ Kf7 40.f4 a4 Black is correctly using his pawn majority on the q-side for counterplay 41.h4 b3 42.h5 Rh8 43.axb3 axb3 44.Rh4] 37.Kf2 [37.Be4 A perfectly good alternative.

An obvious blunder. From now on the position is unsalvagable. I think I was unaware that until this point I had good reason to play for a draw.

Adrian Waldock VS Edward Davies - Hastings Minor 2006/7

1.d4 c6 2.e4 d5 3.Nc3 dxe4 4.Nxe4 Bf5 I have chosen - somewhat arbitrarily - to use the classical line of the caro-kann as opposed to 4...Nf6 or 4...Nd7 systems. I'm happy with this choice but need to study all the various move orders in some detail now that I've adopted it in my repetoire. 5.Ng3 Bg6 6.Nf3 Sadly I was somewhat thrown even by such a minor difference in move order. I will have to work hard on this system, (and all of my repetoire) looking at deviations in move order. [6.h4 This is the normal move order. 6...h6 7.Nf3 Nd7 etc] 6...h6?? I played this inferior move thinking at the time it was the only choice. I feared that after 6...Nd7, Nh4 would occur, forcing the 'unfavourable' trade of my bishop for his knight. I will look into this line. 6...Nd7 is indeed the standard move. From here on, considerations of the opening will not be of interest to me and I will just look at middle-game concepts etc, as I will obviously never see this again unless it's played against me. I will take a last look at the best ways of capitalising on this slow 'ghostbuster' move. As for the ??, I feel this is a strong enough opening blunder to warrant it. After white's critical reply, (Ne5), black has a losing position whatever happens. [The correct move. 6...Nd7 What of independent lines? (7.h4 transposing back into the main line) a) 7.Bd3 e.g. 7...Ngf6 a1) 7...e6 8.0–0 Ngf6 9.c4 Bd6 10.b3 0–0 11.Bb2 c5; a2) Not 7...Bxd3 as was incidentally played AGAINST me by John Sowerby in the same event (Hastings 2007) [which was drawn but with the better chances for white]. Fritz considers this move inferior. 8.Qxd3 Ngf6 9.Bd2 e6 10.0–0–0 (10.0–0 c5 11.c4 cxd4 12.Qxd4 Bc5 13.Qc3 0–0 14.b4 Be7 15.Rfd1 Qc7 16.Rac1 Rfc8 17.Nd4 Nb6 18.c5 Nbd5 19.Qb3 Qd8 20.c6 bxc6 21.Nxc6 Qf8 22.Nxe7+ Qxe7 23.a4 h6 24.b5 Qb7 25.Ne2 a6 26.Nc3 Nxc3 27.Bxc3 Nd5 28.Bd4 axb5 29.Rxc8+ Rxc8 30.Qxb5 Qc7 31.g3 Rb8 32.Qc5 Qxc5 33.Bxc5 Ra8 34.Ra1 Ra5 35.Bd4 f6 36.Be3 Nxe3 37.fxe3 Kf7 38.Kf2 Ke7 39.Ke2 Kd7 40.Kd3 Kc6 41.Kc4 Kb6 42.Rb1+ Ka6 43.Ra1 Re5 44.Kd4 Ka5 45.e4 Rg5 46.Ra3 f5 47.exf5 exf5 48.h4 Rg6 49.Ke5 Rf6 50.Rf3 Kxa4 51.Rxf5 Rg6 52.Kf4 Rb6 53.Re5 Rc6 54.g4 g6 Edd Davies - John Sowerby (Hastings 2007) in which I should have played on to try and win due to superior king position, but which I too sportingly agreed to a draw (after my opponent's confusion about the digital clock). One of the changes in my game I have learnt from the Hastings tournament is to play on almost (or literally) to the end in endgames as there is still scope to win technically or ostensibly drawn endings.) 10...Be7 11.Kb1 c5 12.Ne4 0–0 13.Nxf6+ Bxf6 14.h4 cxd4 15.Ng5 g6 16.Nxh7 Kxh7 is the only example in the Fritz database ( + - ); 8.0–0 e6 9.c4 Bd6 10.b3 0–0 11.Bb2 c5 12.Bxg6 hxg6 13.Re1 Qc7 14.dxc5 Bxc5 15.Qc2 Rfd8 16.Ne4 Nxe4 17.Qxe4; b) 7.Nh4 This is0 the move I feared and thought necessary to sidestep. There is only one example in the database and it lost. 7...Ngf6 (7...e6 8.Nxg6 hxg6 Also perfectly ok for black. 9.Be2 Ngf6 10.c4 Bb4+ 11.Bd2 Qb6 12.0–0 Bxd2 13.Qxd2 0–0–0 As indicated by these two linse, it is natural for black to castle q-side after hg.) 8.c3 (8.Nxg6 hxg6 This isn't a problem for black.) 8...e6 9.Be2 Bd6 10.Nxg6 hxg6 11.Qd3 Qc7 12.Ne4 Bf4 13.Nd2 0–0–0 14.g3 Bh6 15.Nf3; 7...h6] 7.Bd3 Not as strong as 7.Ne5 but still strong circa E1.1–Fritz [7.Ne5 The critical refutation.

Bf4 is a better place to put the bishop. Fritz recommends 9.0–0 [9.0–0 e6 10.Bf4 Bd6 11.Be5 Bxe5 12.Nxe5 0–0 13.f4 And black is under tangible presssure but is not losing yet.] 9...Nbd7 Perhaps slightly inferior to the developing move 9..e6, presumably preparing k-side castling. I was of course preparing q-side castling. [9...e6 10.0–0 Bd6 11.c4 Nbd7 12.Rfe1 Qc7 13.a4 0–0 This looks the safest, but instead, Fritz prefers to go in for QSK (13...0–0–0 14.Rab1 Bb4 15.Bd2 Bxd2 16.Qxd2 h5 ...) 14.Ne4 Bb4 15.Re2 Rad8 16.Rd1 In either case, white is better, (due to his lead in development afforded by the pawn move 6...h6)] 10.0–0–0 Fritz drops white's evaluation to just a 1/4 pawn [10.0–0 F(1) (fritz's 1st choice)] 10...Qc7 [10...e6 is better. 11.Bf4 Be7 12.Kb1 0–0 13.Rhe1 Qa5 14.Ne5 And black isn't doing too badly. 14...Rfd8 15.Qe2 Nxe5 16.dxe5 Rxd1+ 17.Rxd1 Nd5 18.Bd2 Qc7] 11.Rhe1 [11.Qb3 e6 12.Ne5 a5 13.f4 a4 14.Qd3 a3 15.b3 Be7 16.Nxd7 Qxd7 17.f5 0–0–0 This is an interesting position where white is slightly better.] 11...0–0–0 [F(1): 11...e6 12.Kb1 0–0–0 13.c4 Bd6 14.Ne4 Nxe4 15.Qxe4 Nf6 16.Qc2 Where white is a little better.] 12.Kb1 [12.Qa3 a6 (12...Kb8? black comes under heavy fire 13.d5 a6 14.dxc6 Rc8 15.Qa4 Qxc6 16.Bf4+ Ka8 17.Qxc6 bxc6 18.Ne4± Black's king cover is broken, his pieces less active and less developed, and his pawns weaker. Quite a list of defects!) 13.c4 e6 14.Qb3²] 12...e6 13.c4 Fritz assesses this position as a very slight plus for white, but about equal, so I have managed well in the opening after my shaky start, (and my opponent's advantage has dropped from a potential E2 to about E0.2) 13...Kb8 14.Re2 According to Fritz, the position is very nearly equal [14.Ne2 Bb4 15.Bf4 Bd6 16.Bxd6 Qxd6 17.Nc3] 14...Bd6 15.Rc2 The first time in the game the evaluation has shifted (but only marginally) into black's favour.

I probably felt I should do something about my knight on e2, but it is clear that this could be an important defensive piece and I am doing my opponent a favour by trading it with his inactive knights. 20.Qb3 [F(1): 20.Qe2 Ng6 21.c5 Qb5 22.Qc2 Qa6 23.a4] 20...Nxf3 =F(1) [At first fritz suggested the depressing 20...Ng6 e.g. 21.c5 Qa6 22.a4 b5 23.cxb6 Qxb6 24.N1d2 Ka8 25.b5 cxb5 26.axb5± How black wishes the knight was still on e2 for defence!] 21.gxf3 Nf6 It's unavoidable that white now has a lingering advantage, due to his space and pressure on the kingside. Black has a difficult defensive task ahead. 22.Ng3 One gets the feeling that accurate and probably dynamic defence is required of black to hold this position. White has the far easier position to play.
