North Wales Championship (Round 1)

John Shakespeare Vs. Jim Grange
Gwynedd Champs, Rd. 1




This game was the first round of the local county championships. The year before I crashed out after a painful first round defeat. It was even more painful as the year before I had finished 2nd, so I had high hopes. This year I was feeling confident, but I was paired with J. Shakespare in the first round, who is also a member of Bangor Chess Club. We had played quite a few serious games before this one, and he had one every one. We trained together over the summer of 2008, and this was our first serious game since. I learned a lot about his play during that summer, and I went into this game feeling quite confident.

1)e4 e5 2)f4 Bc5 3)Nf3 d6 4)Bc4 Nf6 5)d3 Nc6 6)Nc3 Bg4 7)Na5 0-0!?




This is quite an interesting move, and one my opponent told me he was not expecting. He had prepared for 7)...Bb6, which is quite tepid in comparison. The idea of the text is to try and capitalise on a slight lead in development, which should compensate for the loss of the Bishop pair. The resulting pawn structure for Black is actually quite dynamic, with a few tactical possibilities hidden within it. I have had this position a few times, with a very healthy score. 8)Nc5 bc5 9)Bd2?!N 9)0-0 is better, after which Black continues in similar lines as to the game, but whites king is safe. ...Qd6! 10)0-0 Bf3!? of course, not a bad move, but 10)...Ne4! would have won a pawn on the spot. Now the disadvantages of whites 9th are manifest. 11)Qf3 b5!

This move is a great example of the dynamism in Blacks structure. Of course, white can't capture on b5 due to ...Nd4! winning the bishop. Additionally, white can't play 12)Bb3 really, as he then faces ...c4 13)dc4 bc4 and now must decentralise his Bishop with 14)Ba4 [14)Bc4? Qd4+ winning the Bishop]. Therefore, white has to relinquish his Bishop pair, possibly his only positional advantage. Black has the initiative, and is slightly better. 12)Bd5 Nd5 13)ed5 Nd4! 14)Qf2 Nc2 Black is a clear pawn up for no compensation. 15)Rc1 Nd4 16)fe5 Qd5! This is the better pawn to capture, retaining the black pawn at c5. White still has the e5 weakness, so it won't be going far. 17)Be3 Qe5 There it goes! 18)Kh1 I am not sure now why he played this move. At the time of the game I was actually expecting it as there were some lines where a king on g1 was problematic. I can't at this time notice what the problem was. That is probably a good indication we were both seeing things! ...Rae8 19)Bf4 Qd5 20)Be3 c6 This felt like an important move at the time. If white exchanges on d4 as things stood, the c7 pawn was hanging and white would get some nice activity. 21)b3 I really think 21)b4 is whites only chance to fight for some complications here, trying to loosen blacks knight on d4.

This move is critical, and blacks only way to retain the advantage is with 21)...Re3!! which I felt was easy to spot, and was planning it as I was convinced white would play b4. 22)Qe3 cb4! again, the only move. Now black has two pawns for the exchange, a dominating knight & Queen, and a queenside majority ready to roll. Black is winning in that position. 21)...Re6 with the obvious plan of harassing the Kingside. 22)Rc5?? Qc5 23)Bd4 Qd5 White resigned. There are no tricks. White was planning 24)Bc5 which appears to give back the exchange thus winning back a pawn. The resulting heavy piece ending is likely drawn. However, white had overlooked 24)...Rf6! winning.

A good start to the championship. At the end of this game the pairing for round 2 was drawn, and I was paired with a FIDE 2100 player. I will post that game in a few days time.

2007 Gwynedd Championships

Well, I have not updated here in a while, so let me return with 5 games from the recent Gwynedd (North Wales) Championship, which I came second in. It was a Swiss tournament, with only about 22 players in, but the competition was quite strong. I finished on 4/5, unbeaten, which I was quite pleased with. However, I of course felt that I could (and should) have won. This was the first game of the championship, against a chap from Llandudno, just down the road. I had black, and had prepared a novelty against a move I knew he would play. I was very pleased with this game, but unfortunately I have since lost the game sheet, so the following is not the whole game, just what I can remember.

Gary Fox Vs Jim Grange. Gwynedd Championship, Round 1.



1) e4 e5 2)Nf3 Nc6 3)d4 ed4 4)Nd4 Bc5 5)Be3 Qf6 6)c3 Nge7 7)Bc4 Ne5 8)Bb3?!

This is the move I was counting on Gary playing, and I'm not sure why I was convinced he would play it. The correct move is 8)Be2. I had the afternoon to prepare for this game, and spent the whole time looking at the consequences after this Bb3. I could not find anything useful in my database, so searched the position with Fritz. I found a nice pawn sacrifice, with all variations leading to a small plus to black, and MANY pitfalls leading to a quick loss for White. This was a very pleaseant position to be in, knowing full well I just had to remember my analysis. I did. 8)...Qg6! 9)O-O d5!! Novelty.

This is the sac, which is just crushing. If you are expecting me to reprint all my analysis here, you are sadly mistaken :) I have used my analysis for quick wins twice since this game, and I plan to continue to do so, so no secrets going to be shared here! 10)Nb5?? OK, I will share one secret with you: this move is not best :) 10)...Bh3! 11)g3 Qe4! 12)Nc7 Kd7! Please excuse all the exclamation marks, but they are all great moves! Black is totally winning, but White finds a nice way to bring an ending. The moves are also quite forced! 13)Bd5! Nd5 14)Qd5 Qd5 15)Nd5

It seems that White is fighting back, but the realisation sets in with the next move: 15)...Nf3! 16)Kh1 Bf1 17)Bc5 Kc6! 18)Ne3 Kc5 19)Nf1

White resigned a few moves later. What is amazing is that I had this exact position (and variations arising from it) on my board in my office earlier that day whilst analysing the novelty 9)...d5!! Therefore, all I had to do was to remember my analysis. A great start to the tournament! I won game of the week for this effort.
