Surprising move

Denton B team fixtures in Stockport League 2

Picture: NxP, PxN, QxP, and the mate threat and possibility to swing the rook across gives black a substantial advantage.

I am waiting for the Stockport League fixtures secretary to publish a nice little spreadsheet with a summary of matches for all the teams. I’d love a list which had the Manchester League fixtures merged in, but I’m beginning to think I’ll be lucky to get anything at all.

My game in Yorkshire League

Enjoy!

Stan meets Sidonia

Sidonia is my chess engine. I took her into the chess club today and fired up my laptop. Stan takes his time when playing, but I set Sidonia to a fixed time of 15 seconds per move. I don’t remember how long Sidonia’s total thinking time was for the game, but at 4 moves per minute, it wouldn’t be hard to calculate. Stan spent more than an hour and a half on the game.

The truth really is that I cheated. I had turned on pondering. I didn’t want to be embarressed by a defeat. Pondering is a feature in some chess engines where the program will continue to think when it is not the engine’s turn to play. For a competition between two computers, pondering is fair game. For a competition between two engines on the same computer, pondering is effectively stealing processing time away from your opponent. Anyway, I turned it on, so the longer Stan thought about his moves, the better prepared Sidonia would be with her reply.

At the start, things were level. Then the game swung in Stan’s favour. Then Stand made a mistake and the game was back to level. Whatever Sidonia has seen to give Stan an advantage, we didn’t see it. The Sidonia inched away at things slowly gaining a better and better position and went on to win.

This is the game. I have analyzed it yet with a better engine to see what moves Stan and Sidonia missed.
I classified the game as friendly. Can you be friends with a computer?

Manchester Chess League – Division A

3Cs 1 & 2, Bolton, Chorlton, Denton, Great Lever, Heywood, Marple, Stockport, Urmston

Tim: It’s going to be a tough season in the Manchester League.
Just one more strong player and I will be confident,
and a bit of strength in depth.

Ivan: What are we aiming for, just to stay up?

Tim: In Manchester league defintely, it’s so strong.

Ivan: Do you think it will be harder than last year then?

Tim: Yeah. Bolton 2 and chorlton 2 went down;
up came urmston 1 who have an FM and Tong.
And Marple with Fernandez!

Ivan: So you are saying the teams up are stronger than the teams
that went down.

Tim: Yeah definitely.

Ivan: Marple were already up – they are not a concern because
they beat us every time.

Tim: The teams we need to beat to stay up are 3c’s, 2 Great Lever and Chorlton.
Anything else is a bonus.

Ivan: Hmm, I dont know how many wins are required to stay up.
How many relegated? 2?

Tim: 2 yeah.
We stayed up with 1 win and 2 draws, which is 2 wins,
but only on points difference.
I am targetting 5 points.

Ivan: How many teams are there in MCR league top division?

Tim: Quite a few: 3Cs 1 & 2, Great Lever, us (Denton), Bolton, Marple,
Urmston, Stockport, Chorlton

Ivan: 9 then with us?

Tim: Yeah, all strong teams.
Great Lever are weakest but even they are strong:
Surtees on 1, then loads of 150’s 160’s and 170’s,
but if there’s players missing they put 120’s and 130’s out.

Tim: Drat, we missed out Heywood.

Ivan: So there are ten?

Tim: Yeah 10.
Heywood is the one I forgot.

Ivan: Wow, that’s a lot. In the Stockport league they argued about 7.

Tim: You only play each other once in this league though.

Laszlo black to play pic

Tactics – Black to Play

I was looking at a few of Laszlo’s games and I rather liked a move here.

In old notation, QxQ, BxQ, BxP.
It is the BxP move that I liked, If white replies KxP then black pawn forks the king and bishop and the passed pawn queens. If not, then he’s up another pawn and the win becomes easier.

For a change I’ll give the game as PGN text instead of inserting it into the blog as  interactive graphics.

It seems I confused two chess players.

Stockport League pic

Stockport League Participants

I went to the fixtures meeting yesterday and made a note of which teams were playing in which division. The picture shows some information from my notes: how many teams each club has in the league and which division the teams are competing in. What amazes me is Marple. How can there be so many chess players in Marple?

Maybe it is because they have the best player, Fernandez. Maybe they have the best looking. Or maybe they have the best administration. One of their team organized the fixtures for Wilmslow because Wilmslow want to run a Stockport League team, but could not get anyone to the fixtures meeting.

I handed in a copy of the fixtures I had arranged for Denton 2 to a fixtures secretary. I am hoping that a spreadsheet will come back with a nice picture in that I can put on the website. Ideally the Stockport League data and Manchester Chess Federation data need to be merged and put on the site. I am not looking forward to that.

A game from Phil Boyd

Your observations regarding hxg versus fxg triggered one of my memories regarding
opening the g file.
I used to have a handhelp chess computer – Novag – and the only way I could get one over
on it was by opening the g file and getting the rooks lined up on it.
Here’s a game against Alex Longson, currently graded 216 from that era.
The game took place on 22-1-95 at the GMCCA Winter Congress, when he would have
been 12. I remember being quite chuffed when the g file opened up.
In general when you get BxN on f3, I guess the correct reply is QxB, but I’m still
tempted to do gxB opening up the file.
In the attached game I didn’t have that choice.

So who is white and who is black Phil? I guess you were white since you said you had no choice about the recapture, and I’ve edited your names into the PGN above.

Tier Two Trophy

Tier Two Trophy – Baby Cup – 2nd Tier Cup

There was a draw for another cup. I think someone wanted to call it the Tatton Cup in memory of a chess club that folded. I thought that was a good idea, but people seemed happy to drift along with a fairly nameless prize. Dave Holt wanted to call it the Dave Holt cup.

At school my father got clouted when asked about alliteration and replying “the cat crept into the crypt crapped and crept out again”. I somehow thought of this knockout competition as the “Tier Two Trophy”. It seems I prefer alliteration too, rather than the name “Second Tier Cup”. But neither is really good. A team should not compete to win something which makes them sound second rate.

Drat!
I just realized I could have written Altrincham into the semi-finals already. Well, I am not going to redo the diagram tonight.
 

Charley Cup draw pic

Charnley Cup Draw

Tonight we had the Stockport League fixtures meeting. It’s the first time I’ve been to a fixtures meeting, and I hope my last. I will explain the events in another post maybe, but one of the things that happened was the draw for the Charley Cup. I have not the faintest idea what that cup is about, but I noted down the results of the draw and now I’ve drawn it.

I’ve gone a bit mad with colours, but it took so long to get the diagram thin enough (I hope) that I coloured it bizarrely for a bit of fun.
