Today’s Chess Problem 9/19/11
My last chess problem post got a little interesting in the comments:
Chris, a little post on how the nomenclature works would benefit everyone. It’s shorthand notation, and very terse ... I find it a bit irritating because I don’t fully understand it, and I also am not happy “leaving out the final moves as an academic exercise” even when they are blatantly obvious. I’m not much of a player so that seems wrong to me somehow.
Valid points. Here’s a Wikipedia entry on algebraic chess notation.
I even found that entry a bit ‘terse’. Here’s another article, which you can download as a pdf file.
And I will make an effort to ‘play out the final moves’… even if they are, to me, obvious. I’m just used to that. Most problem books quit after a move or two because they assume if you are reading them, you’re able to find the ‘obvious’ final moves. I guess the best way to illustrate that would be to post some of MY best games. I can at least explain how I was thinking, and why my opponent resigned/accepted the draw, or why I resigned/accepted the draw.
An example is today’s problem. Yes, queen takes knight wins the game, but it isn’t ‘all over’ when that occurs. Black rook at d7 then takes white queen at c7, white rook at d1 takes black rook at d8 for another check, black rook at c7 moves to c8 to block, and then white rook at c1 takes black rook at c8 for the mate. If it goes any other way (queen takes knight, rook takes queen, then white rook at c1 takes black rook at c7) then black can not only escape but win!
Let me address that while showing the solution to the last problem.
1. Qxc7+ Rxc7
Now, if
well, guess this is one of those ‘obvious’ moves. If:queen takes knight, rook takes queen, then white rook at c1 takes black rook at c7
1. Qxc7+ Rxc7
2. Rxc7?? Rxd1+ and Black is winning.
3. Bf1 (only move) Kxc7
Black is up Q and R vs. B. And it’s all forced.
Now, ‘obviously’, White didn’t even look at such a losing move when sacrificing the Queen on c7.
Back to the solution to the last problem.
1. Qx7+ Rxc7
2. Rxd8+ Rc8 (forced!)
3. R (either White R) xc8 mate
Today’s Problem:
1. ?
That’s chess notation for White to move. If it was Black to move it would be 1. … ?
So this one is White to move and win. Black’s back rank is weak.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:
It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.
- Keep a firm grasp of Right and Wrong
- Stay involved with government on every level and don't let those bastards get away with a thing
- Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
- Keep talking to each other, whether here or elsewhere

Oh, and here's some kind of visitor flag counter thingy. Hey, all the cool blogs have one, so I should too. The Visitors Online thingy up at the top doesn't count anything, but it looks neat. It had better, since I paid actual money for it.
