Chess Eterna-ment Rankings

Inspection of the chess games on the blog found only one game (Tesseract vs. bookgirl_me) still in progress*. To keep things tidy going into the new year, the Chess GAPA (Robert) has adjudicated and closed all other games** of standard chess and calculated new MuseBlog Chess Ratings on the basis of the results. Ratings for Capablanca and Turbo Chess are unaffected.

Here are the new ratings, as of January 4, 2011 (numbers in parentheses indicate number of games on which the rating is based).

*(Finished on January 8; ratings updated to reflect the result.)

Latest update: 24 September 2011.

Attention, Chessplayers!

The latest version of our chess software has an option for bigger boards (with squares 48 pixels wide instead of the usual 32). We’re giving it a try. Let us know how you like it. If the boards are too big now, we can go back to the smaller ones.

(There’s a sample below the fold.)

Chess Problems, Set 3: Checkmate in Two Moves

The theme for this problem set is pins: situations in which a piece cannot move, because it screens a player’s king from check. (Under the rules of chess, you’re never allowed to make a move that puts your own king in check.)

In this simplified position, for example, Black’s rook, bishop, and pawn are all pinned:

[SetUp "1"]
[FEN "3R2rk/6p1/7b/6Q1/3B4/8/r3q4/6KR w - - 0 1"]
[Result "*"]
  

So White can play either

  • rook takes bishop, checkmate!
  • queen takes bishop, checkmate! or, most dramatically,
  • queen takes pawn, checkmate!

In each case, Black can’t recapture, because the pieces needed to do the job are pinned. So near, and yet so far! (Do you see why, after White plays queen takes pawn, neither Black’s rook nor bishop can capture the queen?)

Now, on to the real problems. Each is a “forced mate in two”: White moves, then Black moves, then White checkmates no matter what Black tries to do:

Chess Problems, Set 1

One of the big challenges for some chessplayers is knowing when they’ve won. Sometimes a checkmate is staring them in the face, but they don’t see it. These chess problems are designed to help you recognize checkmate.
