Critical moments, or, Why do smart players make foolish choices? (Part I)

The words "criticism" and "crisis" share an etymology.  Sometimes we recognize a critical moment in our games.  Having watched reruns of House, we may be able to make a differential diagnosis.  Being human, our reasonable guess may not be right, as we discover in the post-mortem.

I haven't really begun to analyze my games from this weekend's Tim Just's Winter Open XXV, but I think this may be an example:

Charles Swan-Bill Brock
After 16.Qxf3: Black to move

I have to choose how to give my extra piece back.  I played 16...Bxh3, but I now suspect (despite my engine's initial enthusiasm) that it's a mistake to cede the f5 square to the White Nf1.  My guess (which may well be wrong!) is that 16...Qe7 17.dxe6 fxe6, covering my light square weaknesses and creating a second semi-open file for my rooks, would've been stronger.  But either choice is reasonable: even Dr. House's initial diagnosis is usually wrong.

But sometimes the crisis is self-inflicted.  I found it humbling to try to explain my mental lapse a few moves later (my second senseless blunder of the week!)

Charles Swan-Bill Brock
After 18.Kh2: Black to move

I analyzed the piece sacrifice 18...O-O-O 19.Qxf6 Bxf2, hitting both the hanging Re1 and the g1 square.  If one peers deep into the position ;-) , one might notice a refutation.  (I did manage to generate some cheapo potential in the game continuation, but Swan put me away very calmly and efficiently.  His other games, including his loss to Aliyev, were even more impressive.)  

It was a consolation that other strong players could make equally strange oversights.

Bill Brock-Christopher Girardo
After 17.c5: Black to move

Black's choice, 17...Rc8, certainly looks natural.  However....

Dmitry Sergatskov-Bill Brock
White to move after 14...f7-f5

Dmitry's 15.e4 seeks to take advantage of the loose knight on d7.  However....

New K-8 Invitational Announced

Andi Rosen reports on her hard work at the Illinois Chess Association website.

In the course of skimming Andi's report (I do actually work for a living), I noticed an embarrassing omission from my Tim Just's Winter Open XXV report below.  The winner of the Booster Section, David Peng, was only 7 years old in December 2010!

Eric Rosen wins Tim Just's Winter Open XXV(?)

The consensus this weekend is that this was not the 25th annual TJWO.  Wayne Clark thought it was the 27th; Chief TD Daniel Parmet said that it had been run as early as 1983, which (assuming no skips) would make it the 29th.  I remember when it was held at Illinois Beach State Park: great location if you don't get a blizzard!

Eric Rosen won comfortably with 4½-½.  Timur Aliyev, Under 2000 winner Charles Swan of Whitney Young, and Under 2200 winner Bill Brock tied for second with 4-1 each.  Swan picked up 120 rating points in one weekend: not bad!  Congratulations to Fredric Cohen for making Class A!

David Peng won the booster with 4½-½.  Roger Wang, Saagar Gupta, Avinash Rajendra, and Ryan Toepfer (who went from 1481 to 1647!) tied for second with 4-1.

Thanks to Tim Just, Wayne Clark, and Daniel Parmet for another very nice event.  The clocks provided by the North American Chess Association allowed the event to use the thirty-second increment setting.  Even with only 90 minutes each for the game, one can approximate Real Chess.  Very pleasant for us old folks!

Hedgehogs win; blogger loses

This Board 1 matchup was crucial to the Hedgehogs' 4-2 victory over the AMA Rogue Squadron in Chicago Industrial Chess League play last night.  Both of us had read (and forgotten) the relevant chapter of Mihail Marin's Beating the Open Games....

Very nice preparation and play by Michael Rauchman!

A simple little ending

White to play
Zhu Chen-Zhao Xue, Ulanbaatar 2010

There are only four pieces on the board, but the "simple" position is still complicated enough for former Women's World Champion Zhu Chen to make a fatal blunder.  Notes based on Dejan Bojkov's comments in New in Chess 2010.7

How many of us would have made the same blunder as Zhu Chen?

A trap in the King's Indian

In the King's Indian Defense, after 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2, usual is 6...e5 7.0-0, and now Black's most popular moves are 7...Nc6, 7...Nbd7, and even 7...Na6. Sometimes Black futzes around and first plays 6...Nbd7 7.0-0, and now a waiting move like 7...Re8?! or 7...c6?!, thinking that Black need not rush to play ...e5. This is a bad idea, since 8.e5! followed by the pawn sacrifice e6! wrecks Black's pawn structure. In the game below, Black made things worse (as he/she usually does) with 8...dex5 9.dxe5 Ng4 (better is 9...Ne8!, allowing the pawn sac 10.e6! fxe6 11.Ng5) 10.e6! fxe6? (10...Nde5! is better) 11.Ng5! (diagram). I have reached this (or a similar position with Black's pawn back on c6 and ...Re8 having been played) dozens of times in Internet games. Black is already lost in light of White's threats of 12.Bxg4 (winning a piece) and 12.Nxe6 (winning the exchange). Like most of my opponents, Black responded with the "traditional" 11...Nde5?, losing a piece, and lost quickly.

It's not *billed* as a Hannukah tournament...

On Sunday, December 5th, Chess Scholars is holding a K-8 tournament at the Solomon Schechter Day School in Skokie.

"A big feast of chess over Turkey Day weekend"


 A report on the amateur closed round robins at the North Shore Chess Center from TheChessDad.com

a cool and free iPhone app

Any chess player (absolute beginner to master) with an iPhone, iPad, or iPod Touch should enjoy Chess Problems, a free application by PsyGames.

The interface is simple and intuitive.  One can choose from directmates (e.g., "mate in two moves"),  helpmates, and selfmates, sorted by level of difficulty (pawn to queen)


I knew the answer to the following one right away because my grandmother owned a mid-nineteenth century edition of Hoyle.  The chess section gave this problem (or one like it!), accompanied by a version of the legend of Princess Dilaram.


Bonus Socius manuscript, circa 1266 (!)
White to play and mate in two moves

Helpmates are fun!  In a helpmate in two moves, Black moves first, and the two sides work together to allow White to checkmate Black on White's second move.

Lind 1941
Helpmate in two moves
(remember that Black moves first in a helpmate!)

Selfmates are fun, too!

 Widlet, 1982
Selfmate in two moves
(White to play and force Black to checkmate White on Black's second move: unlike the helpmate, the two sides are not cooperating)

Some of the positions are easy enough for absolute beginners to solve.  But the simple king and queen vs. king position below took me 1:18 to solve.  I guarantee that anyone who knows the rules of chess and has a little patience should be able to solve it.  Some of you will see the solution at sight, others might need five minute to explore all the possibilities.

Courtenay, 1868
White to play and mate in two moves

And I sat staring for almost 17  minutes at this famous Mansfield two-mover even though I knew I'd seen it before.  As soon as one sees the key move, one slaps one's head and says, "Of course!"  But the trick is to find the key move...

I think that chess problems are of more than marginal benefit to practical players: they force us to understand the powers of the pieces, they push us to think outside the box, and they train us in brute-force calculation in bizarre positions.

Mansfield 1933
White to play and mate in two moves

I have one trivial complaint about this app.  When you find the key move, only one defense is offered, no matter how many times you play through the solution.  (Part of the beauty of these problems is that various defenses to the key move lead to various mates.)  But that's a quibble.

Strongly recommended!

Kasparov and Short in St. Lou after Thanksgiving Tourney

SAINT LOUIS, November 23, 2010 – Grandmaster Garry Kasparov, widely recognized as the world’s greatest chess player, has announced he will be making an appearance at the Chess Club and Scholastic Center of Saint Louis on Monday, November 29, just one day after the conclusion of the Thanksgiving Open tourney featuring renowned GM Nigel Short and an $11,000 prize fund.

The simul, scheduled to follow the lecture at 7:30 p.m., has been capped at 30 participants, but those interested can still submit their name for the wait list.

This is a once-in-a-lifetime opportunity to meet two of the best players in the world, who once battled one another for the World Chess Championship title in 1993.

    * WGM Sabina Foisor
    * WIM Alisa Melekhina

Registration costs $119 for the three-day option and $118 for the two-day option. There will be a re-entry option available for $60.

This event will be a FIDE-rated, six-round, G/120 event in three sections: Open, U1800 and U1400. The prize breakdown is as follows:

Dr. Nunn's guide for the perplexed

From chapter 8 of Nunn's Chess Endings, Volume 2 (I haven't gotten around to buying Volume 1):

8.2 Rook vs Pawns

There are a surprising number of subtleties in endings in which a lone rook faces enemy pawns, and here we shall focus on those which are of greatest importance in over-the-board play.

8.2.1 Hesitation checks

By hesitation check I mean that a piece traveling from square A to square B gives an intermediary check on square C before moving to B.  The point is that if the enemy king is already on its best square, the hesitation check forces the king to an inferior square.  It might seem unnecessary to give a special name to such an elementary concept, but it often helps to have a label to refer to a particular theme.  Hesitation checks play an important role in rook endings and are often overlooked in practice.
 Have another go at it!

Rook endings (or, the love that dare not speak its name)

If you enjoy rook endings as much as I do, you'll love Nunn's Chess Endings, Volume 2.  John Nunn's books are always full of top-rate material, but unfortunately, much of it has often whizzed over my head.  (For example: Secrets of Rook Endings.)  But Nunn has put a lot of work into organizing his mind-bending examples thematically and giving the reader guidance.  The examples are still difficult, but Nunn has never been this reader-friendly before!

For example, here are the first three diagrams in Nunn's book:


Fries Nielsen-Plachetka, Rimavska Sobota 1991
White to play and win
Usually when I get such a position, I have three minutes left on the clock and am reduced to counting on my fingers: "I go here, he goes there, I go here..."



Analysis diagram
White to play and draw

Hey! Didn't I learn in one of my beginners' books that two pawns on the sixth rank always win against an unassisted rook?  And indeed, 1.Rxh3? does lose.  Why?  And where's the darn draw?



Penrose-Perkins, British Championship, 1972
White to play and draw
I found the first position hard and the third position mind-numbingly difficult.  Back with Nunn's guidance in a little bit.

GreenCastleBlock on rook endings

I always learn a lot from Matt Pullin's videos on endgames. He relies on his brain, not a computer engine or database, and he's a very good explainer.



But it just so happens that James Fagan and I had this very ending in 1997. I think Matt misses a win for Black at one moment in his video.


You really should be subscribing to Matt's YouTube channel, GreenCastleBlock!

Kavalek remembers Evans

Mark Taimanov-Larry Evans
USSR-USA match, New York 1955
Black to play

Taimanov has just sacrificed material with 19.Rxc7.  If Black plays the natural 19...Qxc7, White plays the powerful 20.d6.  What to do?

Kavalek annotates this beautiful win by Evans.

Is this calcuation or pattern recognition?

This one is for Maret Thorpe, who thinks I've gone off my rocker!



Felix Zemdegs set a Rubik's Cube solving record in Melbourne this weekend. Trust me, you have time to watch.  (If you give one to me, I should be able to solve it in five minutes or so: there was a time when I was much faster....)

The more interesting question: how does Felix (who is the best of many lightning-fast expert solvers) do what he does?  I'd suggest that the answer might be of interest to chess players, and others.....

All Grade results (6th, 7th, and 8th grades)

There was a three-way tie for first in the 42-player 6th-grade section: Alec Feygin, Akash Mattu, and Colton Longstreth, all with 4-0 scores.  Steven Do, Brayden Estes, Riley Brands, Nate Tracy-Amoroso, Matt Szarkowicz, Abraham Cornejo, Barry Brookins, and Harrison Burns tied for fourth with 3-1.

Joey Bikus and Allen Guo tied for first in the 47-player 7th-grade section.  Phillip Parker-Turner, Jason Kitson, Samuel Heil, Ryan Toepfer, Justin Wang, Jonathan Hrach, Niresh Kuganeswaran, Narayan Karthik Karra, Elliana Faletsky, Alexander Pilia, Mark Jungo, and Michael May all scored 3-1 to tie for third.

Maximilian Zinski and Chase Walbert went 4-0 to tie for first in the 8th-grade section, which drew 48 players.  Nathaniel Kranjc and David Dlott drew each other in the final round to finish with an undefeated 3½-½.

More photos:





Chess can be a cruel game

You can play like a genius for 84 moves, and throw it all away in time pressure:

Grischuk-Nakamura, Tal Memorial 2010
(finished just a few minutes ago)
Black to play and win

There are two reasonable ways to threaten mate on g3: 84....Qe1 and 84...Qf3.  Both moves have problems: after 84...Qe1, White can try to set up a stalemate defense by allowing ...Qxg3 and running the king to h1.  After 84...Qf3, 85.Nxe5+ seems to force a draw: or does it?

Which move would you choose?

Grischuk-Nakamura continues

Both players are close to playing on the 30-second increment alone.  Nakamura is probably winning, but Grischuk has serious drawing chances.

Jonathan Speelman is commenting live on ICC.

All Grade results (4th & 5th grades)

First, a few more pictures:






Miranda Liu won the 67-player 4th-grade section with a perfect 5-0.  Chetan Reddy and Jonathan Tan drew with each other and won the rest of their games to take equal second with 4½.  Matthew Stevens, Jack Xiao, Nikhil Kalghatgi, Cassie Parent, Adarsh Mattu, Ricky Roman, Brian Chung, and Andrew Lim tied for fourth with 4-1 scores.

Anshul Adve and Jack Curcio tied for first in the 58-player 5th-grade section with a draw against each other and wins in their other four games.  James Wei, Abe Sun, Haoyang Yu, Shayna Provine, Lorenzo Barbin, Andrew Fei, Daniel Bronfein, and Mihir Bafna tied for third with 4-1 scores.

Amazing...

Nakamura (playing right now!) is on the cusp of tying for first in the Tal Memorial.  (Mamedyarov lost to Gelfand...)

Great live video stream here.

All Grade results (Kindergarten, 1st, 2nd, & 3rd)

Unofficial nose count was 505 players!

Kindergarten: Nikolai Rhodes scored a perfect 5-0; Huaye Jeffrey Lin took second with 4-1.
