(Not) Winning a Won Game

Here's another game from last month's ICA Girls' Invitational Championship at the North Shore Chess Center.  I hope that both Adele and Miranda will forgive me for publishing a game in which they made 51 good moves and only one bad one.  But I found this game so instructive because it's so typical.

The stylish way to win a game is by direct attack against the enemy king.  In real life, we don't get to be stylish as often as we'd like.  So we win a piece instead.  When we talk about "winning a piece" in chess, we mean winning a bishop or a knight, worth about three pawns.  In this game,  Miranda wins a piece for a pawn: in quiet middlegame positions, this advantage is usually sufficient for a win.

When you win a piece for a pawn, what's the easiest way to win?  Well, you'd like to use your extra material to queen a pawn and then checkmate with overwhelming force.

But put yourself in your worthy opponent's shoes.  You may be winning, but you have one less pawn than she does.  So if the defender could keep trading one of her pawns for one of your pawns until there was only one pawn left, that extra pawn would be hers.  True, you would still be up a piece, but you'd have to look for a way to checkmate without making a queen.  That's much harder!  (Rule of thumb: in pawnless endings, one often has to be up by five "points" to win.) 

DEFENDERS WANT TO TRADE PAWNS, NOT PIECES.  (Here, we use "pieces" in a second sense: kings, queens, rooks, bishops, and knights, but not pawns.  Yes, I know we can't trade kings.  And yes, we usually talk about chess sets having thirty-two pieces, not sixteen pieces and sixteen pawns: this third meaning of "piece" is actually the most common one.)

THE SUPERIOR SIDE WANTS TO TRADE PIECES, NOT PAWNS.  Every pawn is a potential queen.  Guard your potential queens just as you do the one that's already on the board!

White to play
Miranda chooses a Meran Variation setup. As White's bishop is not that active on d2, Black should get nice play.

Congratulations to Penny Xu and Adele Padgett

Penny (who was only 12 years old as of February 2010) and Adele (15 years old as of 2/2010) tied for first in the Illinois Chess Association's Girls Invitational Championship this weekend. Each scored 3 wins, 1 loss, and 1 draw. Penny takes the title on tiebreaks.

In the following game, Penny and and her opponent Shayna Provine both display a very mature handling of the Sicilian.  (Chicagoans of a certain age know all about the dangers of the anti-Najdorf system 6.g3, as we all suffered at the hands of Leo Kaushansky.)  As I played through the game score on my iPhone, I found myself wondering who Penny's coach could be.

Then I saw Penny give Tamara Golovey a hug in the hotel lobby.  Aha!

P.S.  What cool shot did Penny miss on White's 24th move?  (I didn't notice it at first: she had to show it to me.)
