## The Chicago Open Chess tournament 2010

I’m sponsoring a friend (who I’ll identify through his American name, Justin, since I’m not sure how to spell his name right) in the Chicago Open chess tournament that started today in Chicago. Here is the tournament webpage for those interested in updates, and he’ll be emailing me with commentary later on this weekend.

## On opening theory

Check out the wikibooks on chess opening theory. Fascinating stuff. I prefer a variation on the Sicilian Defense and play it almost by rote in most informal games that I play, but there are some interesting games to study this summer.

## The job market for economists

From Chessbase:

Richárd’s parents are both economists. His father, Tamas, has built up a successful wood and parquetry business. A few years ago he moved from Szombathely to Sé, where his large young family could thrive better in the quiet village life. He has a strong amateur interest in history, a love that has passed on to Richárd. Richárd’s website, http://www.rapportrichard.hu, as designed by his father, opens with scenes from King Richard’s crusades.

Via MarginalRevolution, who excerpts some insightful portions on how chess theory is evolving in response to computer-trained players.

## Emanuel Lasker on Leonard Euler on Chess Valuation

The famed chessmaster Emanuel Lasker writes:

A table of simplest values in chess–that of the men themselves–was devised long ago. Leonard Euler, the mathematician, showed the way to  calculate these values mathematically by the principle that the average utility of a man is proportionate to its average mobility. This assumption is correct, because accordingto the rules of chess the effect of a man on a point is 0 when the man cannot move to the point, and is 1 for any man who can move to the point. This reasoning does not apply to the promotion of a Pawn. The Pawn therefore gains in value at the End Game stage. Apart from this factor, Leonard Euler’s method is sound, and the values he thus found agreed with those based on experience…

From Lasker’s “How to Play Chess”.

That’s the Euler, of course. The Leonard Euler who is responsible for so much of mathematics, including the prime number theorem. I had no clue that he also developed the simple valuation system for chess as well.
