The Second Piatigorsky Cup, and Sourcing Spassky

[WARNING: This post is long and rambling. But now that I've written it I'm going to post it.]

In the post that will follow this one I feature a couple of quotes by Spassky that I came across online today. The problem with the quotes is that the online sources did not tell me the original source.

So I tried to remember which books Spassky had written, with some help from Amazon. I knew that Spassky hadn't written many books, mostly contributions to a few opening surveys. But I thought that he may have contributed to a book called How to Open a Chess Game, which had seven co-authors. I had to look this up on Amazon because I don't own a copy, to my regret. Spassky had not contributed to that book.

Move of the Day: June 17, 1974 edition

Way back when during the Nice, 1974 Olympiad, the Soviets faced the West German team on June 17th. On the first board, Anatoly Karpov, the then current wunderkind of the Soviet Chess Machine, faced off as White against long time West German Number 1 Wolfgang Unzicker. A typical slow Closed Ruy Lopez followed. Eventually, the following position was reached:

Karpov vs Unzicker

After 23...Qd8

I discovered this position in the 2015/6 issue of New In Chess. Parimarjan Negi wrote about it in his column Parimarjan's Chess Gym. I'll turn it over to him:

A well-known position. Black is ready to exchange rooks along the a-file, after which it will be much harder for White to generate anything on the queenside. Here Karpov played the amazing:

24. Ba7!

This absolutely paralyzes Black's queenside. The rest of the game is elementary technique, as White brought his other rook to the queenside, seemingly with the intention of penetrating via the a-file, but ending up completely suffocating Black, who was keeping himself ready for the bishop retreat that never happened.

An awkward seeming move, but a pretty idea! The rest of the game is a slow, steady squeeze. The whole game is in the viewer below.
