A Climactic Combination

I finally made the time to watch "The Luzhin Defence" last week, and I must say it was well worth it. Visually it is a magnificent movie (with a lot of the scenery reminding me of Bled, although it was shot around Lake Como) and the performances of all the actors were very good. Even the chess scenes were pretty well done (GM Jon Speelman was a consultant for the movie) although like most movies about chess, there were some shortcuts taken for dramatic effect.
One of the most interesting scenes involved a brilliant combination involving a rook and queen sac. It looked familiar while watching it, and I recalled it somehow involving Max Euwe. It turns out that Euwe was on the losing end of the combination, with the winner being Milan Vidmar Sr. It also turns out the position used in the movie was (a) not exactly the same as in the game and (b) this resulted in the actual combination being illegal.
Here is the game, with the diagram at the crucial point. The problem for the movie was that the Black rook on c2 was placed on c1, thereby pinning the rook on the d file, meaning the final move couldn't legally be played!
(And yes for those who have already seen the movie, I did notice there was other action going on between the moves, hence the title of the post)

A forced win in Blitz

There are certain openings that work better at Blitz than they do at longer time controls. Normally these are trappy lines involving material investment, although sometimes they are so dodgy that the opponent chews up time looking for the immediate refutation.
With the increased popularity of online "bullet' chess (1 0), you now see the Halloween Gambit (1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Nxe5) or the Hiroshima Variation of the Sicilian (1.e4 c5 2.Qh5) becoming more well known. But there are also the 'classics' that you may need to know.
I watched the post-mortem of a game yesterday involving a very early sac on f2. While I didn't see the game myself, I did see various positions that may have arisen. In the end the conclusion from both players was that it was winning for Black, but mainly due to the fast time control.
While I don't have the game played yesterday, I have another game in the same line, but with the following kicker. Rather than being a forced win, it turns out that it may well be a forced draw, and a draw that has been around for over 100 years.

Miniature of the Month - June 2009

The Miniature of the Month for June 2009 could almost be titled 'Caught in the Crosshairs'. After Blacks 13th move the White Queen has nowhere to run, and White has to surrender the exchange to protect the lady.

The Six Hats of Chess Thinking

"Six Thinking Hats" by Edward De Bono is considered as one of the most innovative books on thinking and the decision making process. I've often wondered whether the various 'hats', and the thinking process, could be applied to chess. I'm not sure it is the most efficient way to choose a move during the game, but here is my attempt at matching hats to chess concepts.
For those unfamiliar with 'Six Thinking Hats', each hat stands for a different part of the thought process. And while making a decision (or coming to a conclusion), each hat is worn as a way of applying the different thinking techniques. Here is a list of hats (by colour), and the related chess concepts.
Blue Hat - Controlling the thinking process. In chess this firstly concerns how much thinking you need to do. You may only have one reply (eg a recapture) or you may be short of time. At the end of the thinking process you also use this to decide on your move (or to decide you've done enough thinking).
White Hat - Facts and Figures. In chess this would be material balance, plus position factors (open files, outposts, doubles pawns etc). Knowing what problem you are solving often puts you half way to the answer.
Red Hat - Emotions and Feelings. I would see this as 'How do I feel about my position?'. Also recognising whether you are nervous or over-confidant might help you in your approach to the rest of the game. And of course 'Am I playing for a win or am I playing for a draw?'
Black Hat - Caution and Care. In chess this would be looking for immediate threats from your opponent, and at a higher level, prophylactic thinking. 'What is my opponent threatening to do?' would be a good question to ask while wearing this hat.
Green Hat - Creative thinking. Probably best used when obvious moves don't seem to help. The 'Where do I want my pieces to be?' question falls under this category.
Yellow Hat - Constructive thinking. Ultimately you need to analyse your alternatives, and here is where you do it. This is the 'I move, then they move, then I move' part of the process.

Now while this may seem to be an impractical way of choosing a move (as I feel that chess thinking involves a lot of overlapping concepts) there is some good news. This approach to choosing your move has already been described, in a sense, and certainly predates the publication of De Bono's book. I am referring to CJS Purdy's 'System for choosing a move' which he laid out in the pages of "Chess World", and which he himself used to win the first World Correspondence Championship.
So it is possible to bring a formal thinking process into your game, but whether it is practical is a question I have yet to answer.

Changing the move order

I recently read a suggestion (possibly from Hans Ree), that if a combination doesn't seem to work, try changing the move order. Playing a less obvious move may bring greater rewards than charging headlong into the gates.
I recently gave a game from the 1953 Zurich Candidates tournament where Paul Keres came unstuck after trying a novelty in the opening. To balance the ledger I have a game from the same event, where Keres benefited from an unsuccessful innovation from Isaac Boleslavsky. It also illustrates the point of this article, in that Boleslavsky only looked at Keres' possible replies in one order, and didn't consider the alternative.

Chess in Fiction

Via the wonderful XKCD I visited TVTropes, which is a catalogue of tricks used in writing fiction. As with most sites of this nature, a simple test of usefulness is to type 'chess' into the search function on the page.
Well TVTropes has a number of categories to with chess. The most interesting I found were
But be warned TVTropes will ruin your life

SA Open Results

I've finally managed to get the final results from the South African Open (the website, while technically clever, doesn't provide much information).
IM Amon Simutowe (Zambia) was the outright winner with 9.5/11. In second place was GM Gawain Jones (England, but playing from Melbourne, Australia) on 9.0/11. IM Puchen Wang (New Zealand) finished in a tie for third on 8.5, and he was also playing from Melbourne. The other 'remote' player, IM Mirko Rujevic (Australia) finished on 7.5, but he did it particularly tough, working during the day and then playing his games in the middle of the night (due to the difference in time zones between Melbourne and South Africa).
