AlphaZero's Thoughts
by GM Matthew Sadler and WIM Natasha Regan
The idea of analysing the World Championship Match between Magnus Carlsen and Fabiano Caruana together with AlphaZero, London-based DeepMind’s general-purpose artificial intelligence system, first occurred to us just after the thrilling Candidates Tournament held in Berlin in March 2018. Still in the middle of writing our book about AlphaZero and thrilled by the incredible games we were seeing, we felt that — despite all the attention that the match would receive from other silicon and human commentators — AlphaZero’s perspective could still add something unique and valuable.
Part of the mystery of a match lies in the opening choices, in which the intentions of a competitor never fully become revealed. For example, Caruana’s Queen’s Gambit Declined seemed to cast a huge shadow over Carlsen’s White games. From the outside, it felt as if Caruana’s choice of opening had significantly disrupted Carlsen’s strategy with the White pieces and made him lose confidence in 1.d4. The strange thing is that we never got to see the reason for this loss of confidence: both in Game 2 and Game 7, Carlsen attempted to make progress in sidelines rather than testing out Caruana’s preparation in the main lines.
In this article, we thought it would be interesting to take a deeper look at some of those intriguing moments in the Queen’s Gambit Declined and get AlphaZero’s thoughts on what it considered to be best play.
Game 2 was in retrospect a crucial moment for Caruana in the match: after a fraught first game in which he had been required to muster all his defensive mastery to counter Carlsen’s stellar opening and middlegame strategy, Caruana achieved the first of many comfortable draws with Black with excellent preparation.
As you can see, analysing with AlphaZero is a rollercoaster ride. While its play is generally sound and strategical, it is extremely sensitive to the slightest opportunities for active counterplay, which it prosecutes with great energy and purpose. This gives great feedback when trying out ideas against it, especially those involving the arrangement of your pieces on different sets of squares: AlphaZero won’t be shy to shout a low evaluation at you if it doesn’t like your choices. All-in-all, it’s been a great experience analysing with an engine quite unlike any other, and we hope you enjoyed this insight into the brain of an artificial intelligence system that taught itself to play chess.
How AlphaZero evaluates
AlphaZero’s evaluation is based on how it would expect to do against itself from the current position. It uses a weighted average of all the lines it has seen during its analysis which lets AlphaZero take account of everything going on in the position before giving its final evaluation. We think this is what gives AlphaZero its intuitive feel for positions, allowing it to steer towards positions that are generally promising. In this article we talk about the evaluation as a percentage. An expected score of 70% for White would signify good winning chances and a definite advantage for White.
Sadler on Books
Simon Williams has been busy recently with two DVD’s for ChessBase: one on the Exchange Slav: Simple but Powerful: Ex-change on d5 in the Slav and the Queen’s Gambit, and one on the Queen’s Gambit Declined 5.♗f4: A Dynamic Weapon against the Queen’s Gambit Declined — 5.♗f4.
Williams is not always the most concise of presenters, but he is unfailingly enthusiastic and strongly focused on giving the viewer the minimum number of lines to be able to play an opening properly rather than providing reams of long variations. As you might expect, this approach works better for some openings than for others. I felt that the analysis in the DVD on the QGD was erring on the light side, particularly in intricate variations such as the old mainline (1.d4 d5 2.c4 e6 3.♘c3 ♘f6 4.♘f3 ♗e7 5.♗f4 0-0 6.e3 c5 7.dxc5 ♗xc5 8.♕c2 ♘c6 9.a3 ♕a5 10.0-0-0). I felt that I had been entertained, but possibly learnt too little!
On this DVD, we will look at a simple-to-learn yet surprisingly effective system that White can play after 1 d4 d5. In all cases White will play 2 c4 - and if given the chance, 3 cxd5!
The other DVD works much better and Williams does his usual nice approach of offering a choice of lines — the normal solid main lines as well as something spicy. This time, the idea that caught my eye was: 1.d4 d5 2.c4 c6 3.cxd5 cxd5 4.♘c3 ♘f6 5.f3
The Berliner Exchange Slav. I first saw this line mentioned in former Correspondence World Champion and computer programmer Hans Berliner’s The System, with the main line given as: 5...♘c6 6.e4 dxe4 7.d5 ♘e5 8.fxe4 e6
Unfortunately, Berliner was very cagey about this line: ‘Despite the fact that there are numerous violent attacking attempts here, and I have spent hundreds of hours on this, including much computer help, I have not been able to find any concrete advantage for White.’
It just shows you how times change! When Berliner’s book came out in 1999, I scoffed a little at all these ridiculous opening ideas. Fifteen years’ work with engines later, nothing seems stupid anymore!
In any case, Simon Williams does a pretty good job in this DVD of making me enthusiastic for the Exchange Slav, which is not something I’d ever think I’d say! 3 stars for the QGD and 4 stars for the Exchange Slav.
This DVD concentrates on the increasingly popular 5.Bf4 variation of the Queen's Gambit Declined and gives White a dynamic and aggressive weapon against Black's set-up.
