Humans will never learn to "think like computers;" it's simply impossible.  That doesn't mean that we can't learn something from a computer's games, however.

How do you feel that reading the book changed your opening repertoire ¿

I got the impression that AZ does not play 1.e4 because of 1...e5 - specifically the Berlin, which AZ favors as Black.  I have wondered whether AZ would adopt 1.e4 if the opponent had to play anything other than 1...e5.


The current best nets for Lc0 (T30 and T40) both favor 1. e4, and both are stronger than A0. Refer to the second graphs on these pages:

Sacrificing pawns more freely now, playing more on the wings by using a and h pawns more, changed opening repertoire from 1.d4 to 1. c4 and 1. Nf3 and stopped playing for advantages as White through known theory and now focusing on creating better outpost squares for pieces.  More actively thinking now: "what would AZ do here" and ," how can I give up material to gain positional advantage."


Thank you!

I am a (bad) amateur who plays exclusively 1. e4, so the following question comes from a place of total ignorance. What is so special about 1. c4 and Nf3 as compared to d4? My impression is that many of the lines of the former two options transpose to d4 lines anyway, so that they are tightly related.

Do you think the c4/Nf3 are somehow objectively better (and if so, for what reason? lc0, which a stronger neural network-based engine than A0, does not seem to favor c4/Nf3). Or are you making a practical decision, trying to enter positions you might be more familiar with than your opponent, and which may give them more opportunities to go wrong (because typically people are less booked up and experienced against these less common openings, for instance)? Or some other reason?


People play 1.Nf3 and 1.c4 for different reasons. Many want to play main 1.d4 lines against most defenses, but, say, avoid certain sharp defenses, playing (after 1.Nf3) an Anti-Benoni rather than a Benoni, or (after 1.c4) an Anti-Gruenfeld rather than a Gruenfeld. Of course, they have to be ready for 1..c5, in which case they cannot reach a 1.d4 mainline if their opponents do not want them to--and, in the case of 1.c4, also 1...e5 with some of the English main lines.

Other players  have no intention of playing any main 1.d4 lines, and want to go into a Reti, KIA, English, etc.

Still others are winging it and just want to create fluid, unfamiliar (mostly hypermodern) situations for their opponents, as you suggested.

1.d4 2.Nf3 is a similar beast--some play it for d-pawn specials, others to play 3.c4 while avoiding certain sharp lines.

--All these lines are definitely no stronger than 1.d4 2.c4 in any objective sense--on the contrary. While that classic opening permits Black some sharp defenses (QGA, Benko, Albin, Schara), it also gives White some of his most theoretically powerful lines (the flick-knife Benoni, Saemisch KID, QGD Exchange with Ne2 and f3, etc), where pressure on Black is maintained for a long time even if eventually Black can thread through to equality.

I got the book on the FwdChess app.  It looks interesting.  The authors try to compare AZ's strategies with maneuvers by great human players in classic/historical games.  This adds to the pedagogic value and softens the criticism that readers should not try to play like a computer.

I got the impression that AZ does not play 1.e4 because of 1...e5 - specifically the Berlin, which AZ favors as Black.  I have wondered whether AZ would adopt 1.e4 if the opponent had to play anything other than 1...e5.

Sadler & Regan also recommended this flexible 1.Nf3 or 1.c4 or 1.d4 approach in "Chess for Life", citing Pia Cramling as a model player.  The general approach is to be shifty/crafty/flexible as White by employing move orders and transpositions.  And as Black, to study a mainline in extreme depth.  Sadler & Regan write: "It is easier to destroy [as Black] than create [as White]."

In a Youtube video, Natasha Regan stated that after working on the book she tried playing "like AZ" with poor results.  She commented that her victorious opponents, in the post-mortems, patronizingly tried to teach her that it is better to play in the center than to throw the rook-pawns.

I have already significantly changed my own playing style including opening repertoire and middle game planning with highly successful results, all based on studying AZ games.  I just put my rating at its all time peak, which is something most people close to 60 years old do not find so easy to do, and I attribute much of it to the change in my play that I decided to make after spending months studying these games.

AZ is an absolute game changer (for those of us willing to change our game).


Could you comment on what you've learned and changed, if you have the time? I'd be extremely interested in what you have to say, and I'm sure others would too.



A over simplified take:


Sacrificing pawns more freely now, playing more on the wings by using a and h pawns more, changed opening repertoire from 1.d4 to 1. c4 and 1. Nf3 and stopped playing for advantages as White through known theory and now focusing on creating better outpost squares for pieces.  More actively thinking now: "what would AZ do here" and ," how can I give up material to gain positional advantage."

It used to be something of a Larsen speciality to prod the rook pawns down the board. But like Alpha Zero, he was self-taught, mostly at least.


I recall he said that he wanted to call his selected games collection _The Strategic Significance of the Rook Pawns_ but the publisher wouldn't let him.

Plus, he wrote Zero Hour for Operative Opening Models! More than coincidence? I think not! Wink

I wonder if soon human players can train with such strong computerprogrammes and learn how to "think" like computers and then play like computers.


It would be amusing to see GMs next having trained so much to think like computers, that their moves are the first lines of engine analyses  Cheesy

Yes, I'm reading it at the moment – very, very interesting – though I can't say yet whether it will change my play at all. Well, perhaps I'll push my h-pawn down the board even more than I usually do Smiley
