Explorations in Man-Assisted
Machine Chess (MAMS)

Blessed to live in the era of the continuing microelectronic revolution as a member of the first generation in the history of mankind that has not suffered from famine-war-disease-poverty-catastrophe-dictatorship, etc., at the age of 60+ I have the privilege, on top of all the aforementioned, to fulfill a youthful passion: enjoy classic chess on a grandmaster level in the Man-Assisted-Machine mode.

The machine calculates, it remembers all opening variations and plays automated endgames with an iron fist.  "All" we have to do is devise visionary intuitive human non-computer moves in an otherwise error-free sequence.  We navigate, fly, design, gather information, perform arithmetic operations machine-assisted, so why not play chess that way?

Departing from Fischer's unofficial paradigm that the noble game is a draw when played without calculative errors, I attacked chess programs for 5-7 years on the basis of the idea that the human player HAS to find a non-computer risk move or preferably two or more of them to unbalance a position, via material sacrifice in the form of gambits, piece-for-pawns exchange or rook-for-bishop, etc.

This led to resurrection of the 19th century dazzling Morphyan combinatory style in open e4/e5 games.  The Godfather of all Dutch chessplayers, the eminent Dr. Max Euwe, a math teacher and one of the first IT-pioneers,  initiated innocent youth to the precious Morphy-Andersen gems of chess in his marvelous booklet: "Uncle John teaches his young nephew how to play chess."

Love at first sight.

Entire generations were lost to chess from then on.  Alekhine called The Netherlands a "chess-crazed" country.  Euwe continued to teach the more methodological cautious style in the classic book "Judgment and Planning In Chess".  Things were getting serious.  The subtle strategies of Capablanca, Botvinnik, Karpov and at present: Anand.

The gentleman diplomacy of the later Prof. Dr. Euwe - chess teaches one to have good manners, dress well and move the pieces ever so tender with butterfly hands and all this affects one's walk-of-life in general - brought him to the position of president of FIDE, during which we enjoyed, via primitive on-line telecommunication, the legendary Fischer-Spassky match in Reykjavik 1972.  Euwe complied with Fischer's proposal and persuaded the Soviets to substitute the Candidate Tournament for Man-to-Man play off matches in the ascension to the world title.

The rest is history.

I have an inborn, rebellious, obstinate, suspicious, but nonetheless good-humored temperament inclined to engage in a high-risk on-edge lifestyle.  Reentering the Halls of Caissa in the computer era after having been absent for 40 years, naturally I ignored the lessons of our former chess teacher, No football for the coach!  The dogma of the enduring moderate advantage?  No such thing!  Unmitigated Audacity!  Provoke!  Defy defy defy!  We are NOT going to go Dutch here.  Sacrifice!  Be bigger then Life.  Live now!  Pay later!  Don't die before you are dead!

Here comes the Evel Knievel of chess!

Until I saw THIS game:

**************

Geller-Smyslov Moscow 1956

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7 7.Bc4 c5 8.Ne2 0–0 9.0–0 Nc6 10.Be3 Qc7 11.Rc1 Rd8 12.f4 e6 13.Kh1 b6 14.f5 Na5 15.Bd3 exf5 16.exf5 Bb7 17.Qd2 Re8 18.Ng3 Qc6 19.Rf2 Rad8 20.Bh6 Bh8 21.Qf4 Rd7 22.Ne4 c4 23.Bc2








23...Rde7(?)  (But White is very good after just about any Black move.) 24.Rcf1 Rxe4 (desperation) 25.fxg6 f6 26.Qg5(?) [Qg3 wins right away] Qd7 27.Kg1 Bg7 28.Rxf6 Rg4 29.gxh7+ Kh8 30.Bxg7+ Qxg7 31.Qxg4

and a crushing White win.

Geller does not make any spectacular risk move(s) nor does he bring material sacrifice to the table.  When you replay the game on a computer, you will note that step-by-step with every move numerically the White advantage grows and grows and grows.  Frightening.  I guess after 21.Qf4 the game is lost for Black in all lines, but then again: where did Smyslov make a bad move in the first 20?  All of Geller's moves are readily found by a machine.

There goes your no-risk no-win no-guts no-glory dogma, Mr. Alberts!  Can we develop this Gellerian ever-increasing advantage style in computer chess?

Yes we can.

AA-Fritz-10
(unlimited time, full analysis mode, main lines after 20 games
to let the program construe its best defense)

Open Sicilian Paulsen-Kan-Taimanov [C52] with 5.c4

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.c4 Nf6 6.Nc3 Qc7 7.Be2 d6 8.0–0 Be7 9.Be3 0–0 10.f4








The stem diagram.  Naturally this position can be reached from 2...d6 and 7...e6 leaving the e6/Bb4-lines for what they are at the moment.  Euwe's successor, Jan Hein Donner, taught us that Black steers toward d5 in the e6-system.  To fence off both d5 and b5 White plays 5.c4 in the 4...a6 Kan variation.  In eventual ...e5-lines for Black, the pawn-d6 becomes a chronic weakness.

It all seems rather innocent BUT: ten moves on the board and Black is LOST!  White can safely advance g4 and if need be b4, a4 and h4 as well.  The white pieces operate in perfect Capablanca-like harmony and the black ones do NOT.

Look and shiver:

10...b6 11.Rc1 Nbd7 12.g4 Bb7 13.Bf3 Nc5 14.Qc2 h6 15.b4 Ncd7 16.Qe2 Nh7 17.f5 e5 18.f6 Bxf6 19.Nf5 Bg5 20.h4 Bxe3+ 21.Qxe3 g6 22.Nxh6+ Kg7 23.Rfd1 Rh8 24.h5 Nhf8 25.g5 Ne6 26.Bg4 Nf4 27.Ne2 Nxe2+ 28.Qxe2 Nf8 [ 28.- Rhf8 or Raf8 no good either, White has a win here already] 29.Rf1 Rxh6 30.gxh6+ Kxh6 31.Rf2 f5 32.exf5 g5 33.f6 Qc6 34.Kh2 a5 35.b5 Qe4 36.Qxe4 Bxe4 37.f7 Rd8 38.Rd1 Kg7 39.Rfd2 d5 40.Re1








40...Nh7 41.Rxe4

And a total collapse of the Black position.

From the stem diagram:








10...Nbd7  11.Rc1  Rd8 12.b4 Bf8 13.g4 Nb6 14.Qd3 Nfd7 15.a3 Nc5 16.Qd2 [16. bc5 wins too] Nca4 17.Nxa4 Nxa4 18.f5 Nc5 19.Qc2 e5 20.Nb3 Nxb3 [20...Nbd7 21. g5] 21.Qxb3 a5 22.bxa5 Qc6 23.Bb6 Be7 24.Qe3 Rf8 25.g5 Kh8 26.c5 dxc5 27.Bxc5 Bxc5 28.Rxc5 Qa4 29.Rfc1 Qe8 30.Qg3 (win) Qe7 31.Rxe5 1–0 even better.

Or, again from the stem diagram above:

10...Nbd7 11.Rc1 Rd8 12.b4 Bf8 13.g4 Nb6 14.g5 Nfd7 15.h4 Nxc4 16.Bxc4 Qxc4 17.Nd5 Qxa2 18.Rf2 Qxf2+ 19.Bxf2 exd5 20.exd5 g6 21.Qe2 Nb8 22.f5 Nd7 23.f6 Ne5 24.Rc7 h6 25.Qc2 b5 26.Bg3 Bg4 27.Nc6 Nxc6 28.Qxc6 Bf5 29.Be1 Bd3 30.Bd2 hxg5 31.hxg5 Bc4 32.Be3 1–0

Machine-like.  All without any ingenious human intervention after g4.

OR:

1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6 5.c4 Nf6 6.Bd3 d6 7.0–0 Be7 8.Nc3 0–0 9.Be3 b6 10.f4








10...Bb7 11.g4 Nc6 12.Nxc6 Bxc6 13.g5 Nd7 14.Qh5 Qe8 15.Qh3 e5 16.f5 f6 17.g6 hxg6 18.c5 b5 19.cxd6 Bxd6 20.Bc2 g5 21.Bb3+ Rf7 22.Rfd1 Bc5 23.Rac1 Bb7 24.Qg3 Rb8 25.Qf2  Bd4 26.Bxf7+ Qxf7 27.Bxd4 exd4 28.Rxd4 Ne5 29.Rcd1 Qh5 30.Rd8+ Rxd8 31.Rxd8+ Kh7 32.a3 a5 33.b4 axb4 34.axb4 Nf3+ 35.Kh1 Ne5 36.Qg3 Nc6 37.Rd7 Ba8 38.Kg1 Nxb4 39.Rd8 Bb7 40.Qb8 Qg4+ [time control] 41.Kf2 Qf4+ 42.Qxf4 gxf4








In full-fledged Capablanca style.  The black f-pawn will be captured and every amateur can play this endgame over the board.

In all lines Black is lost after g4, the only risk move leaving a relatively unprotected white king and advancing on BOTH sides of the board, Black practically not being able to cross the 6th row!  White has full mobility, the bishops can retreat on Ne5 and or Nc5 the rooks slide like skaters in an ice stadium.  Touching each piece just once in the highest tempo possible.  White can allow queen exchange and transit to superior endgames at any arbitrary stage after move 22/23.

It's the meanest opening line I ever saw!

We had B-52 bombers in the old days, this is a mighty C-52 warplane as this Kan line is labeled C-52!   With four b-c f-g pawn jet engines on its enormous wings, it descends on the board and pushes all the black wood into the abyss.  Unholy!

All right, the innocent cliché move ...e6 is a book move.  Nothing wrong with it at first sight.  Switch off the book.  Will It play e6?  NO!  Consistently Fritz will play g6!  It knows that probably in all lines after ...e6 Black is lost.  So it is a blunder!?  THAT early in the game?  Yes.  I had a hard time winning against the non-book g6-line but I did.  As follows:

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Bd3 g6 6.c4 Bg7 7.Nc3 0–0 8.0–0 Nc6 9.Nxc6 bxc6 10.Be2








Typical Yugoslav-attack strategy with f3/g4/h4 and 0-0-0 without c4 for White is not effective.  Black can afford the fianchetto castle because White loses tempi having to touch the light-squared bishop twice - it will go to either e2 or b5.  In case of Bb5 and Nb3 the light pieces are sitting ducks for the usual a6/b5/b4/a5 black pawn storm backed up by ...Bg7 and heavy queen/rook artillery.

10...Rb8 11.Rb1 Qa5 12.Be3 Rd8 13.f4 h6 14.Kh1 Nd7 15.Rf3 Kh8 16.Bd2 Qc7 17.b4 Nb6 18.f5 Kg8 19.Qc1 g5 20.h4 g4 21.Bxh6 Bf6 22.Rg3








Once again: White is on the offensive on both sides of the board:

22...Nd7 23.Qf4 Ne5 24.Bxg4 Kh7 25.Be2 Re8 26.Bg5 Bh8 27.b5 Rg8 28.Qf2 e6 29.a4 a6 30.b6 Qb7 31.c5 f6 32.cxd6 exf5 33.Bf4 Rxg3 34.Bxg3 f4 35.Bxf4 Qd7 36.Bxe5 fxe5 37.Qf8 Bg7 38.Qe7 Kh6 39.b7 Qxe7 40.dxe7 time control  1–0

In similar lines White wins after besieging the black a-pawn and advancing his a-b connected team while keeping a pistol on the head of the black king all the time.

Computers can defend better then Iron Tigran Petrosian but confronted with this Deus-ex-Machina line Black is helpless without White running major risks whatsoever.  Rendering me a futile rebel without a cause with my high-risk philosophy!

All this kept me in a transparent trance for days in the Amsterdam canal décor.

Good chess defies gravity too.

Maybe Fischer was wrong!  Maybe the game is theoretically lost for Black!?

Then again, maybe not.

Switch off the books.  Set up the pieces for the first white move.  Play 1.e4.  Wait.  What will It do?  1...e5!

Play 1.d4. What will it do?  1...d5!  In other words: maybe all SYMMETRIC ANSWERS can be drawn by Black and maybe ALL ASYMMETRIC Black answers, the Sicilian, French, Caro-Kann, etc., are eventually lost for Black!?

Set up 1.c4.  Will it go 1...c5?  NO!  It goes 1.c4 e5, the English Opening, restoring symmetry after e4 for White.  1.c4 c5 can be readily transposed to a Sicilian and we already know that after c4, Black will lose.

I leave you with this proposition:

1.c4 is the key to the ultimate solution of the classic chess game!?

IS THERE A LAST STAND FOR BLACK!?

No worries.  We can resort to shuffle chess.  We will have to eventually.  And the man who probably saw all this coming now is laughing at me hovering in His heavenly heathen Wodan seat close to the North Pole!

For the record: Fischer lost THREE times against Geller, twice with White in overly-audacious miniature Sicilians.  Euwe noted that at the time Geller probably would have been the best contender in a match against Fischer in the turmoil of the Cold War era, trying to keep the world title in the Soviet camp.  Efim the Well-Spoken One.  Maybe so.

Chessville Weekly once published a photograph of The Holy Trinity of Chess.  Clear to me now: Fischer the mad genius (Last-of-the-Mohicans), Geller, the supremely cool-headed pressure player and the ultimate stubborn Black defender: Petrosian.

All three of Them with broad grins.

The computers will play stronger and stronger, reaching 10-20 moves in the opening in a flash within the next 10 years.  In case professional grandmasters or MAMS-correspondence players (whoever comes first) will busy themselves with rectifying all the weaker 20th century book lines for White.  I think wins for Black in asymmetric positions will be history.  It may be impossible to store a complete map of the opening variation jungle in a human brain; for computer memory capacity it is a piece of cake.

My advice for brave machine-slayers prize fighters: ALWAYS draw with Black with symmetry and playing White provoke with 1.e4 the non-e5 (book) answers.  And sharpen up the open games!  Back to 19th-century romantics after all?
