The Sorcerer's Apprentice

Post by Lyudmil Tsvetkov »

Here is a game played by Bronstein in 1956.

[pgn][Event "Olympiad"]
[Site "Moscow URS"]
[Date "1956.??.??"]
[EventDate "?"]
[Round "5"]
[Result "1-0"]
[White "David Bronstein"]
[Black "Ernst Rojahn"]
[ECO "C58"]
[WhiteElo "?"]
[BlackElo "?"]
[PlyCount "75"]

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Na5 6. d3 h6
7. Nf3 e4 8. dxe4 Nxc4 9. Qd4 Nb6 10. c4 c5 11. Qd3 Bg4
12. Nbd2 Be7 13. O-O O-O 14. Ne5 Bh5 15. b3 Nbd7 16. Bb2 Nxe5

32. g6 Bxg6 33. fxg6 b5 34. d6 Qb6 35. d7 Nxd7 36. exd7 Rcd8
37. Nxf6 Qc6+ 38. Qg2 1-0

[/pgn]

Of course, Bronstein was not simply a tactical genius, as he is most commonly labeled, but also a very profound positional player. Actually, I think Bronstein is the best theoretician, even better than Fischer.

As you might know, The Sorcerer's Apprentice is the name of a famous book by David Bronstein.

[d]r1bqkb1r/ppp2pp1/5n1p/3P4/2nQP3/5N2/PPP2PPP/RNB1K2R b KQkq - 1 9

This is a position arisen out of the opening.

How many engines recognise white is winning above?

PS. Please, do not tell me there are engines that would favour black.

White has 2-3 full pawns advantage above.

Do I see clearly that SF gives more than a pawn black advantage, or maybe this is just a hallucination?

SF is very firm in it's belief that black has a sharp advantage, Dr. Tsvetkov.

This sac is very dubious, so no surprise black is favored.

There are two lines that seem to favor black,
a) Nd6 (rather than Nb6) followed by Nxfe4, which is very tactical, and
b) after c4, Nbd7 with the idea of deploying the B to c5 and Qe7.

In the game, Black messed it up by moving the Q the K side, trapping it. There were plenty of opportunities to improve.

And you are very firm to positively contribute to all my threads, and also to PyChess glorification.

Thanks a lot.

Maybe you will post some SF output, won't you?

What do you mean dubious?

As said, white has 3 full pawns advantage above, supposedly, this will suffice for a win.

Did not you at least like the game?

Not at all, no opportunities to improve at all, white is simply winning that.

I could play this game 100 times against SF or any other engine, and black will not draw even a single game.

Btw., if you look at the game, this is a very nice example of the strength of long chains, but SF refuses to implement them.

I think that anyone wanting to learn very good opening theory, the best possible, in no time at all, should only take a look at all Bronstein games - much better than checking some large databases containing games of all sorts and players.

If you would like to learn opening theory, just look at Bronstein games, second best theoretician would be Fischer, and Kasparov is far behind.

The advantage is more than a pawn at the present depth, if Black plays Nd6. But I am trying to get it over 1.12 :) It has dropped to 1.08 again:

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Dr. Tsvetkov, I hope you don't think I am being overly inquisitive but...in your much venerable opinion, who is the greatest player in history?
