The Sherwin50.pgn test set

[Michael Sherwin]

Features:
Max, one set of pawns exchanged.
No pieces exchanged.
Rybka checked!
Very even positions with lots of interesting play!
Good for beta version testing!

I hope this test set is interesting!

I have made no attempt to play percentages. Just playable positions a lot with subtle differeances in pawn structure or piece placement. Especially in the QG/Slave complex.

Albert Silver position 29 is in your set:

[Michael Sherwin]

I did not check for duplication. I am glad that that is the only position duplicated!

[Rubinus]

Hi Michael.

Over short.
E.G.
1) Greco - none engine not play 7.Nc3, 7.Bd2 not interesting.
Better: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.ed5 (idea Nxd5?! 6.d4! and 7.Nxf7 or 6.Nxf7)

2)French exchange -
+ 4.c4, or 3.Nc3 Bb4 4.ed5 ed5 5.Qf3 (Larsen-Portisch)

[Rubinus]

My other concepts:

3)
1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.exd6 exd6 6.Nc3 Be7 7.Be2 O-O 8.Nf3 * -> 5.f4 de5 6.fe5

4)
1.e4 c5 2.Nf3 d6 3.Bb5+ * -> 3.c3, or 2.Nc3 Nc6 3.f4 (Smarthink book)

5)
1.e4 e5 2.d4 exd4 3.Qxd4 (Zap!chess book ...) Nc6 4.Qe3 * -> 3.c3!? (dc3 4.Bc4 cb2 5.Bxb2 d5 6.Bxd5 Nf6 7.Bxf7+ Kxf7 8.Qxd8 Bb4 9.Qd2 Bxd2+ 10.Nxd2 -> interest very asymetric pawns).

[Michael Sherwin]

Hi Pavel,

I have given some thought to your suggestions. And I agree that they are more interesting from the point of view of a human that is watching the games. However, most authors do not watch the games and their interest lies only in the number of points their engine has at the end of the test and which positions their engine does poorly at.

Also I wanted a test set that engine authors of all strength levels could feel comfortable with that do not require concepts to play that they do not have.

However, I will be refining the test set as time goes on and I will test your suggestions for inclusion.

Thanks,
Mike

Hi Michael.

1) Greco - none engine not play 7.Nc3, 7.Bd2 not interesting.
Better: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.ed5 (idea Nxd5?! 6.d4! and 7.Nxf7 or 6.Nxf7)

Actually, 6.Nxf7?? was refuted last year in a NIC Yearbook, (although the key move is hard to find), while 6.d4 Be6! is only a slight advantage for white. It's definitely a playable position and not a trap.

[Michael Sherwin]

Some of the QG/Slav positions can possibly transpose to other positions in the set. I will be correcting this shortly.
