  |

The following set of EPD positions have the following characteristics:
1. After a deep analysis by one or more very strong chess engines, the centipawn score was exactly zero.
2. These positions are all played frequently (at least 100 games in my database of high end games)
3. These positions all have lots of sensible alternative moves
4. None of these positions is a forced draw
I have included a predicted move (pm), which is the move that the computer analysis thought was best. Somtimes there are alternative moves that also have a score of exactly zero.

There is some overlap with other test suites, as these positions (for instance) are also found in the Hyatt Quiet test suite:

I don't want "quiet" or "==0" type positions for testing. I want a cross-section of what I might expect to encounter in real games. Of particular interest is positions with some sort of imbalance giving both sides chances to play for a win... That is, I want positions that are not dead lost or won, but also not dead even, which you rarely see in a chess game. |

Do you have a collection of such positions that you will share? |

These are all from real games and are all frequently played. Both sides have chances to win. They are selected because neither white nor black has a clear advantage, so the normal imbalance for white is reduced. |

On my ftp box. The set of positions I use in my cluster testing. I think there are 4,000 in total, randomized so that you can pick the first 500 if that's all you want...
The filename is "openings.epd" |

Bert Gower and I discovered years ago that we didn't want to steer the game toward "equal" positions out of the book. We preferred positions where the eval jumped around as the search went deeper, where we had some plusses and minuses (really equal positions are way too drawish). For example, a weak queenside pawn structure in return for some king-side attacking chances. Each side then has something to "play with" and the better evaluation and search will usually find a way to exploit its own advantage without letting the opponent take advantage of his plusses... |

Most of the positions in this collection are played literally thousands of times in real games. I guess that they have chances for both sides almost all the time. However, like every other collection of starting positions, it will have some drawbacks. |

Are they available as PGNs?
One of the good thing about this set, is that if you find that your engine is consistently losing in one of this positions compared to others, there something to take a look at.
I observed this behavior by accident a while ago. The first position I had, I think from Nunn, Gaviota almost lost every game. Since it was the first, I almost always looked at the game after I started gauntlets. It allowed to spot a terrible tuning I had for passed pawns. I always pondered the idea to make this "hole-hunting" in openings more systematic.

Probably the best way is to mix significant imbalanced positions (static vs. dynamic, static vs. different static, dynamic vs. different dynamic) with some not so imbalanced positions (quiet?) since BOTH do occur in real games. This not only gives a more accurate feeling of which engine is stronger but it can tell where lies the more strength.
I would also test early endgame positions. Early endgame strength is also a must for analysis. |
