Book, book, what's the fuss? and some Fruit

[Peter Berger]

Two games Fruit-Yace.

Fruit played on a PIV 3.2GHz HT, 512MB Hash, Shredder Classic interface.
Yace played on Athlon 64 3200+(2.0GHz), 256MB Hash, WinBoard 4.2.7, egtb and bb.
Games in 1 hour with 10 seconds increment/move.

Fruit clearly is no fruit at all, an amazing newcomer.

Book is a fascinating topic for me - the question if a default PGN book is to any advantage is open IMHO.

Game 1 sees Yace using its opening book playing a horrible setup. Yace was out of book after 4. c4 . Some evil moves to follow: 4. e6?, 5. Sc6?, 8. Bb4? . The position after 10. a3 should be nearly won for Fruit IMHO. But then the opponent was Yace after all, that is known to be a bitch . 12. g4 should be dubious. 14. ..Bd7!? is a very fascinating move. Quite a game to watch with the fascinating material imbalance.

Game 2 was interesting too. It might be interpreted as a strong argument in favour of books, but I wouldn't agree. Yace out of book after black's fourth move. 5. Nce2 is a great move and Fruit just didn't understand that - eval, not book IMO.

Have fun.
Peter
