new Rodent book

Post by PK »

hi all,

I have just uploaded improved version of Polyglot book for Rodent chess engine. It is available at:

http://www.pkoziol.cal24.pl/rodent/rodent_download.htm

Probably still too weak for a truly competitive book, but contains a couple of interesting lines.

A couple of highlights:

- dislikes Petroff and Qc2 Nimzo-Indian
- likes 4.e3 with early Nge2 in Nimzo-Indian, occasionally plays 3.c3 in Sicilian and d3 in Ruy Lopez
- I tried to avoid short lines whenever possible, using big sample of long drawn games by players of at least IM strength
- in manually checked lines (about 1.500) moves with probability < 10% were pruned

Known defects:

- French, King's Indian and especially Gruenfeld weren't checked manually as thoroughly as other lines
- needs more refutations against obscure lines (some stuff has been t added manually, but not enough)

Have fun!
