Up Topic The Rybka Lounge / Opening Books / Gambits only! A new ChessBase book for engine-engine testing
- - By Venator (Silver) [nl] Date 2015-06-12 07:10
Dear chess friends!

I offer another ChessBase book for free download, a book that contains only gambit lines: GambitLines.ctg. Down below a few games as a sample.

Some info from the readme file:

"GambitLines.ctg is an openingbook that can be used in the ChessBase GUI. It is meant for engine-engine testing. The book contains gambit lines only: one side has a (small) material
advantage, the other side has to prove compensation. Why a book with only gambit lines? Most available (commercial) opening books focus on the most topical, most played and most popular chess openings, like the Sicilian Defence, the Ruy Lopez, the Queen’s gambit, the Nimzo-Indian and so forth. These openings are very solid and widely used. Gambits were very popular a long time ago, but nowadays most of these gambits are not actively played. Not in human games, not in computer games. Gambits are very interesting, though: they can lead to very sharp and interesting play. GambitLines.ctg will feed the engines with such lines, forcing them to find compensation or to defend accurately.  From time to time the engines will be engaged in very complicated, sharp and irrational battles, that you will not find when solid openings are used.

It is strongly recommended to use the GambitLines.ctg book for both engines in an engine-engine match."

The following sample games were played by a friend of mine (as I don't own Komodo).

An absolute shocker was the following game, in which Stockfish was able to beat Komodo in just 19 moves!

Another King's gambit, in which Stockfish is down two pieces, but has a massive pawn wall to harrass Komodo's king. Komodo strikes back with a nice queen sacrifice:
