Hi Jef, I've been playing with your gambits book - interesting lines! thank you.
Is there a way to be able to use it in Fritz/chessbase interface via some adapter or such like?

cheers,
Peter

"Is there a way to be able to use it in Fritz/chessbase interface via some adapter or such like?"

yes, you can load any engine (P4 or others) in the Fritz GUI
but then the question is how to use the gambits book as engine book.

Easiest way i presume is to use polyglot(.exe) as engine in the Fritz GUI
and specify the specific engine (eg Patricia 4) in the file polyglot.ini
and as (engine) book eg. gambits.bin (also specified in polyglot.ini)

note i use(d) polyglot with winboard, and have polyglot.ini file like this

[PolyGlot]
EngineDir = /
EngineCommand = patricia_4.exe
Threads = 6
Hash = 512
Book = true
Bookfile = gambits.bin
BookDepth = 14

I wonder what eas score LeelaKnightOdds would have, I calculated it with the tool on 35k training games and I got this, but it's probably not valid to use knigh odds games, "v3a" it's LeelaKnighOdds:

If an engine plays without a knight, this (of course) leads to bogus results in the EAS-Tool, because when the engine wins, it is always a 3-sac (because of the missing knight, that makes the EAS-tool think, a sac of a knight was played). Thats the reason, the 3sac value is so high: 49.43%...

Is there any .abk or . ctg gambit book for Patricia ?
