Re: Deep Hiarcs 15.....!?!?

Hiarcs Chess Explorer is a nice clean quickly loading GUI on Mac OSX, and that is why I bought it. Hosts other UCI engines well. I see that the database features are planned to be enhanced in version 2, which is nice - I just hope that it doesn't try to cram every possible feature in (there's ChessB...

No, but you will have to buy me a faster computer ;)

Re: Gandalf cross

You amaze me with your stats, how are you able to do that? You provide very valuable information. It's very easy if you have a large database and some good software that allows sophisticated queries. SCID will do it, but Chess Assistant and Chessbase are solid commerical options. Large databases of...

Re: Gandalf cross

Fischer used to fianchettoe kingside in more than half of his games. Only when black. Pulling up Fischer's games in a database: As white: 558 games, of which 66 feature a king-side fianchetto (defined as a bishop on g2 and a pawn on g3 on or before move 15) As black: 396 games, of which 236 feature...

Re: Gandalf cross

The problem with Joerg's patch is not that SF does not recognise the importance of kingside fianchettoes, when they are available; I tried this many times, and, whenever I fianchettoe the king bishop instead of SF, it very soon gives that line as better than other lines it likes to choose. But you ...

Re: Gandalf cross

Btw, Vince, just to ask you: did you try implementing the hotspots rule as a single available pawn structure with closed center: d4,e5,g5 white pawns, d5,e6,f7,g6 black pawns? I think this might be essential for the success of the patch. An open center or lack of a backward pawn on f7 might lead yo...

Re: Gandalf cross

. I thought the hotspot idea failed at VSTC in your local testing. In any case, if my concern is a valid one, the idea should prove better as TC increases. If not, then maybe my concerns about fishtest are unfounded. I can see why you might have got the wrong end of the stick. Hotspot passed at VST...

Re: Gandalf cross

Yes, your points are quite valid. And still I wonder if, for example, the "hotspot bonus" idea might prove positive were it possible to test at more standard time controls. I mean, if the engine doesn't have time to find the "point" of the position you've told it to choose, of course that choice wi...

Re: SF book???

No, that will not work. In an 8-move book, all kingside fianchettoes will already have been made by move 8, or the book will simply not have them. You can not introduce a kingside fianchettoe with an 8-move long book.. I'm not sure what you are trying to achieve here. If you want the engine to appr...
