Re: On-line engine blitz tourney July

Fun tournament, mine was with no opening book, no threads code and came in the bottom half on its first outing, but I quite liked this game (playing white). Not sure how sound was 12 Nxd4, the game flashes by too fast to analyse in real time, but I figured the exchange sac was on the cards at that ...

Re: Open Swiss Edition III

It is strange of course, I have analyzed the position in another computer and the first thing Delocto sees is Rf2, then it changes to Qe6 and then it returns to Rf2. Other engines like Komodo don't even contemplate Rf2 at first. Qe6 is definitely the best move. But I can't find any engine that give...

Re: Open Swiss Edition III

I think there is some nasty bug in Delocto. In this position: 6k1/pq2pr1p/3p2pB/4b3/1p4P1/1Q3b2/PPP5/1K1R1R2 w - - 0 26 It played 26.Rf2? with a score of +4.59 at depth 25??? Myrddin happily responded with 26...Bg3 and a draw score. Delocto replied with 27.Rff1 and a score of +5.88! :? Then after 27...

Re: Open Swiss Edition III

Actually there is no "resign" command in the WB protocol. Engines tell the GUI that they do not continue to play by sending RESULTSTRING {COMMENT} where RESULTSTRING is 1-0, 0-1, or 1/2-1/2, and {COMMENT} is optional. E.g. if the engine plays White and resigns it may send: 0-1 {White resigns} The G...

Re: How good is your engine?

The objective is to get the pawn to become queen while preventing the knight from taking it. This is how my engine handled it in less than 1 second! Spitter 2.1 X64: How does your engine do with this? It's another Stockfish killer. rk6/p1r3p1/P3B1Kp/1p2B3/8/8/8/8 w - - 0 1 Well my modest engine sol...

Re: Open Swiss Edition III

- Resign is set to -5 for 3 consecutive moves where able. Hi Sergio, what command will be send to the engine in order to let it resign? I would like to implement it (winboard/xboard protocol) Thanks! It may depend on the GUI, but I would assume that it will simply send a "result" command, telling t...
