Re: Elements of the ULTIMATE Chess GUI?

So winboard.INI has been done away with? Providing the same information on the command line does not count. Don't get me wrong. I think winboard is fabulous and I use it a lot. And configurations are broadly improved. But his complaint makes sense to me unless I have missed new developments (not un...

Re: Elements of the ULTIMATE Chess GUI?

- THINGS THAT ARE ANNOYING TO AVOID - don't lag and don't cause losses on time, like Arena does - don't force user to work on text files, hand-type engine paths etc. like Winboard does - exit gracefully, killing the engine processes (problems with Arena again) This is pure and malicious libel. WinB...

Re: Chess engines for circular chess boards

Note that even an L description with only orthogonal steps (i.e. through cell edges) of the Knight move is ambiguous if you don't specify whether the short or long leg of the L has to be taken first. In the picture on your website you seem to mix these two moves: vertical (= forward or backward) mov...

Re: On-line engine blitz tourney April

That you use XBoard suggests you run under Linux. Note that in Linux you cannot simply run binaries in the current directory by writig their filename; you have to prefix them with "./" . So if "sapeli" and "timeseal" are not globaly known commands (e.g. because you installed them in /usr/bin), you m...

Re: On-line engine blitz tourney April

You can test the workings of the engine in individual games by logging in as guest, but for the actual tourney you will need a registered acount, or mamer would not allow you to join. (It wats to check if the rating is in range, and unregistered players have no rating.) If you PM me an e-mail addres...

Re: Chess engines for circular chess boards

Without the bottom plane proposed by Daniel it is of course not topologically equivalent to a sphere. But it is part of a cube with 'rounded' corners and edges (like with good dice), the triangles being the corners, the faces being 4x4 and the edges being 4x1 strips between them. When I was taught t...

Re: Stockfish misevaluations:

It could be useful to look at the position at the end of the PV, to see what exactly it considers +5.38, and whether this is an obvious mis-evaluation.

Re: Stockfish misevaluations:

You could patch the eval of Stockfish a little in this particular position by scaling the stronger side down for having all pawns locked (after giving b5). The 'lantern' formation on the right is a well known 'indirectly' blocked formation. You could also put the eval at 0 (or scale it down by a fa...

Re: Chess engines for circular chess boards

The Jocly AI should have no problems doing this. (The Jocly UI is another matter, though.) There the move generator is based on a 3d array (actually an array of arrays of arrays), graph[fromSqr][direction][range]. The 'direction' actually is an arbitrary sequence number, and for all directions all r...
