That's right! The WinBoard is SMARTER!

I have been shaping up the documentation of WinBoard, which was also lagging a lot compared to the actual development. Next WinBoard release will have a fully updated help function in its menu. But, as the entire WinBoard manual is a rather unweildly document, it seemed a good idea to have a separat...

Re: Shartranj!

True, according to WB protocol the setboard is not needed here. (At least, I suppose Dabbaba starts with Kings on d1/d8?) The problem is that its opponent (Pulsar) is buggy and needs the setboard, and that there is no way to tell WinBoard to send the setboard only to one engine. But of course we cou...

Re: Shartranj!

Well, it still doesn't work. Seems Dabbaba sends something that is not recognized as a move, as '_' is not recognized by the WinBoard parser as a captital that could be a piece name. So the line _f1-g3 below is simply ignored. So the game hangs, while WinBoard is waiting for a move from Dabbaba. It ...

Re: Shartranj!

I still have problems. Dabbaba won't move. I guess it chokes on the FEN for the initial position, because it has B and Q in it. (Unfortunately I have to play from a setup position, as Pulsar does not use a correct opening array if you let it play without sending a setboard first.) Can you make it su...

Re: Shartranj!

OK, I suspected that the problem would be caused by sending moves in SAN. I am not sure why it did not occur before; I remember I did play Dabbaba against Fairy-Max, and I do't remember having made a version of Fairy-Max using alternate piece names in Shatranj. The problem is that WinBoard uses Elep...

Re: YATT.... (Yet Another Testing Thread)

So -16, -19, -20 and -21. Now I am going to take the three huge pgn files I have, and run em thru BayesElo two at a time changing the name of crafty-22.2 in one to see how the two versions will compare, knowing that they are _identical_ in reality Seems to me that a simple multiplication by 6/5 sho...

Re: Repetition Detection

I think the missed communication occurs in the term "history". Or more precisely "the past". I consider history anything that has happend up to now. Not anything that has happened up to the root of the tree we are searching. I find it more convenient to not make any distinction between whether a po...

Shartranj!

For those interested in variants: I opened my live viewing port to my Chess PC for broadcasting Shatranj games. (You might have to click 'refresh' once to make the game start, first time you browse there.) Currently I am playing 40/5' games of Fairy-Max vs. Pulsar there; I hope to add Dabbaba to the...

Re: testing, 3[code] complete runs now... A stats question..

No, that is not how it works. How you process the data would depend on if the confidence intervals were externally supplied, or derived from the spread in your data itself. When externally supplied, the variances add, meaning the SD gets sqrt(2) larger in the sum of the ratings, and sqrt(2) smaller ...

Re: Repetition Detection

In my terminology, "history" is anything that has happened prior to the current _node_ whether the move was really played or not. OK, that explains the miscommunication. In my terminology 'game' means what was played on the board, 'tree' means what is being searched. I do not consider the nodes fro...
