Movei FRC problem 2

[Uri Blass]

Hi Volker,

FRC works only in the UCI mode. You could always use the Polyglot if you want to run it under WB...

Thanks. I'll try it soon. I'm thinking about a good test setup for FRC. The version for "normal" chess works fine with wine under linux and performed well here:

Test conditons look here.

I tested the FRC version under Arena 1.1 only...

Uh oh, let's hope it works with xboard too. Arena does not work properly under wine/linux.

I know for sure it doesn't work under Shredder Classic (can't understand why SMK decided to re-invent the wheel).

The confusion about the different notation styles are a big handicap for FRC. However, the discussion about it took place between grown-up people. Unfortunately some characteristics of that discussion have been ignorance on the one side and obstinacy on the other.

Nothing unusual in this world and in online forums in particular, but a nuisance in any case.

I want to know if there are engines that can play FRC not as UCI engines so I may test movei as winboard FRC engine under winboard or under arena.

I am going to implement the UCI protocol but the problem is that
the UCI protocol does not give me information about the time control and as I explained in another thread it means that I cannot implement smart time management.

AICE does. I'm not sure about Spike. Polyglot works well in this regard too.

Can't that be tested separately? I read your other post and the first thing I asked me was: who plays at 40 moves in 2 hours and 1 minute for the rest of the game? Of course it's nice a program can handle this, but is it really necessary?

For developing/testing it seems to be a possibility to use only those FRC start positions in which king and rooks stand on the same squares as in normal chess. There are 16 of this positions IIRC. Then you can use all winboard engine which support board setup.

it is only an extreme case to demonstrate the point but I think that even in time control of 2 hours/60 moves+30 minutes for the rest of the game(time control that was used in WCCC) it may be better not to use all the 2 hours for the first 60 moves.

I tried Aice and it does not work for me under winboard(I did not try to use polyglot because polyglot is only for UCI engines).

I could make it start a game simply by copy fen paste fen but winboard claimed illegal move when aice tried to play long castle.


My winboard_x is from 29.1.2006 and I wonder if I use the latest version

Sorry for the impertinent question: are you sure winboard complains? If "check leaglity" is enabled and your engine rejects the move then it looks like winboard rejects the move when if fact it has been rejected by the engine.

I can add that I could play movei in FRC against aice under arena.
both movei and aice castled with no problem.

Hi Volker and Uri,

Both of your posts may indicate that WB or Polyglot do not accept a castling move specified with the letter 'O'. Maybe they expect castling moves to use '0' (number zero). Just guessing.

I will test Polyglot/WB combination for Naum in a day or two, and if there is a problem it will be fixed quickly.

Alex

[Uri Blass]

Aice is using the letter 'O 'but movei is using number '0'

It seems to me that the problem is not O or 0
arena understand both.

It seems that the problem is simply that winboard without polyglot translate castling to e1g1 or e1c1

I can add that I think before giving up and deciding that a move is illegal move to check if it is e1g1 or e1c1 and in case that it is e1g1 to translate it to short castling and in case that it is e1c1 to translate it to long castling

Of course the same is going to hold for e8g8 and e8c8

Uri

[Uri Blass]

In second thought I am not going to support buggy winboard for the simple reason that it is impossible to do it for all cases.

The problem is that the engine has no way to know if e1g1 is castling(by king from d1 to g1 and rook from h1 to f1) or simply queen from e1 to g1.

I use Tord's version of xboard. I guess the problem has been discussed in detail in this thread.

Volker

[Uri Blass]

I can add that movei accept both O o and 0

The problem is what I should print
printing "0" at least work under arena.

Glaurung solve the problem by simply not priniting king take rook
but I want to support winboard first.

I want to know if there are engines that can play FRC not as UCI engines so I may test movei as winboard FRC engine under winboard or under arena.

the Baron plays FRC as a winboard engine.
But the FRC implementations in winboard are not very stable at the moment. I changed a few lines in winboard_x to make it work at ICC but haven't tested it with engine/engine games or human/engine games.

And it is getting worse it seems. Meanwhile I have in my collection:

==> the original source code
==> the xboard FRC version by Fabien and Tord
==> Milix's variation of it
==> Alessandro's winboard_x version
==> the source code with your changes

Some of these in two variations with a small extension from my side to kill the engine process if it doesn't terminate correctly.

IMO it would be very useful if someone combines these different branches.

As far as I know the code changes of Fabien and Tord are also included in winboard_x. I also sent my changes to Alessandro. I just hope he can find the time to do something with it.
