Very clever distinction. I support it.

Re: Null move in WinBoard (analysis)

I tend to agree to that, but it is not that obvious how I can enforce it. Even I forbid entering the null move at game level, it would still be possible to 'upgrade' a variation to a game. In fact WinBoard always does that when you open the variation for viewing / editing, so it is not a good idea ...

Re: Null move in WinBoard (analysis)

I now posted an experimental WinBoard version that allows the user to play null-move in Analyze Mode. To play a null move, just click on the clock of the side you want to give the move to. The null move will be stored in the Move History as its SAN form, "pass". This is also what will be saved in P...

Re: How to use null move in Arena?

Let me see if I understand this. You cannot send null moves to an engine; they would refuse them as illegal. So what is needed is to send a new setboard to the engine with the other side to move. The GUI should remain aware that a null move has been done, and still allow you to step through the gam...

Re: How to use null move in Arena?

I don't understand what you mean at all. Doing a null move is by definition the same as giving the turn to the other side in the same position, right? I am a bit confused what you mean by 'same side' and 'opponent'. Say I would be in theopening position, and play a Null move (for white). What would...

Re: How to use null move in Arena?

Nullmove has nothing to do with the followup move. http://en.wikipedia.org/wiki/Null_move "In game theory, a null move is a decision by a player to "pass" (that is, not to make a move) when it is their turn to move." If White plays a move, Black decides not to play, and White plays again. This is a...

Ok, but it does not work. It only makes that engine analize the same position for other side. Null move should suggest the next move for the same side, without considering the opponent´s move.

It seems Null Move has not been implemented correctly in Arena.

Re: Yes, OK, he copied, but was it so esential?

You are right, we have a two different perspectives: For me "the golden egg goose" is Fabien´s "Fruit", not Vas. Vas was like a peasant who find out "the golden egg goose" feeding formula. So, I am not against this peasant´s making his maney, I only support the idea that this peasant should share h...

Re: Yes, OK, he copied, but was it so esential?

I think that, when we make our judgements, we should distinguish Vas and Rybka, because Vas is a human who had and still has his intentions, while Rybka doesn´t. Yes, after the process of reverse engenieering transformation, innocent, without any intention, Rybka has become very importante for the ...
