Re: [computer-go] Differences..
I think we already had that discussion once... These rules completely screw up the notion of territory, as e.g. three single points are better than one three-point-block. My proposal would be a fifth rule that instead of moving you are allowed to return one prisoner. But then, you could as well just allow passes and use (only) stone counting...

Re: [computer-go] Differences..
OK, I see now, with more 1 point eyes for W, W will play into B's 2 areas reducing them to one eye each, and when B can make the capturing moves W can play into its own 1 point eyes, but black can't play into either its own or W's. So, I agree this rule set has very different endgame considerations, and the intuitive Proof on the web page is flawed.

Re: [computer-go] Differences..
I have pondered about this before however that page's proposal furthermore changes the value of captures. If black captures x stones, he may play at these x spots up to x times (depending on other and size of eyes), avaraging one per capture, at the very most. In both [territory + captures] (japanese) versus [territory + live stones] (chinese) rules the value per capture is 2. In order to make the mathematical go more similar one should force the other player to play an additional [difference in captures + signed komi] stones before being declared winners. This would be equivalent to just playing til neither player has legal moves and then count the live stones and komi. The remaining eyes is what chinese also covers. This would also handle Nick Wedd's excellent problem.

http://brooklyngoclub.org/jc/rulesgo.html Is Mathamatical Go a subset of Go as the rules look the same to me as regular go. The rules described here are not mathematical go, but no-pass go. In mathematical go a move consists of a board play or by handing the opponent back a captured stone. This is equivalent to stone scoring. -- Barry Phease mailto:[EMAIL PROTECTED] http://barry.phease.org.nz ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] Differences..
Willing to accept the intuitive proof for the moment, what I see is that the key differences are that 1) there is no komi (black giving points to white for playing first) 2) there is a 2 point penalty for each living group. Otherwise it does look like this is similar to any other Go rules that include positional super-ko. My favorite line: this is a great book if you're a serious mathematician, and a completely baffling one otherwise.

Re: [computer-go] Differences..
Where does the two-point penalty come from? It's not directly stated in the rules, so presumably it emerges from the four simple rules. Actually, neither the two-point penalty nor Komi are meaningful - there is no count to which any penalties could be added or subtracted. Passing, suicide, and superko are prohibited. Available moves eventually diminish to zero. The person with the smallest territory loses, unable to make a legal move.

Re: [computer-go] Differences..
The 2 points per living group comes from the fact that in order to avoid loosing, one plays into one's own territory until down to 2 eyes. While legal to fill one, that leads to capture, so it won't be done. As you say, there is no other counting needed because the smaller territory fills first.

Re: [computer-go] Differences..
So, with these exchanges and just a little more thought, the part of The Alternating Rule that is in red: The first player who cannot put down a stone without breaking a rule loses the game is not the way the game would actually be played. It would be more accurate to add something about choosing not to add another stone, which would cover the decision not to fill one of your own last eyes.
