Re: RSIF as alternative to armageddon

If we are to eliminate draws, which is the theme of this thread, then draws either have to be awarded based on some aspect of the position (or game history) or else just arbitrarily awarded to one color. I took from the title, that the elimination of draws was a way of solving ties, without having ...

Re: RSIF as alternative to armageddon

Note that with the "bare king loses" rule, you cannot ever have king vs king, because one side has a bare king before the other. Presumably White would usually be in a position to control who has the bare king most of the time. One sensible variant would be that if Black is left with a bare king, i...

Re: RSIF as alternative to armageddon

A good estimate of what the score would look like for any given level of player is to just look at the score under current rules with the draws tossed out. With engines, it's not so easy as the results depend heavily on what opening book is used. I've assumed all along the use of strong books, much...

Re: RSIF as alternative to armageddon

The 55-45 spread would be very much wider if all draws went to the "superior" side (reasonably defined), and the margin would grow with the strength of the players. It might be 60-40 with ordinary masters, 65-35 with GMs, 70-30 with super-GMs, 75-25 with World Champions, and 90-10 with top engines....

Re: future of top engines:how much more elo?

What is wrong with the SF10 testing? Stockfish 9 64-bit 4CPU has a rating of 3547 with error bars of +12/−12 while Stockfish 10 64-bit 4CPU has 3546 with the same error margin. That means that even in the best case scenario, SF10 would rise to 23 Elo points ahead of SF9. That's less than the differ...

Re: future of top engines:how much more elo?

I guess all these discussions are useless, the rating lists are built from volunteer work and what those volunteers want to test (that's why Stockfish 9 tops the 40/4 list... I'd say the latter is a different problem which has to do with credibility. I pointed out to Graham from the get go (of SF10...

Re: RSIF as alternative to armageddon

we have to give Black something or the game would be an obviously forced win by White (even if you can't prove that) You can't prove it, but a serious test should leave little doubt as to how much black's position is worsened. Before trying to fix something, we should make sure it's broken, don't y...

Re: RSIF as alternative to armageddon

someone would have to redo tablebases to be consistent with my stalemate/bare king rule. [...] This would help a little towards equalizing the game, since probably Black has some advantage overall with my rules. If syzygy doesn't offer a win in sight, it will only provide draw suggestions, a modifi...

Re: RSIF as alternative to armageddon

1. Three time repetition is illegal. 2. Stalemate is a loss for the stalemated side. (old rule) 3. Bare King loses. (old rule) 4. Fifty move rule is a win for Black. 1. Agreed, I don't even see the reason for the 1st and 2nd repetition, but the less is changed the better, I guess. 2. Obviously. Alt...
