Re: Why there is no interest in Computer with odds Vs Humans match?

The networks are trained on very fast games, vastly faster than games that would be played at human time limits. So they will play in a way that optimizes win prob. against an opponent much weaker than the level of the network at a realistic time limit. Whether that is above or below the level of N...

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: 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

My point is that either method can be made to produce roughly even white/black results with no draws with enough testing of different variations. Okay then, here's a new one (to be mixed with other conditions): in case of 50 moves without pawn move or capture, the side with least time on the clock ...

Re: RSIF as alternative to armageddon

Got it. At least most ideas can be discarded right away because they're not in the spirit of chess. Perhaps having an engine that knows the new win conditions playing against regular Stockfish would be a way to test this, because if the best moves in normal chess are bad in the new conditions, it c...

Re: RSIF as alternative to armageddon

I agree with lkaufman, it makes no sense to come up with something that produces 50% performance for both sides regardless of strength with 0% drawrate if it ends being very unnatural or boring to play, or it feels arbitrary or wrong. (note I don't care about an alternative to armageddon, I'm seeki...

Re: RSIF as alternative to armageddon

Since stalemate is probably not too common, perhaps just switching it to the Black column would bring the results close to 50-50? Or if the result was then too favorable for Black, making stalemate a loss for whoever had no move might make it about fair. I agree, but it seems premature as Deuterium...

Re: opposite castling armageddon

Regarding removing a7, it feels to me too clearly winning for White, but I haven't tested this, so I could be wrong. White is a significant advantage in chess, and to remove any Black pawn should push this advantage well past the winning margin I would think. Yes, it seems hard to believe. But I am...
