2018-04-28	Datr	I find these long problems useful, I have also noticed that there are often many almost equivalent defensive lines, I don't see this as a problem, what it does mean is one can't possible see all the moves from start to finish, but can play the problem on a move by move basis, which I do find useful. It becomes a problem when the attacking side has moves of a similar evaluation especially when the best move is totally missed by the engine. Every move on the attacking side should, ideally be significantly better than all other moves, but I do find "There is a better move" a reasonable compromise in most cases. It is interesting to note that you both thought Qxa7 was a better move, even though you couldn't see the full line to mate. I think this site develops this type of "vision" which of course is very useful OTB.
2018-04-28	Toroksm	You are right Datr, the real issue is indeed that Qxa7 did not even fall in the 'There is a better move' category. But still, should a tactics problem continue, when there are some moves so close in evaluation, that even the engine may miss which is the best one? The difference here was a mate in 17 vs. a mate in 18, according to Paprazzo95 and Stockfish 8. Is this the real intention to require this kind of exactitude as a "minor" part of a tactics problem? Just to compare: number of required moves in mate problems do not go over 4, and sometimes those mate problems are still not easy. By the way, you mentioned time: Is the time given for "creating" a problem proportional to the required number of moves?
2018-04-27	Datr	I agree t94969 needs disabling. I don't think the fault lies in the number of move I think it lies in the fact that it mis-evaluated 9. Qxa7, this is probably to do with the time the algorithm has to "create" a problem, given more time it probably would,'t have made this error. My Stockfish 8 had to be shown the move 9. Qxa7, it didn't consider it initially, eventually it does see it as the best move.
2018-04-27	Toroksm	Zuril: t94969 needs disabling. How is the required move number determined for a correct solution? This problem could have been really good, if it had not required 10 moves, but 8 instead. An error was discovered in the 9th move (see the comments to the problem). In most cases, the number of the required moves are determined correctly, providing a good experience in general to solve problems. But there are some rare exceptions, including this one. That's why I'm curious about it. I guess there is an algorithm that decides deterministically, based on the computer evaluations of the possible moves, but maybe some tuning of that algorithm would eliminate errors like this.

2018-04-24	Datr	Zuril: Please read comments attached to t50818. Also please could you clarify, has Gary been banned once or more times.

2018-04-23	Mabor	I hope you are jocking :-D
2018-04-21	Zuril	m42955 and t104495 disabled. Thanks. I wrote to Gary to come back since you miss it ;-)
2018-04-20	Mabor	No, please don't: boring life is more than welcomed :-)
2018-04-10	Dmedved	Please bring back Gary, life has become so boring.
2018-04-10	Datr	Zuril: Please disable t104495.
2018-04-10	Toroksm	Zuril: m42955 needs disabling.
2018-03-28	Zuril	No the bug wasn't related to the time limit. The timeout is a standard feature of any web server, if you do nothing for some time it logout you. This is a new server I don't know if the timeout is the same as the old one. I think to be sure is better to write on notepad and then past the full comment on ideachess

2018-03-28	Datr	Zuril: Was the bug related to a time limit on comments? If so, thanks. If not, I have often written length comments that have taken considerable time and when I come to save them they haven't saved so my efforts have been lost. Is there are time limit, if so could it be lengthened. Thanks Datr.
2018-03-27	Zuril	I solved a bug in adding and editing comments to the exercises

2018-03-25	Zuril	I migrated ideachess on a new server upgrading php from 5.4 to 7 and using Nginx instead of Apache web server

2018-01-16	Chessreaper	Why cant i look at my older problems? Is it a payed feature?
