2019-05-05 Toroksm Zuril: Is it possible to enable other means of input rather than dragging the moves? This leads to not intended errors, which is very disappointing after having found the good solution. I can think of 2 possibilities:
1. Clicking on the "from" and "to" squares
2. Using the keyboard to type the "from" and "to" squares.
Hope that others would also find this useful, and that it would not be that great effort to implement.

2019-03-27 Toroksm Zuril: t105855 needs cutting after white's 8th move or disabling, please see the comments.
2019-03-26 Datr Zuril: The en passant flag is confusing to some new players, they don't understand that it means "The last move was f7-f5" especially in 5he cases where an enpassant capture isn't possible.

I think changing 'the flag from "en passant f6" to "The last move was f7-f5" might make the flag easier to understand.
2019-03-05 Datr Zuril please see comment t113612, some players RD increased by 30 in one day.

2018-06-12 Datr Zuril I am currently using my tablet to solve problems. The problem I have is when I drag a piece up the board the whole page also drags, so this makes it difficult to move pieces. Is it possible to stop the page moving? Some sites have a piece move option 'drag and drop or click on the start square and the destination square. The second option would solve the problem on my tablet.

2018-05-13 Paparazzo95 why does the system keep throwing me back into the limbo of the inactive players? I do prefer to play many problems in the practice section rather than in the ELO section, but still my ELO problems are quite a few more than 10 per months. Has something changed over the past couple of months?

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.
