Suggestion to fix all training puzzles

There are many puzzles where there are good alternate lines that aren't quite as good or don't lead to mate quite as fast as the main line, but are still winning, but the problem fails you if you try them. Lots of people complain about this!

Chesstempo is a website that also has puzzles and it solves this issue in an excellent way. If a move has an evaluation of at least +2, then it's accepted as an alternate move, if not the main solution!

Simply implement this and all complaints about puzzles will stop. It will also be necessary to remove puzzles with too many alternate moves under this change since they aren't good puzzles.

It's not realistic to always demand the absolute best move when there are other moves that also win. In a real timed game it's better to pick the first move you are sure will win, instead of wasting time looking for an even better one.
Berder, here too, when you play a good alternate move it will be accepted, with a pop-up window on the left of your screen encouraging you to find a better one, with no points lost.
And when your move is not fast enough like mate 3 insted of 1 it rejects it.

if you don't like this well it is a puzzle so thats the whole goal finding the best way.

and if you think chesstempo is so good why dont you do it on their site then?
hauteepoque, yes, but not always. That's the problem. I don't know what the criteria are for accepting an alt here, but it's nothing as clearcut as what chesstempo uses (+2 or better evaluation). There are many puzzles with good winning moves that are simply rejected.
The point of puzzles, is not to find one winning variation, but to find the best one.
Not because everything else is wrong but because finding the best variation over and over on different chess boards will actually better you,your visualization and tons of insight on how you can improve you gameplay, tactics and strategy.
If you go for mate in 5 instead of mate in 1 in a chess puzzle it wont matter, but if your on the clock in a tournament and you fail to instantly grasp the situation and give the finishing blow you might run out of time.
Always try to better you self, especially in a game that has to do with pattern recognition, quick and accurate thoughts.
In addition to everything mentioned above I would also state that there are generally some puzzles which assume too many subsequent moves, even after making a major star move that is to be found from the beginning. It seems frustrating to first find a winning set of moves and then miss a shortest mating sequence afterwards in a straightforward position, which you are still required to find for the puzzle to be marked as solved.
For me this is not the real issue although sometimes is annoying..a possible solution would be that when I make a wrong move the engine move after me so that I can easily understand why my move was wrong (or less good). Right now to do that I have to open the analysis and try my variant.

Another nice feature would be to be able download some puzzles in the app so that I can play them in the metro or in the plane where I have no internet.
Or there can simply be more of the "Good move, but you can do better"
Sounds like a big feature request to change everything.
If it does change, make it different from the other sites.

Thinking out of the box: I see two solutions
Solution 1: The puzzle solutions could have a different rating for the different entered results. It's not a pass or fail, like in school, but a chess match with the puzzle. It could continue or end in different ways:
- until it is solved
- plays to the end.
- until the player presses the Solution Button or Change Puzzle Button.
When you stop the puzzle, you get rated for the performance.

Solution 2: Create mini puzzles by removing the none essential pieces. Clear the chessboard so students can learn from the basic tactical puzzle. Derived from real games.

Note: Students first priority is to learn how to isolate a problem. Then when they see the problem, learn how to solve it.

The only short cut is to cut the puzzle into smaller parts to locate the problem. See the defended pieces and the attacked pieces is a great start. Seeing the mobile pieces and the active pieces is another stepping stone. Seeing the key squares is going to be an other challenge. Noticing which sectors of the board are weak or are under attack should not be too hard to learn.

A Master level is attained by knowledge. What you did not learn, will not help you solve a situation that calls for that knowledge. If there was a better move and you did not find it, it is most likely because you are not using the knowledge required to solve the puzzle. Knowledge is like rating points.
Agree, Berder. I like chesstempo for the precision too.

FireWorks #8, yes, that would be very good!... Keeps one thinking and calculating, discarding only the losing moves.
