Can there be more than 1 solution to a puzzle?

Chess.com tactics usually have more than one winning line. I think it's unfair to have people lose points for finding a winning, but not best, line. Thus I wonder, do chess.com tactis have More than one solution to them?

yeah, I have wondered about that too

Yes, they do. The point is not to care too much about points, but if you learn how to make the best moves as much as you can and keep learning the beauty of chess, it will help you to have an easy winning position. I rather have chess.com tactics teach me a very good puzzle even if I got the wrong move and learn how to play like a master rather than getting just my points up!

Don't worry, we all make mistakes and we will all improve in no time, thanks for being one of my favorite users here. Keep the amazing work.

Best regards, Eric.

Yeah, it is really annoying to lose points for finding a winning, but not the best line.

I barely ever do tactics lol

The tactics should not have move than one winning line. Or, if they do, the line the tactic is looking for is a lot better than any other line. For example, mates are better than material.

That isn't to say some tactics are not more ambiguous. In that case, the tactic should be reported if it really does have more than one essentially equal line.

Some problems DO have more than one solution. But does it matter? The point is for you to find the best solution, not just a good or great solution. Of course there are times there is the option of winning a queen or rook, and easily win the game. But that's not always the best solution. Like Martin said, a mate solution is better. I used to be annoyed when I would find a great solution and still get it wrong. But now I dont care, because I would rather lose points and know how to play better than win points for a really good solution that isn't the best.

Chess.com has a lots of bad tactics. People try to excuse them but they are bad.

Yep

Sometimes I do a tactic and I think that two lines do the exact same thing. I play one line and get it wrong, and the other line is correct. Normally when this happens there is a reason why my line doesn't work, but sometimes I can't find why it doesn't work or it is such a hard line to find. and the solve time is like "14 seconds" HOW am I supposed to see this crazy line in 14 SECONDS? 

yes

of course

it is probably

but be careful

and you will win

the only thing you have to do is believe

Its a very common complaint about the tactics trainer.  Not only do you lose for finding a win that is not the computers best move, you don't even get partial credit!  

To make it worse, the trainer will trick you on purpose.  A fork that wins the queen, brilliant!  NOPE YOU LOSE!

On the bright side, there is some value in it, as it is teaching you to evaluate positions more thoroughly.  It also will ingrain in you the very good old chess axiom;

"After you find a good move, look for a better one."

The tactics trainer relies heavily on the evaluation of an engine. There are lots of problems with alternative clear wins. Some line which is evaluated as +2 and an easy win for humans can still be wrong according to the tactics trainer, because the 'best' line is evaluated as +6. That doesn't mean the move is better, only according to the engine. A move which wins faster isn't better. You don't get extra points for winning in less moves. You only need to see a clear win and try to avoid complications if you are winning. This is also the reason self-learning engines may go for slower wins.

Exceptions are moves which waste tempos or lead to repeating the same position. I agree such moves should not be correct.
