Maybe it is too easy as it is 1800.

definitely not an 1800 problem

Now a 1941 problem lol

Looking at the wrong problem is the problem here...

every one tries for a check or even worse checkmate

People are probably looking for something more complicated, given its difficulty rating.

-16 first or next move thinking

I spent over 2 minutes looking for a mating sequence of some kind. Nope, wrong line of thought. Got it right eventually . . .

Looking at an average time of 422 seconds I was expecting a little more than a rook. lol

The average time on this one is 6:33. Some other, similar problems that are no less complex run at around 20 seconds. I do not understand those huge differences.

the time is a function of how long it takes people to solve it.  So the players are weird I guess if you are correct :). 

People are definitely out smarted by this simple material gain.  Too funny.

Look at the analysis.  It's not just a simple material gain.  We gain an exchange of knight for rook, but the continued pressure on the king's position leads to more gains and ultimately should lead to a win, even if it's not a quick forced mate.

Down to 1280 but the time is 554 seconds!

100%, 29 seconds.  The average time is ridiculous.

11 seconds!  Woot.  I don't know how I can look at mating sequences here so quickly and efficiently, and correctly take a different line, then miss such easy mate in 1s every once in a while!

Don't get me wrong, if I were in an actual game I would have gotten this easily.  But this is tactics training- how is "take the rook" a tactic? If I'd had to set up the fork, that would have been a tactic.  But something this simple shouldn't qualify, which leads me to look for something else.

Jurgan i agree with you.

but you must see that the last move is of the King , and as tactics trainer showed you the square from where the king moved i.e the king moved because he was under check .

i mean to say there is a reason for the king to move , and you were supposed to catch that clue.

that clue led me to catch it and i did take the rook.

"there is a reason behind every move in chess"

and you were to see that reason.

100% 11 seconds, i guess i can see the easy ones.

I agree with Jurgan. It should have started one move earlier, whern the knight was moved into position to attack both the king and the rook. It's very different to just notice "hey I can take the rook" than to say "If I move this piece, I can setup the opportunity to take the rook one move (or more, depending on the situation) later". The difficult part is setting up the opportunity, not the capture at the end.
