I mean i sit 26 min to calculated this. Ok maybe im not the sharpest tool in the shed but 13 move deep is not under a min
Ratings and time to solve are based on the history of previous solves. So apparently a number of players are solving correctly and quickly.
How can someone solve this under a minute? 
There is Qa1+ line with several variation like Rxc3 , pawn takes knight
Or there is Rxc3+ right away
There is pawn takes and than bish takes or the queen check line
I know these lines are loseing (By the way the Queen check is just equal) but these are logical lines 3-4-5 moves deep
How can someone see all these and the right mate in 13 under a min??
I tried looking for the puzzle in your history, but apparently you did more after and it isn't in your past 25 attempts.
What? i did this like 20 min ago i only have 1 puzzle after that
This post was right after the puzzle

Ok, it's an 1841 puzzle and only 4 moves long.

Yeah but i got this at 1660 AND the first move is the key but you can do as i said several other moves with several other calculations so if you feel like you can gamble a pawn takes without any check within 50 sec but whats the point doing a puzzle without calculation the lines?
And you cant calculate everything under a min
Change my mind

You don't have to calculate the whole line to go for it, which is what many members are doing. Grab the knight seeing that the white king is in a precarious position since the white queen can't come off that file and the b-pawn is going to quickly fall as well.
It all comes down to how people solve the tactics and many do it quickly, without fully calculating. So that one ends up with a very quick solve time.
Hmm i dont know.
I always do checks first and thats the queen and it has several lines with other checks and takes like a mate in 3-4
After that i go to captures and there is 2 way 1 with check (rook takes pawn) so i calculate that one with every possible king moves and in that line you can move you king several ways or even take the rook and that lead another lines
After that there is pawn take because its not check and you loseing your bish and your rook so thats might not the best but let see calculate that one too
And i finaly find out there is no way stoping mate from there so i got to a conclusion there is a mate in 3-4-5 if he sacrafice everying
And it turns out there is a best possible outcome what is mate in 13 so i cant even calculated the other other other lines
I might dumb but for me a puzzle is not just throwing a "might" good move and loseing 15 points just because im lazy to calculate the obvious checks and captures befor a single pawn takes with not check loseing half of my board
You have to admit pawn takes is not the most obvious thing with hanging bis and rook and even close to mate threat
You can shortcut it a little by a quick evaluation by noticing the rook is off limits due to the immediate mate threat.
However, as mentioned, many people go for the immediate line that looks most promising, with a quick calculation. Enough to influence the average time to solve.
is dxc3 correct?
Yes
The target time is completely useless as far as your improvement goes. Take the time you need, and make sure you understands the theme and "why" behind the tactic.
First of all, its clear to me, that the first mmove is rxc3. M13? impossible.
or i think
First of all, its clear to me, that the first mmove is rxc3. M13? impossible.
See? Rxc3 is not the move thats why you need more time than 1 min
Yeah, there is Rxc3, then we have to calculate do they have mate earlier than us as they have Rxe8, so a lot of calculation. So, either rating is low or time is less. I have seen many 2000+ puzzzles easier than this.
I hope it isn't one of those trick puzzles, where the solution isn't what would be expected, because that woudn't be a less than a minute puzzle. But if you're playing blitz, you'd have to play it in less than a minute. If you take the N with the pawn, white has RxB+ ....Kh7 but if white takes the R then it's ++ in 2, so what has white got? R a8 hitting the Q. then ...cb+ Kd2 by white, ...b1+Q +, and white plays RxQa2 Qc2+ Ke3 so we have a king hunt and black is the exchange down.
So I won't go for that. Instead, it has to be ...Rxc3+ bc (forced) ....Ba4 threatening ++ Qb2 and I don't think it's working so it's back to pawn takes knight.
I have to say I think this puzzle is incorrect. 2300+ might do it in 53 seconds, otherwise it's only a guess, which isn't the point of puzzles. They should be capable of being worked out exactly in the target time, if there's any doubt whether checkmate will ensue.
Yup but Rxc3 is not correct and the pawn takes is the good one.
Thats why i dont understand why the target time is inder a min
I mean i sit 26 min to calculated this. Ok maybe im not the sharpest tool in the shed but 13 move deep is not under a min
