I got it entirely, but honestly despite having 2600 - 2800 as tactic rating I didn't know it would have ended in a stalemate. I realized it only after the third move.
Having said this, almost all moves are forced, so although it is difficult as puzzle, find the solution it isn't.
The first couple of moves are intuitive, but people fail on the last move - which is the point of the puzzle. Due to Chess.com's tactics rating system, they get a score of something like ~70-80% and get rating while the tactic loses it. If one would have to deduce the solution from the beginning or had to solve it fully to get a positive score (such as on Chesstempo), its rating would most like rise for hundreds of rating points.
How does that skew any ratings? The problem is rated as it should be. Also, I just looked at the problem... How the hell does anybody get that wrong??? There are two legal moves, one is clearly lost and one is clearly drawn. How is anybody getting that wrong?
I explained it already. Come on, it has a 11% pass rate. On Chesstempo, all problems with low pass rate are extremely high rated, because there partial solutions don't count.
