STUPID CHESS PROBLEM

also, does anyone have bigger number of solved puzzles, than I ?

I did, more than 15,000. When I don`t like the problem, or the last part of it, I just go the next one, problem solved. There are many exactly like the one mentioned on #11 - and even worse - with plenty of (confirmed by engine) mates in less moves then the "correct answer", and even mates where the "correct answer" is not a mate, just a big advantage. Hard to understand how a super-engine makes lots of this type of mistake. The higher the rating of the problem, the worse it gets. In the upper levels there are 2300 rated problems where it`s easy to get the interesting and instructive part, than I make a random move to see if I get lucky on the part of the problem that should not exist, and usually fail it.
