Wana be friends?
Sure
In #6, you annotated 5...a1=Q a blunder, however you did take note that it was forced, so it can't be a blunder. Also it can't be a puzzle because you could promote to any piece, not just a queen, and white would still checkmate.
here's the position:
#2 has no solution - considering that the bishop on f5 is illegal if white plays top to bottom and the smothered mate fails if he plays bottom to top.
#3 has several solutions though not in 1 move.
That doesn't make any sense at all lol #2 absolutely works, at least with black to move, which it is. What do you mean by "if white plays top to bottom and the smothered mate fails if he plays bottom to top" I don't understand what you're talking about with all this top to bottom and bottom to top stuff
#3 only has one solution, Nd3#. And by the way, I checked all the positions with the engine. They are all correct.
Puzzle positions need to be legal (achievable when playing a legal chess game) and the one in #2 is not. Unless you play the diagram assuming that white's 16 units started from the bottom but then there is no smothered mate solution because white will capture the black queen with his pawn and promote; Pa7xQb8=Q.
You are right about #3. The diagram states "1-0" which in "puzzle vocabulary" means "white wins" in any number of moves However I apparently missed the text after the diagram which presumably instructs us to mate in 1. Of course, there is only one mate in 1 move. The real issue is that chess.com does not conform to standard notation for chess problems. If it did the diagram caption would read: "#1" (mate in 1) rather than "1-0" (white wins).
Aha! I wasn't thinking about the fact that the bishop couldn't have ever left f1 in a legal game. Lol thanks for pointing that out. Also "1-0" doesn't have to do with "puzzle vocabulary" as it's used in chess games to indicate the result of the game (for example in scoresheets after a tournament game). It is not limited to puzzles.
Yeah I was gonna mention that but I forgot. Sorry
It's ok
