A very strong puzzle

Definitely constructed, but nice for all of that.  Lots of variants on the open-field mate with a supported queen to look at, with the two squares the queen can't cover blocked off by the knight or by black pawns.  I didn't quite get this the "right" way, but close -- after trying and failing for a while to work out a mate on e4 or various other dead ends, I played the first two moves just to see if they were right.  Knowing that they were, getting back on the bishop's diagonal while blocking the b file escape path jumped out as promising, and of course it turned out unstoppable.

EASY

huh

good one

I was unable to find out move 3 by myself...

kinda hard in the 3rd move but NICE !!!

got first two moves but didnt get the third one

hard!

ultimate:)

good stuff

move 3 is a bitch

Great puzzle.  Of course, I would never do this in a real game when N x Q is so easily, simply and overwhelmingly winning.  But still, puzzles like this are good for the development of ability to see opportunities.

No way to check on all moves to mate in 4,hit help on move 3,then mated with Q.Nice puzzle.Thanks Chess.Com,good day chess heads!!!!

Move 3 is brilliant. After 3.Qb1, there's nothing black can do to prevent Mate in 1.

Third move was really difficult.

Cool puzzle!
