user8751: This is the first of a series of challenges I'll be posting regularly. In this case it is just a simple mate in one. This is the position:
 [Title "White to mate in one"]
 [FEN "1Bb3BN/R2Pk1pr/1Q5B/4q2R/2bN/4Q1BK/1p/1bq1R1rb w - - 0 1"]

White plays and gives mate. It seems very easy but there are a lot of pieces in the board. I'll be increasing or reducing the level of the challenges based on the answers.

user8796: Moving

 D7 to D8 

ending up with 3 Queens              

user12873: Nice puzzle, this took me a few minutes. 

The answer is 1.Qa3#.


user7297: It seems that

 Qa3

is mate in one. It is indeed harder than it looks at first sight, because there are so many pins.
