Theoretical question: what position has the largest possible number of different moves that mate in 1? I'm curious what the upper bound is for most possible different moves that are checkmate.
It must be a position where you have a lot of queen. For exemple :
PGN : [FEN "Q7/Q7/Q1K1k3/Q7/Q7/Q7/8/Q4Q2 w - -"]
I count 37 possible mate in one.
The thing is, you have to reach this position.
Edit : Oh. I found this : chess.stackexchange.com/questions/14610/what-is-the-highest-number-of-different-mates-in-1-you-can-have-in-one-legal-p
It seems like a hard position to reach to ! 76 mate in one ! Woaw !
PGN : [FEN "Q7/Q7/Q1K1k3/Q7/Q7/Q7/8/Q4Q2 w - -"]

nice study!
I had a go at creating a more realistic position (without multiple queens etc). There are 18 mates available.

I came up with the Position below, where there are 54 mate in ones. However it is impossible to reach it in an actual game, as Black is either mated or stalemated before entering the position:
[FEN "3QRB2/8/2Q1N3/R1N1kN1R/1Q5Q/4N3/3QR3/K6B w - - 0 1"]
1.Bg7# {54 mates} (1.Bd6#) (1.Nc7#) (1.Neg7#) (1.Ng5#) (1.Nf4#

Most of the other position given here have the same defect: They are unreachable with normal chess rules, as the opponent had to be mated or stalemated in order to achieve the position.
#7 @Lukasel . Please, don't underestimate anything or anyone. It took me about an hour, it is probably not stylish, but...
The position with the 105 mate-in-1 created by legal means.
PS: 50-moves rule - check!

This must be one of the most hilarious things I've seen in a chess forum. :D @Sarg0n
