The rarest move in chess ?
Sort:
Those are pretty rare.

Even more rare would be 0-0#

PurplePuppy, put the King on a6, and keep everything you said and it's also checkmate!

Incorrect. Then it would be Bxd5#. The other two bishops are required to add the c and the 6.
There will be several other positions (most with more pieces) but three white-squared bishops are required. (So two promotions to white-squared bishops must have occured.)
It's just a notation thing, so I don't think it should be considered rare.
In the old days it would be c6d5

Surely, it is the notation that describes the move? If the notation is different, then the move is different also. Of course, this wouldn't work if we were still on the 'old-days' notation system.

No, there are different notation systems, so constructing a move explicitly because it is rare in one specific notation system seems artificial.
It may be artificial, but it's all I got, and I'm sticking to it! 
Ok, you're probably right... but do I get a prize for 'the rarest notation in chess, under the short-algebraic system'?

After reading the wonderful Tim Krabbe (wish I could put the appropriate accent in, but I don't have enough time to work out quite how at the moment; sorry, Tim!) article, I'd like to present an interesting position I found whilst analysing an endgame from a game I was playing some months back.

A smothered mate in the middle of the board also has to be exceedingly rare.

Here's the double-discovered check, and for checkmate to boot:
This position is impossible to achieve I think, if I am wrong then please show me the moves leading up to this position? =]
It is possible -- the King entered via b4 before the Bishop arrived on e1 to deliver check. White's only defense was b2-b4 to block the check at which point we've arrived at the initial position in my diagram.

What is a "rare" move? Seems like we need a definition. Nytik found a very rare move for simplified algebraic, which makes sense for this site. If that seems artificial, then just what is a "rare" move? Do we need to set up a whole position to define rare. That seems silly since, not playing an obvious mate in 1 is no doubt quite rare. Any number of absurd positions involve "rare" moves.
The notation makes a huge difference of course. The simplified algebraic move: Ka1# is not particularly rare... But in longer form either Kb1-Ka1# or Ka2-Ka1# are very rare: they're impossible.
We could also try to find a definition for the word "move" as in Nytiks clever idea one could say that the move itself is simply bishop from c6 takes on d5.
And the facts that there are two other bishops on board and that the bishop move checkmates the opponents king describe the position, not the move.
So maybe Bxd5 and Bc6xd5 or Bxd5# are the exact same moves, only notatative description of them is different.
Well, im just stirring the water a bit.

In actual tournament play it has to be...
You must be either handing a game to your mate because you have qualified for the next event and he needs a win to get there also or you're a complete plank...
I think we are assuming short-algebraic notation! i.e. the notation used on this site. So Bc6xd5# is exceptionally rare.
Very resourceful Nytik. I like it! Seems like a rare move, too!
