"Knight rebus"-Decipher an encoded chess position Here is a knight rebus. Each letter represents a different type of piece.
Uppercase letters are one color and lowercase letters are the other.
Determine the position. If possible, also determine the previous moves.

n and N are kings and h is pawn. What is the rest?
Assume the board is in it's usual position (the bottom row is the first row) then this is the solution:

[FEN "1B6/8/1k6/R7/1n6/2K5/r6p/q1r1n3 - - - 0 1"]


and Black's last move was b2xc1R++.

I could write an explanation here about I came to this result, but it would essentially be copying @Maxwell's answer. I didn't use it, though.
