Even Odd Chessdoku 2013 - 2

Today we have another Chessdoku, but this time it also doubles up for the League's puzzle. The week has started off interestingly with some great puzzles Arrow Sudoku by Fred, Search 9 by Prasanna and a Renban Sudoku by Bastien.

I hope the chessdoku lives up to the level set up by the previous authors for the week. This is not a difficult puzzle but then it does require a wee little bit of thinking.

Fill the grid such that every row, column and 3x3 box contains the digits 1 to 6, a Chess King(K), Queen(Q) and Knight(N). Additionally, a King cannot attack another King, a Queen cannot attack another Queen and a Knight cannot attach another Knight. Each piece following their moves as in chess. Grey cells can contain only even digits and the orange cells can contain only odd digits.
