I like antichess but only play it for fun really (i.e. I am not very good at it!). Never had a situation in which a queen promotion was a good way to go but in this case it worked for me.

You're all far too kind :D
Rook losses, Knight,King quite lost.. bishop would a draw.. So yes promoting to queen was excellent move there... xD
nice job! i've never had a situation where queen promotion in antichess was best :)
