You are in the South Atlantic in WWII. You have 12 battleship groups of varying strengths.

You have to find and destroy the Bismark in a grid about 1 units square. It took me three minutes. Lucky maybe, but 1m not going back for another go - i've got too much sleeping to do. This comes, incidentally, from Argus Press, who publish all sorts of really naff computer magazines; but even they should know better than this.
