Poland and Spain concern me on that map. Poland's neighbours have four centres each, and three-centre poland is sandwiched between the two, butting it at an unfair advantage at my first glance. Three centre Spain has a corner position, but that Fleet in Gibraltar limits its ability to expand greatly, as it will porbably only be possible to get one of the local neutrals.
