Detail 1. Taking Scandinavia from Germany

Variation: If you are not facing UK as an opponent (rare for competitive 3v3 games) you may want to change some minor things:

• Leipzig: move 2 Infantry to take Prague (Czech Republic)
• Berlin: buy 5 Infantry and 3 Militia; use the three Militia to wall Berlin; the rest of Infantries to take cities as usual, diminishing number for Prague, since there are going to be 2 Infantries coming from Leipzig
• Frankfurt: Use 4 Infantries to take Brussels (Belgium), instead of Switzerland
• Cologne: buy 3 Militia (now possible because of less expenses in Berlin) and take Amsterdam (Netherlands)
