Prussian Opening, The Barbarossa
This opening, named by Richard Sharp, is Germany's most aggressive opening towards the east, sending Mun-Sil and Ber-Pru. Note that both Holland and Belgium are ignored, virtually asking for an English convoy to Holland. In addition to the Barbarossa Proper (F Kie-BAL), there are two variations: the Danish variant (F Kie-Den) and the Dutch variant (F Kie-Hol).
