The Russians have the problem of supply depot, in 1757 after not taking Könisberg, they had to come back on their borders, when Königsberg was taken they were too long to take Kolberg or Küstrin for a new base of opérations (Kolberg fall in 1761 but too late as Elysabeth died the same year).
The players will try with hindsight to avoid this but perhaps there will be events or so...moreover playtesting is there just for that, to have balance and historical result.
