Dutch is a turtle civ cause of its infrastructure based economy and lack of musketeers. In a Russia vs Dutch match up, it is the russian player who should rush, particularly with Cossack to which dutch has no effective counters in age 2. The fact that you got rushed by dutch and you were turtling in base with Russia using blockhouses and strelets tells me that this game was very low ELO. Not even the Dutch AI tries to rush cause e knows he will lose, he will always go FF.
