Counter formation saying : 3N-2(DML/DMR)-3N-2 OR 4-3N-3

BUT here is my short experience about countering with 433 against 451V: BAD I don't know who was the smart guy putting this 433 into counter variation but i lost all the time with that! although the good old donut formation (3n/dms/3mc/2st) is performing pretty well against V

imho!
