Hey guys, got a game tonight against a side a Little lower in quality than myself, he plays a 4-1-2-1-2(narrow diamond), i usually play 4-3-1-2 but my amc is out and i hav no cover, well i then usually play 4-4-2, but i noticed that on the table of counter formation his formation counters a 4-4-2, it says that i can counter his wiv a 3(n)-5-2(v), not really sure wat it means by v shape, is it a dmc, mc,mc, aml, amr, well if so i dont hav a amr, does it matter much if u play a mr, in that position, or has any1 got any other suggestions of how i go about winnin the match, many thankx guys.
