Hm, unexpected result for sure! Don't know if it was because of his 4-3W-1-2/ 4-1-3W-2 formation or just "bad luck". You could try to fight "fire with fire" in the return, or use any formation with a four-man line defense. What is the "counterformation" for a 4-3W-1-2: The 3N-1-4-2, 4-4-2 (Wide diamond) or 4-5-1V?
