Is 4-1-4-1 that good against 4-3-3 ?

[Ṃř Sǚffệŕḝṝ]

yes , the counter formation of 4-3N-3 is 4-1-4-1 or 4-5-1 flat as i think

you have 4 DC against 3ST , 2MC and DMC against 3MC and (ML-MR ) .. they will make the difference

Also, his attacks are concentrated in the center section of my defense. But there is exactly my weak spot since there's no defender there.

--DL--DC-(weak)-DC--DR--

so put blue arrow on DMC (( --DL--DC--here the DMC defend and attack as MC -- DC--DR ))
ML-MR also red arrow .. they i'll take two places ..

or if you want replace DMC with AMC and give him red arrow ...

--DL--DC- -DC--DR--

MR--MC--MC--ML

AMC

ST
Cuz he don't have DMC to block him ...
