The question was "How to take advantage of White´s uncoordinated pieces?".
1...Qe1!
2. Nd3 (or 2. Nf3 ; 2. Nc4 )
2...Qe6!
...and in the best case White would lose a piece.
Only this solution is the right one. There are few more interesting continuations, but only this leads to winning advantage for Black.
