Ne4 Qc7 {and now Option D is correct after} 20. h4 $1 {This excellent move is correct as White recognises he needs another attacker before Black can consolidate.} ({Option A -} 20.

Ng5 {In principle this might seem like a good idea but after} Nf6 {Black has added a defender and now controls the important d5 square. The chances are about equal.}) ({Option C -} 20. d5 {The weakest move. Whilst this plan might achieve the objective of eliminating White's 'weak' d-pawn it gives up control of the e5 square and there is also a tactic to follow. After} Nde5 21. Qg3 cxd5 {and if now} 22.
