Poor annotations, ignoring 41...c6?? which gives up f-pawn for nothing. It also lack explanations why Black 32. and 40. moves were bad, without offering reasonable alternatives.
Speaking on opening - Black had interesting alternative 16...Qh4 (instead of 16...Rfe8) with idea to prevent castling and push pawn on e3. Black would have very powerful initiative for 2 pawns and I would not like to defend such a position for White.
Pacifique line 16... Qh4, analyzed with houdini 2. The final position evaluated as a draw.
1) Too long line to be forced.
2) If it`s draw, it means that knowledgeable Black player can draw easily.
Of course is not a forced line, but I tried to get at least 28 depth every 2 or 3 moves, this is just the top choices of houdini. Just to show a reasonable follow up.
Close but no cigar!
