It should not be difficult to find many such agreements, same for every pair of great master and very strong engine.
I randomly chose one short Capa white win and ran a
blundercheck with threshold zero over his moves. Only moves where Stockfish 3 disagrees at depth 20, receive engine alternatives:
[Event "Moscow"]
[Site "Moscow"]
[Date "1925.??.??"]
[Round "?"]
[White "Capablanca, Jose Raul"]
[Black "Marshall, Frank James"]
[Result "1-0"]
[ECO "A14"]
[PlyCount "57"]

Except for the opening, we find almost "100% Stockfish moves"

in the rest of the game! That is much more than I expected. SF only would like to play the swap on e5 one move earlier. All at depth 20.
