create a database with the game nikolic vs fischer up to move 19...Bg4, then
save it. When you run engine vs engine, put that database on the opening book of
the engine match, the the engines will start playing from move twenty.

Another option is to open the nikolic fischer game, play the game up move
19...Bg4, then go to tools, then click training, then click theme blitz,  the
position will appear in a small dialog box, press ok, the go to the engine match
and the game will start from that position.
