RomiFischer vs RomiKarpov for some lite fun

[Michael Sherwin]

I created two instances of RomiChess. One with merge Fischer.pgn and the other with merge Karpov.pgn. The time control is 5+1 and the number of games will be 24. It will not be accurate as Romi will play once the RL is done in each game. Learning is on for both engines. It is just for entertainment, nothing more. I'll post each game as it finishes.
