It was only after that I thought to look at it again with Nimzo. But by then all I had left with just a clean pgn file. I even tried re-booting thinking maybe it had a stored evaluation. It could have been caused by pondering. I watched it from the start and it was thinking about the winning the pawn while thinking of the two piece exchanges. While MCP8 was thinking of it's reply to Qxc2 Nimzo was already stating the next 5 moves and that it was lost, all this while MCP8 was still scoring = but it had the first three moves and would see the 4th and 5th as it got there. Fortunately there was nothing riding on this game. Thanks.
