TimeMoreWhenLosing and TimeMoreWhenWinning were checked for these game.

TimeImitateOpponent: Idea is not to fall too behind on time
TimeMoreWhenLosing: Play slower when eval score gets worse
TimeMoreWhenWinning: play slower when eval score gets better

TimeImitateOpponent and TimeMoreWhenLosing combined have been tested, and did well. Though TimeMoreWhenLosing code has changed slightly with new conditions added in latest IvanHoe. TimeMoreWhenLosing and TimeMoreWhenWinning only makes sense in very long time control games in my opinion. Used in short/blitz games, IvanHoe might get into time trouble.

No. The first one is Ahmed's compile and the other one is KLO's compile, based on the same source. I think Ahmed added some eval changes on his compile.
