Yes but I guess that you did not play long time control. As far as I know monarch does relatively better at blitz. part of it is probably because of bugs that are more important at long time control and I saw games when monarch crashed but I believed that part of the problem is monarch's evaluation. As a result even though Monarch had a >much more basic evaluation, the positional score shown by Monarch was much more >stable throughout the game than that of Tiger's. Now normally stability of >score = understanding of position = knowledge. So I can only conclude / confirm >that addition search depth = knowledge.
