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.

It may be interesting to compare Crafty with fruit's evaluation to Fruit to see
if Fruit really has big advantage relative to Crafty in search rules or I simply
overestimated the value of Crafty's evaluation.
