I admit that I did not try movei in the previous post but
latest buggy movei show also 0.00 for Rb1

I have not a big book but common sense say to trust search more at longer time
control.

I do not understand the decision of programmer to use the same book for all time
controls.

I have a very small book so I know that movei cannot find better moves at longer
time control but with a big book it is more logical to have moves in the book
that are always played and moves that are played only at short time control.
