Movei say +0.53 for white at depth 9 and +0.54 at depth 10.

It is surprising that yace says close to 0.00 evaluation because yace only
material score is +0.81

I understand that the fact that white has 2 pawns at the c file is a positional
disadvantage but still I expect yace to have similiar score to movei.

I believe that it is a mistake to evaluate queen as more than 2 rooks but it
seems that the information that yace evaluates queen as 10.01 and rook as 5 is
misleading and the positional bonus for rooks is usually bigger than the
positional adavantage for the queen.
