I think, Yace is not so good at mates, where the position already looks won,
because it limits its extension here (or better, doesn't do most extensions at
all). Also, I think it is not important for practical playing strength, because
with a score of +9.x chess programs will usually win (studies might be an
exception).

Another example, where no large advantage can be found at shallow depth:

[D] 6r1/2rp1kpp/2qQp3/p3Pp1P/1pP2P2/1P2KP2/P5R1/6R1 w - -
