Michael,

Normally I like to use the default settings because it shows users what they
will get "out of the box" without having to make any modifications. I like to
leave it to the "enthusiasts" to show what their own personalities are capable
of.

However, in this case, you are definitely correct. On the same P3-733, CM_SKR
finds 19...Bf5 with a score for Black in only two seconds:
