I think your engine is making a colossal mistake.  In fact, I think that black
is ahead.  After threatening on the h file with the rook, the pawn at e6 will be
taken by the black queen.  White will play a bit of "around and around the
mulberry bush" but there won't be any "pop goes the weasel."

In the very near term, white will be down two full pawns and hoping for some
sort of compensation that is not going to happen.

Maybe a real chess expert can look at it.  But if I walked up to this board and
someone said, "Would you rather be white or black?" I would choose black.
