Bob would probably say not to think about it since it's qsearch and therefore
very vague anyway. :)

I don't have much experience when it comes to evaluate such positions with my
engine, but are you sure it's a good idea to evaluate two connected pawns on the
7th row at least one rook? Are there more positions where this is right than
wrong?

I can imagine that chances that this is good are rather high when there are no
queens around anymore. But with queens still on the board I can imagine lots of
checks which capture one pawn and give check at the same time, which quickly
nullifies the advantage again.

Sheesh, I guess Bob is right and we shouldn't think about it too much. :)
