KQNKQ is generally an easy draw with some exceptional cases. Qxf4 reaches such
an ending with 2 extra pawns to boot, so I can't fault Qxf4. I can't see
anything particularly wrong with the choice. Why do you think this is a blunder?
Bear in mind that engines might return a large negative score in endings that
are easy draws.
