Movei needs less than a minute to fail high on Rxf1 but the score for Qxf1
before the fail high alos showed advantage for white.

It had a big fail low on Qxf1 but even after the fail low the score was about
one pawn advantage for white.

After I give it Qxf1 it has a fail high on Rf8 at depth 9 but the score is also
good for white inspite of the fail high and the score at depthes 10 and 11 does
not continue to improve for black so I am not sure that movei will not change
it's mind to Qxf1 if I give it a longer search.
