I don't see that it makes any difference at all.
A. qxf4, pxq, rc7, qxr, ne6, king moves, take queen, you come out with an extra knight, easy win
B. rc7, qxr, ne6, king moves, nxr, king moves, take queen, he takes your queen, you have an extra knight, easy win
C. ne6 straight off is impossible due to the knight being pinned to the king.
Can't see how Qxf4 than Rc7+ is better as I'd lose my queen & wouldn't be able to take his. What am I missing here? (I'm white)
Thanks in advance!
