It follows from Mohex's result for 49 that C9 now wins for White. (Peter\: See second variation on next move.)

E4 would probably have been better than F4. (Peter\: See next variation on this move)]

It takes longer to check, but it also follows from Mohex's result for 49 that this keeps White's win.]

(As mentioned, White has a win no matter what Black played here.)

I thought this was a good move at the time, and in terms of connecting D7 to the 13 edge, I still think it's a good move.]
