Daily chess puzzle: Check Mate #196

Aulicki v Formanek, Czechoslovakia 1954

1 Bf6! is a nice first move. It clears the h file, threatening 2 Qh7 mate, so Black’s tries are limited.  My engine gives it as by far the best, but also says that the simple 1 Rg3 is winning, too.

1…Nf6 2 Qg8 mate

So instead 1…Rf6 (1…Qf6 2 Qh7 mate) 2 Qh8+ Kf7[] 3 Rh7+ Ng7[] 4 Rg7 mate.
