To Lorfa: Some of your lines seem too long. Rxf7 Qd8 Qxg7# Rxf7 h6 Qxg7# The longest lasting defence seems to be Rxf7 g6 combined with a later Q sack on d8.

It seems to be mate in 5.
Qe6 seems irresistible. Threatens Rxf7 followed by Rc8 mating or winning queen and indirectly defends f2

The longest lasting defence seems to be Rxf7 g6 combined with a later Q sack on d8.
