1...Rxg4 a 2.Sxc7# A (c4?, Qd3?)
1...Rxc6 b 2.c4# B (Qd3?, Sxc7?)
1...bxc6 c 2.Qd3# C (Sxc7?, c4?)

1.Se4! th. 2.Qc4#
1...Rxg4 a 2.c4# B (Qd3?, Sxc7?)
1...Rxc6 b 2.Qd3# C (Sxc7?, c4?)
1...bxc6 c 2.Sxc7# A (c4?, Qd3?)

Lacny cycle where all defences seem to allow 3 mates by blocking c6 - however then there are dual avoidance effects in all variations.

#2 (10+9)
