JC, starting from the same place, I went a different direction | Code: |

(6=8)r8c9-(8)r8c5=(8)r3c5-(8=5)r1c6-(5)r1c78=(5)r3c9 => r3c9<>6 |

| My first solution was pretty messy, my second one was cleaner. R8c9=8 proves r3c8=6; r3c9, r89c8<>6. |

The only interest I found in the solution I posted above lies in the fact that it is a rewriting exercise of a solution in 2 steps : Kite(8R1C5) => -8r8c7; MWing(36) => -6r8c9; stte
This was successively done as :
1. Kite(8R1C5)-8r8c7=MWing[(6=3)r8c7-3r2c7=(3-6)r3c8=6r3c9 => -6r8c9]; stte
2. Almost MWing : 8r8c7=MWing[(6=3)r8c7-3r2c7=(3-6)r3c8=6r3c9 => -6r8c9 or +8r8c9] => +8r8c79 => -8r8c5.r9c7; stte
3. Or (68=3)r8c79-3r2c7=(3-6)r3c8=6r3c9-(6=8)r8c9 => -8r8c5.r9c7; stte
The final solution is thus based on 4 SIS instead of 5 while remaining equivalent to the simpler initial one.
On the other hand, a solution proving +6r3c8 still need "Pointing : +8r8c79 => -8r8c5" before stte.
