Tough Sudoku for 4/October/2017

Basics to UP = 34.
1. (9)d2 = e23 - (9=4)e8 - df9 = HP(49)gi9 => -9i2 ; UP = 81

I overlooked the more obvious
(4=9)g9 - g3 = e3 - (9=4)e8 => -4df9

1. Unique possibilities to 34.
2. Whether e8=4=g9,i9=9;OR e8=9=d2;i2=1.UP81.

Hi rwm. In your second post, after 9 @ g9, can't i3 also be 9, not only e3?

Best regards, Alfred.

Basics to 34
1. M-wing (9=4)e8-df9=(4-9)g9=(9)g3 =>-9e3; basics to 81
Another path with an almost X-wing (9)R48:
1. [XW(9)e4*=f4-f8=e8]==(9)d4-f4=(9-5)f8=(5-469)dfg9=(9)g3 =>-9e3; basics to 81

Never heard of this plant. Kate for the info.
