from P.O.'s candidate grid...

(6=5)r7c5 - (5=1)r9c6 - (1)r6c6 = (1-6)r6c3 = (6)r8c3; r8c46 and r7c1 <> 6

leads to

(3=5)r8c6 - (5=6)r7c5 - (6=3); r6c6 <> 3

then there is one naked pair to find, then its singles.

thank you for your answers, my solution:

Code: Select all: 2r6c39 => r3c1 <> 4 r6c3=2 - r3n2{c3 c1} r6c9=2 - 145r789c9 - r2n4{c9 c2} ste.
