My path for this one.
Look at DP(18)r9c248 => (5)r9c4=(9)r9c8
01: (5)r9c4=(9)r9c8-r56c8=r4c9-(9=2)r4c3-(2=67)r89c3-(67=5)r8c1 => r8c5<>5, some singles

Code: Select all
 *-----------------------------------------------------------*
 | 247   9     8     | 1     3    %245   | 6     247   45    |
 |@24   @25    3     | 7     9     6     | 458  @248-1 1458  |
 | 2467 &2567  1     | 48   %25   %2458  | 9     2347  345   |
 |-------------------+-------------------+-------------------|
 | 1     4    *29    | 89    7    *25    | 358   6     3589  |
 | 3    *26    5     | 489   26    48    | 1    #89    7     |
 | 8    %67   #679   | 3    *56    1     | 45   #49    2     |
 |-------------------+-------------------+-------------------|
 | 9     3     4     | 6     18    7     | 2     5     18    |
 | 5     18    67    | 2     18    9     | 347   34    346   |
 | 267   18    267   | 5     4     3     | 78   #189   1689  |
 *-----------------------------------------------------------*

02: (1=89)r59c8-r6c8=r6c3-(9=2)r4c3-(25)r5c2/r4c6/r6c5=(567)r3c5/r56c2-(567=2)r3c2-r2c12=r2c8 => r2c8<>1, stte

Thanks for the puzzle!
