Code after basics:
Code:
*-----------------------------------------------------------*
 | 1     27    9     | 45    35    247   | 37    6     8     |
 | 4     678   5     | 1     368   67    | 379   29    23    |
 | 26    2678  3     | 68    9     267   | 4     5     1     |
 |-------------------+-------------------+-------------------|
 | 89    4     1     | 2     68    5     | 39    7     36    |
 | 89    3     7     | 468   168   146   | 5     29    26    |
 | 26    5     26    | 9     7     3     | 8     1     4     |
 |-------------------+-------------------+-------------------|
 | 7     1     4     | 3     2     9     | 6     8     5     |
 | 5     26    26    | 7     4     8     | 1     3     9     |
 | 3     9     8     | 56    156   16    | 2     4     7     |
 *-----------------------------------------------------------*

Two step version:
ANP(67=2)r23c6-r1c6=r1c2-(2=6)r3c1 => -6r3c4
(8=6)r4c5-r5c4=r9c4-(6=1)r9c6-r5c6=1r5c5 => -8r5c5

I originally spotted this as an Almost AIC where either 6r3c4 or 6r9c4 if 6r4c5.
If 6r9c4 then AIC: (8=6)r4c5-r5c4=r9c4-(6=1)r9c6-r5c6=1r5c5 => -8r5c5
If 6r3c4 then Almost Element: 6r3c4-(67=2)r23c6-r1c6=r1c2-(2=6)r3c1 Conflict => -6r3c4
Thus the AIC is valid to complete the puzzle.

One step version:
[6r3c4-(67=2)r23c6-r1c6=r1c2-(2c6)r3c1 Conflict => -6r3c4] = [(8=6)r4c5-r5c4=r9c4-(6=1)r9c6-r5c6=1r5c5 => -8r5c5] => -8r5c5

I couldn't find the Holy Grail, aka one-stepper, so I used an XYZ-Wing, potential DP, M-Wing and BUG+2.
