No advanced steps needed.
Still took me longer than today's vh
Code:

+-----------+-----------+-----------+
|  .  .  8  |  1  .  6  |  .  .  7  |
|  .  6  4  |  .  3  .  |  .  2  .  |
|  .  .  .  |  .  .  .  |  5  .  .  |
+-----------+-----------+-----------+
|  .  .  .  |  .  .  .  |  4  .  6  |
|  .  4  .  |  .  2  .  |  .  3  .  |
|  1  .  7  |  .  .  .  |  .  .  .  |
+-----------+-----------+-----------+
|  .  .  3  |  .  .  .  |  .  .  .  |
|  .  8  .  |  .  5  .  |  2  1  .  |
|  5  .  .  |  3  .  4  |  7  .  .  |
+-----------+-----------+-----------+


play online

Hint:
I believe this puzzle is easier to do on paper than online. There are quite a few hidden pair/naked quad, quint etc.

I saw an x-wing (7) in rows 5 and 8 before even finished with basics, which would solve r2c1=7, but since this is a "hard", decided not to use it. The turning point for me was the hidden pair 46 in row 6, which led to hidden single 7 / or naked quad 1469 in col 5)

three tries before finally seeing a hidden pair {4,6} in row 6 box 5. which opened up a hidden single 7.

I started out with locked candidates in three boxes, which opened up a 79 pair in c1, followed by the 7 hidden single. Then three more pairs and a 3589 quad in r6.
