Sometimes you don't have to complete all the basic moves to find a solution

At this stage, r4c7 = 1 to solve
Code:

+--------------+----------+------------------+
| 56  2    1   | 9  8 3   |  4   7      56   |
| 4   35   358 | 56 7 1   |  9   2      356  |
| 356 9    357 | 56 4 25  |  8   1356   1356 |
+--------------+----------+------------------+
| 158 14-5 6   | 2  3 9   | a15  14-58  7    |
| 9   35   358 | 4  1 7   |  2  b568   c568  |
| 7   14   2   | 8  5 6   |  3   14     9    |
+--------------+----------+------------------+
| 15  7    4   | 3  2 58  |  6   9      158  |
| 135 6    35  | 7  9 458 |  15  13458  2    |
| 235 8    9   | 1  6 45  |  7   345    345  |

From Gianni's grid, r2c2=5 to solve

If r2c2=3, then you would get a <56> pair in box 1 and box 3 which would then leave no room for a <5> in row 7

I used the X-Wing of 5's in rows 1 and 7 (see Gianni's grid) and that opened up a couple of 356 XY-Wings which solves it.

Also if r2c2=3 you would get a <56> pair in box 1,2 and 3 which looks to me as a type of Unique Rectangle. Or is it something else?
