My solution was more complicated than it needed to be.

That happens with me very frequently, but this was one of the exceptions.

Marty, I saw the making of your solution but I just could not find the full pattern; I must have not completed basics.

In any case, my first move did the trick; I was surprised.

The remote pair (36) is a "single-step."

This puzzle opens the door to two questions that've been nagging me for awhile.

If a Remote Pair only eliminates one of the candidate values, is it really a Remote Pair ... or is it simply Coloring (or some other single-digit pattern)?

Code:
 *--------------------------------------------------------------------*
 | 1      3      56789  | 4      89     789    | 567    68     2      |
 | 2679   278    6789   | 1      5      3789   | 367    368    4      |
 | 57     578    4      | 6      38     2      | 357    9      1      |
 |----------------------+----------------------+----------------------|
 | 35     1      2      | 589    89-6   5689   |*36G    4      7      |
 | 79     6      79     | 3      4      1      | 2      5      8      |
 | 8      4      35     | 7      2      56     | 9      1     *36B    |
 |----------------------+----------------------+----------------------|
 | 25     9      1      | 25    *36B    4      | 8      7     *36G    |
 | 4      258    3568   | 258    7      3568   | 1     *36B    9      |
 | 367    78     3678   | 89     1      3689   | 4      2      5      |
 *--------------------------------------------------------------------*

Similarly, although not true here, if a Skyscraper only eliminates candidates in one box, is it really a Skyscraper ... or is it simply a Sashimi X-Wing? (Actually, it's both, but I love asking this question Very Happy )
