Gold to Move and Goal-in-Long

This is a collection of the longest wins discovered from actual games. These are the conditions:
- The root must have occurred in the game
- This game must have been serious. Games with collaboration to reach the win's root or special games such as EEE games make the win ineligible. I may use my discretion here.
- The win must be fully proven using bot analysis
- No quicker wins may be known from the same position. Alternative solutions of equal length are fine. Being unable to prove that no quicker wins exist is fine, but as soon as one is found the win is invalidated.
- The win must be at least six moves long. This is subject to change if the list grows.
The win doesn't need to have been played, nor must the win actually be gold to move 
I reserve the right to modify these conditions at will, but I will try not to.
The list:

I actually have that position recorded in a file of my own. Here are my notes about it.

Here is a position that I also have recorded in my own notes. I don't know where I got this position, but perhaps an automated search through the archives can find the game (if any) that it originated from.
Code:
Turn = 55s
+--------+
8|........|
7|.D.rc.r.|
6|rmd..*r.|
5|r......r|
4|R.Hr.eHd|
3|..*.ERrR|
2|..RR.hC.|
1|....D...|

There might well be a faster win, but if Silver flips with f2s g2w f2w f1n, the only move for Gold that does not lose in 3 is e1e e2s f1e g1n. Silver can therefore win in 7 by repeatedly flipping until the the repetition rule stops Gold from being able to play this defense.
I have several other deep goals from my notes, but not the games associated with them. All of them are real-game-derived, but I suspect that several of them are from a slight variation from the game that produced them.
There are also probably a few wins-in-6 or deeper findable by searching through old chat archives (but that I don't have a record of).

sharp/lightvector was able to confirm 36g in this game as a win in 6. Alas, I was unable to prove that before actually playing it.

hanzack found this goal in 6 in one of his own games. I don't know if it's ever been confirmed with bot analysis, but it obviously deserves a mention here:
Puzzle
Original game (move 30s)

In my postal vs. zero 23g Ef7e Eg7w rg8s pass (played move just without the last step) would have been goal in 6. Found by sharp, see chat 20th March 2015 12:36:25 UTC.
