Gen fic, post "Operation: Annihilate!"

[pharrezychica.livejournal.com]

Hello!
I seem to have misplaced the link to yet another fic...

I'm pretty sure I read it on fanfiction.net .
One shot, takes place right after the TOS episode "Operation: Annihilate!".
It featured Spock helping Kirk's nephew Peter to overcome the trauma through a game of chess, teaching him about life being unfair yet helping him to cope with everything that happened.
McCoy and Kirk were watcing and commenting ...
It's one of my favorites post-Deneva fics.

Does it ring any bells?
Any help would be greatly appreciated!
