grabapawnski: Move 6 given for black is wrong.
6) ... c5 was never played, the move D. Chrichton played when demolishing my uncle was much better 6) ... f5. This threatens to win the N with h6, as it now has no escape squares. That is why uncle Bob played 7) h3. His idea was to meet 7) ... h6 with 8) hxg4 subtly defending the N. Chrichton's 7) ... Bg3+ was a slight oversight.
To make matters worse, this was a correspondence game, played between Robert A. MacBrayne and D. Chrichton in the Scottish Correspondence Chess Assosiation Swiss Round 3 during 1980. The game was published in their News Buletin Number 5 in May 1981 page 11. I have it in front of me now.
Bob MacBrayne was a life-long chess player and a little better at Corresp. than OTB, but never got an IM norm at either. That must be a different MacBrayne.
I remember playing him when I was a child c1958, he let me win of course. He was a tourney player & I was about 5 years old. After the game I wouldn't accept the improvements he suggested on the grounds that I had just won so must be better than he was!
Apart from having a claim to what must be one of the quickest losses by checkmate in correspondence history (above), he aslo won a game after his death c1990. (Corresp. adjudicated by Roddy McKay IM)
