fredthebear: 11.0-0 or 12.exNd5 and White is better.
Frankly, the blunder 12.Qe2? looks like a computer consultation move where White was off the mark by one ply (meaning 12.exNd5 d6 13.Qe2+ was intended).
FYI: Americans had PCs back then (no laptops in 1989, no cell phones [yes some had satellite phones], and email was not en vogue), so a correspondence player might be getting some software assistance, perhaps not so reliable.
The final position is somewhat playable down a piece, as the Black king is exposed. It's probably not worth the postage though, especially when a guy could be watching the inaugural season of the dumb spit Simpsons, Night Court, Family Matters, Mr. Belvedere, Who's the Boss? Charles in Charge, The Gong Show, Doogie Howser M.D., Dallas, or Dynasty back then. (I would have been watching Columbo, Cheers, Seinfeld, Moonlighting, The Young Riders, or the Atlanta Braves...if I wasn't working a night shift.) Of course, a sheepish White would be further embarrassed to move his queen again. Best to be done with this game.
