RonB52734: Going through my notes here, I see that Bruce Leverett's annotation of the game hasn't yet been published in our club newsletter, thanks to a rare abundance of other articles. So I'll tease you with a few items and later I'll link to the online newsletter.20. Na4 Ne8 thus generating a new saying: If a knight on the rim is good enough for him...
31...a5?
33.hxg7 (is this technically the Queen sac?)
33...Nxg7? (isn't 33...Rfe8 much better?)
34...Qxb6 (there goes the White Queen, but here comes a White mate-in-7 that might have been.
35.Nxe7+ <and now 35...Kh8 36.N5g6+ hxg6 37.Rxg6 Qxb3+ 38.axb3 Kh7 39.Rh1+ Bh3 40.Rxh3+ Nh5 41.Rxh5#>
The contestants play along with
35... Kh8
36.N5g6+ hxg6
and now, maybe the position would make a good puzzle. I'll let better players than myself speculate what day of the week it would deserve.
I'll have more to say, including Ulvestad's own explanation, after the next issue of the Pittsburgh Chess Club newsletter comes out.
This game probably decided the 1946 US Open. I believe Ulvestad was in the lead going into it. Steiner ultimately took home the title.
