optimal play: 17...Rg7!
<morphynoman2: 22... Ng4!!> Agree!
<admeyer: double !! well deserved for setting up a mating net with minor pieces.> Yep, double !! well deserved, although it's not really a mating net but rather a decisive material advantage that wins, since after 24...Nc2+ the continuation might go 25.Ke2 Nd4+ 26.Kf1 Nxb3 27.Rxc5 Nxc5
Also if 23.fxg4? then 23...Bb7+! also wins.
<aragorn69: This week's Saturday puzzle ??> I think it's worthy of a puzzle, if not Saturday then maybe a Thursday or possibly Friday?
This game is from the 23rd Chess Olympiad held in Buenos Aires (Argentina) 1978, played on 26th October, 2nd round, board 3, between Yugoslavia (white) and Australia (black).
Yugoslavia won the round 2½-1½ and finished 15th out of 65 teams; Australia finished 30th.
The 18 year old Ian Rogers, at his first Olympiad, finished with a score of 6½/11 [+6/=1/-4] while GM Velimirovic had a poor Olympiad with only 1/5 [+0/=2/-3].
