Especially when you&#8217;re told &#8220;Black to play and win,&#8221; it&#8217;s clear what the winning move has to be.<\/p>\n<p>But in tournament chess, funny things happen. My opponent has just traded queens and then played 22. c4. I think he relaxed after the queen trade, thinking that he could no longer be checkmated. Alas, after 22. &#8230; Ng3+! 23. Rxg3 (of course 23. hg Rh6+ is mate) fg, White has lost the exchange and he <strong>still<\/strong> can&#8217;t stop checkmate. After 24. Nc3 R8f8 White has a choice of being mated on f1 or on h5.<\/p>\n<p>In fairness to my opponent, 22. c4 was not really that much of a blunder, because if he prevents the checkmate with something like 22. g3, he drops a piece because 22. &#8230; Rxd5 forks his knight and bishop. Ouch!<\/p>\n<p>The crosstables for the tournament have now gone up at Bay Area Chess&#8217;s web page (<a href=\"http:\/\/bayareachess.com\/events\/12\/usat.php\" target=\"_blank\">http:\/\/bayareachess.com\/events\/12\/usat.php<\/a>), so you can look up how your favorite team did. As it turned out, Forfeit by Disconnection won by a clear point, with 5\u00c2\u00bd points. There was a four-way tie for second at 4\u00c2\u00bd points between Metropolitan Chess, Norcal House of Chess, ######, and the Hemet Chess Club. Metropolitan Chess took second place on tiebreaks. In fact, it&#8217;s interesting to note that the second through fourth place teams all had better tiebreaks than us, in spite of being a point behind! That&#8217;s because we had so many narrow victories.<\/p>\n<p>Mike Splane, a frequent commenter on this blog, played on the second place team. They had a great comeback after an upset loss in round two knocked them out of contention. Their round-by-round scores were the exact opposite of ours, as they won by huge margins and lost by small margins: 4-0, 1\u00c2\u00bd-2\u00c2\u00bd, 3\u00c2\u00bd-\u00c2\u00bd, 2-2, 3\u00c2\u00bd-\u00c2\u00bd, and 2\u00c2\u00bd-1\u00c2\u00bd.<\/p>\n<p>Amusingly, after 15 years of never being invited to play in the USATW, I was invited to play on two teams this year &#8230; Robin Cunningham&#8217;s team (which finished first) and Mike Splane&#8217;s team (which finished second)! I guess there was no way for me to go wrong, except perhaps by declining both.<\/p>\n<p>Other random tidbits&#8230;<\/p>\n<p>There were 4o teams overall.<\/p>\n<p>Only one person went 6-0: Art Zhao, who played board four for the fourth-place team, ######.\u00c2\u00a0 However, I think that Steven Gaffagan and I deserve some kind of recognition for scoring a joint 6-0 on our fourth board!<\/p>\n<p>Not only that, our team prevented two other people from going 6-0, and they were both hugely important games. In round five Julian Chan pulled out a remarkable draw save against Ron Cusi, which was the only blemish on Cusi&#8217;s otherwise perfect 5\u00c2\u00bd-\u00c2\u00bd record. And in round six Todd Rumph saved an exchange-down ending against John Langreck, who had gone into the round with a 5-0 record.<\/p>\n<p>And meanwhile, Todd Rumph reports that the following teams won the other three sections:<\/p>\n<p><strong>East<\/strong> (always the biggest region &#8212; this year they had 294 teams!): Forking with Tebow&#8217;s Knights, 5\u00c2\u00bd-\u00c2\u00bd.<\/p>\n<p><strong>North<\/strong> (39 teams): Chess X-Men, 5-0.<\/p>\n<p><strong>South<\/strong> (40 teams): Yo Doy Clase, 4\u00c2\u00bd-\u00c2\u00bd.<\/p>\n<p>All four regions had a clear winner &#8212; there were no tiebreaks required.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I know my faithful readers want to hear more about my team&#8217;s victory at the US Amateur Team West this weekend.
