1 Queens Chess Club Championship 2017 October 6th to November 17th 2017 Welcome to the 2017 Queens Chess Club Championship!! The time control is G/120, d5. A delay clock is preferred. Please bring sets and clocks. Our normal seating arrangement is to face all clocks toward the center aisle. The TD needs to be able to see the clock. We no longer enforce Rule 14H, which allows a player in time pressure in a game without time delay to request a delay clock, claiming no losing chances. We no longer allow this because our directors are also participating as players. If a game starts at 7:45PM with an analog clock, that clock will not be replaced or exchanged unless it dies during the game (and even so, will be replaced with the same type of clock if possible). We recommend that you be on time. If either player has fewer than five minutes remaining, neither player is required to keep score any longer, but a complete score is still required to claim a threefold repetition of position, unless a TD happens to have been present for all three appearances of the position at the time of claim. Up to three half point byes are permitted, but these must be locked in before Round 4. Players with identical USCF regular ratings will be ranked in order of their USCF quick ratings. In the last round, if two players with the same score who must be paired against each other have had identical color histories, color will be decided by lot (coin flip, choose a hand, etc.) Past QCC champions 2016: Jay Bonin 2015: IM Danny Kopec & Andrew Ryba 2014: Payam Parhami 2013: IM Jay Bonin 2012: IM Jay Bonin 2011: Andrew Ryba 2010: IM Jay Bonin, IM Danny Kopec 2009: IM Danny Kopec, Andrew Ryba, Nicholas Ryba 2007: IM (now GM) Alex Lenderman 2006: IM Jay Bonin & Ricardo Perez-Billinghurst 2005: IM Jay Bonin 2004: IM Jay Bonin 2003: IM Jay Bonin 2002: Devlin Sinclair 2001: IM Jay Bonin 2000: GM Alex Stripunsky & IM Jay Bonin 1999: Pieter Bierkens, Brian Lawson, Edgar Cimafranca Sr. 1998: Edward Kopiecki 1997: IM Jay Bonin & Edward Kopiecki 1996: Edward Frumkin 1995: Brian Lawson 1994: Joseph Felber & Edgar Ian Cimafranca (aka Jr.) 1993: Anatoly Tonkonogy 1992: Anatoly Tonkonogy 1991: Anatoly Tonkonogy, Bernard Hill & Steven Goldstein Please mark your result on the pairing sheet as soon as your game is over. If you want to analyze your game, you must go to another table that doesn t have any tournament games on it, but there is still no talking permitted until all tournament games are over (we will close within 15 minutes of the last game finishing). We will be using carbon score sheets and will prepare weekly bulletins to be posted online. Please turn in your score sheets to Brian Lawson. We will attempt to have the next round s pairings posted by Tuesday (they will not be absolute, especially for Rounds 2-4 when new players can enter or byes taken). Queens Chess Club membership is required and must be valid through the end of the tournament. Have fun and play well!! Page 1
