Alan Lasser's Game of the Week

  Check out the position after move twenty-nine;  talk about unbalanced material, White’s four pieces are completely different from Black’s three pieces, throw in a couple of extra pawns and try to figure it out.  The computers at the TCEC 10 are certain the position is equal at all times.

Alan Lasser's Game of the Week


Long-time readers have seen my version of the World Champion Lasker’s classic advice, “Four Things to Think About Before You Touch That Chess Piece” in this column many times, lastly in the issue of 7/22/17.  If I may quote myself, “the best chance for laying a successful trap is to place it as close as possible to your opponent’s intentions”.  “How do I do that?”, you might ask.  This game is a good example, 17…Nd5 is an objectively stronger move, but I chose to play 17…g5 in order to lay a trap.  My opponent’s intention is to play Rc1, combining with the bishop to attack my knight on c6, at the very least it will smash up my king’s defensive position.  17…g5 does not appear to prevent that, it looks like the bishop need not be defended because the rook’s attack on my queen will allow his plan to get underway immediately.  Then my intermezzo capture, 18…Re1, springs the trap, because the rook must be recaptured.

    Connecticut Scholastic Blitz-Chess Championships

    ================================

    Dear fellow chess organizers in Connecticut,


    I will continue organizing my small USCF Saturday tournaments in Coventry every month for as long as I can.  A total of 92 players have participated in my program since it was started May 2016.

    We are fortunate here in Connecticut that Bill Goichberg runs top-notch chess tournaments in Stamford, Windsor Locks, and Sturbridge Mass. on a regular basis.

    We need a big annual event in downtown Hartford, with media coverage, conducted by a team composed of all the local organizers and tournament directors.  A large one-day event for adults, with a separate section for Juniors. Maybe Spring 2018 ?

    I will coordinate all the volunteers needed to conduct such an event. I will be backup for any function when it is needed. I can use help with acquiring the site, arranging for the date, sending details and reports to the USCF.

    I am unable to do all of this myself, so volunteers are needed to jump onboard early on in the process.  I need TD's to commit to serving as floor directors, and pairing directors. I will award each volunteer with free entry.

    Do any of you have influence with the people at the new UConn facilities in downtown Hartford ?  We would all together decide on the format, time control, entry fee, and prizes etc...

    Yours In Chess,

    Rob Roy, USCF Senior TD
