Alan Lasser's Game of the Week
Black was likely quite content with his position until the stunning 15.Bh6 appeared on the board. Where did that move come from? In the shock, the best defensive continuation was not found and things just got worse after a poison pawn was taken on move 23. Sure, the position looked bad when resignation came on move 30, but Stockfish had to tell me exactly why.

Former Wachusett CC champion Carissa Yip
beats ex-Women's World Champion Ushenina
Carissa Yip, the 2014 champion of the Wachusett Chess Club, got off to an excellent start in Round 1 in the Women's Division of the 2019 World Team Championship in Astana, Kazakhstan by defeating former Women's World Champion GM Anna Ushenina of Ukraine on Tuesday, March 5th. The 15-year-old Women's International Master from Andover, Mass. beat 33-year-old Ushenina with the black pieces on board 4 in the USA vs. Ukraine match, which ended in a 2-2 tie. Carissa scored the only win for the U.S. team, with fellow team mates WGM Tatev Abrahamyan losing on board 1, WGM Sabina Foisor drawing on board 2, and 12-year-old Woman Candidate Master Rochelle Wu splitting the point on board 3. -George Mirijanian

The blockade on c5 did an amazing job of blunting the doubled rooks on the c-file and bishop on the g1-a7 diagonal. Black's bishop activation g7-f6-d8-a5-b6 was the highlight for me. Had White done nothing, Black could have expanded on the kingside with f5 etc., but she paniced with b2-b4, axb3 ep, which left White with a weaker queenside than Black's (a3 vs b5) and gave White a tough position to hold. It is also interesting to see the engine award White an advantage out of the opening (space) but no clear way to maintain it.

Game of the Week
It looks like the weak Black queenside pawns will be over-run. Amherst College student Alexander Deatrick’s crucial move to co-ordinate a rally was to place the Black knight on the worst-looking square on the king side, 20…Nh8, in this last round game that determined the winner of the 94th annual Western Massachusetts/Connecticut Pioneer Valley Chess Championships.

UPCOMING USCF CHESS TOURNAMENTS
RECENT CONNECTICUT CHESS NEWS
REPORT - 2019 EASTERN CONNECTICUT OPEN
YELFRY TORRES of Enfield, and ROMAN RYCHKOV from NJ (student at UConn)
tied for first when each finished with 3-0 scores. 23 were entered
into the competition which was held Feb 23 in Coventry Connecticut.
Rob Roy served as TD. We thank Dan Smith, from Westerly RI, for arriving
extra early to help Rob set up all the tables and chairs. It is this
kind of generous spirit we would like to see more of from others.
We are hoping for a similar turnout for this Saturday, March 16, for the
2019 Greater Hartford Open.

Pitted against the machine programmed by humans, the machine’s machine now has a two game lead in the TCEC 14 Superfinal. There was a long series of draws from game 30 to 48 where it seems the neural network took the measure of its opponent.
Just like there were some interesting draws in the Carlsen-Caruana classical match, the programs gave us this 135-move game(the last fifty moves were omitted here because the machines just dance around an obviously drawn position). Each side is after the other’s king with a queen-led attack. It appears that Leela will have at least a perpetual check while the best Stockfish can hope for is a perpetual on the other side of the board. Both sides must calculate queen checks and king moves and pawn promotions. Incredibly, before either attack even develops, Stockfish has apparently seen the whole thing and on move 33 evaluates the position as equal, an opinion it maintains all the way to the finish.

When Stockfish first went to +0.12 on move thirty, it seems likely that it had actually calcuated fifty moves ahead in these variations.

TCEC Superfinal is underway, a 100 game match between Stockfish and LCZero(aka "Leela”). This is the pairing that the fans have been waiting for, it could answer answer some questions because LCZero is the first artificial intelligence program to make it to the finals. You may recall a few years back AlphaZero's non-tournament trouncing of an outdated Stockfish program, on the one hand it was a significant achievement and on the other hand it was a set-up mismatch. The TCEC rules approach make it a more equitable competition between AI and traditional chess programs.
The relevancy question for consumers still persists, only a few can afford the hardware/software combinations that make this level of play possible. Even more confusing at the retail level is that Houdini recently beat Stockfish in a TCEC game/30 tournament. My computer science friends at UMass claim that the shorter time limit match result changes nothing, sometimes the lower rated player wins, they remain convinced that Stockfish remains the strongest program at the game/120+15 time limit of the TCEC Superfinal, or for the unlimited time analysis you might want to do at home. The difference between the analysis of a 3600 rated program and a 3500 rated program is unlikely to be useful over the board. The long variations are more meaningful if you are a correspondence player; in that case you should still get the most powerful combination you can afford and just accept that Moore’s Law means, in a few years, today’s computing purchases will seem like a costly indulgence in antiques.
There is a new TCEC approach to some of the opening selections, throughout the match each program gets to play the same opening, one game as White and one as Black. Previously the opening selections for these contests were dynamic positions of rough equality that had a tendency to develop into actual equality. In this match, the computers are given some starting positions where one side has an apparent opening advantage. The starting point for these two games is really move five, LCZero tried 5.Be2 and Stockfish went with 5.Qe2. This was the first full point of the match, Stockfish managed to hold the bad position and Leela could not.
LCZero(3460)-Stockfish(3588)

Hello Weston/Wilton parents,
We just started our ten weeks of free DIG Chess classes at the North Branch Bridgeport Public Library and it was a GREAT turnout. This program is funded by the Starbuck Foundation. The next nine Saturdays, Coach Erin will be there teaching from 11am to 1pm. Kelvin Green, a Weston DIG Chess player, was also there teaching.
Please let me or Coach Erin know if your son or daughter would like to go help teach. There are lots of beginners there that need individual attention regarding how the pieces move on the board so any help would be great.
