Philadelphia knocks out New Jersey - Kavinayan P. Sivakumar

The Philadelphia Inventors’ first match of the 2010 season resulted in a 3-1 win against New Jersey Knockouts . The chess pundits did not put their money on Philly considering how New Jersey dominated the league last year. However, Philly fans were awarded for their loyalty to their team in this match. With this first step in the direction towards the playoffs, the Inventors also have gained confidence and more respect around the league.

FM Tommy Bartell led the team from the beginning with a win over GM Boris Gulko, who tasted his first defeat in USCL after an impressive 8-0 run. IM Bryan Smith fought a valiant battle against GM Joel Benjamin. Unfortunately he could not convert it into a helpful result. FM Karl Dehmelt scored against FM Arthur Shen. He offered a rook sacrifice. Arthur Shen correctly declined it. However, Arthur's king was not having good cover for the rest of the game which cost him the point. IM Richard Costigan played a quiet line on Scandinavian defense as black against Sean Finn. He played the ...Qd8 line which in recent years has been replaced by ...Qa5 or ...Qd6 at the top level. Still, Costigan played to his strengths in converting the end game to a win.

I have annotated two games from this match.

14...Ne4 15.0–0 Rfd8 The rook looks menacing as the white bishop and white queen are its future targets.

16.Bg5 Nxg5 17.Nxg5 h6 18.Ne4 cxd4 19.cxd4 Qd7 20.Nd6 The knight's manuever has gotten it to the sixth rank. However, Bartell makes sure it is uprooted as quick as possible.

20...Nc7 21.Qg4!? This move concedes Black a slight advantage.

[21.Nb7 Rdb8 22.Nd6 Rd8=; 21.a4 (Stopping Nb5) 21...Ne8 22.Nxe8 Rxe8 23.Qd3 Red8 24.Rfd1 =/+ Deep Junior]

21...Nb5 22.Nxb5 Qxb5 23.h4?! Possibly a little careless. Now Black's queen will infiltrate.

[Simply developing the rook 23.Rac1 would still not ease the pressure because of 23...Qd3]

23...Qb2! 24.Rad1 Qxa3 25.Rfe1 Qf8 Now that black has a definite advantage, he wants to consolidate and make sure white gets no counterplay. This move brings a piece near his king.

26.f4! Gulko doesn't give up! This move prepares the f5 break with a potential kingside attack or tries to eliminate the e6 pawn, so the d pawn can become a dangerous passed pawn.

26...Rd5! The d pawn is blockaded.

27.f5 exf5 28.Qxf5 Rad8 29.Qg4 Qe7 30.e6! fxe6 31.Rxe6 Qd7 32.Kh1 This move also illustrates the safety of white's monarch. After the f pawn is gone, and because of the h pawn's advance, there seems to be a lot of space around white's king.

42.Kh2 Rf4! Here, you can see the weakness of the white king. With no h pawn, there is no cover for the king.


[43.Rxg7+ Kxg7 44.Qd7+ Rf7 45.Qg4+ Kh7 46.Qe4+ Qf5–+]

43...Rh4+ 44.Rh3 Qf4+ 45.Kh1 Rxh3+ 46.Qxh3 Qc1+ 47.Kh2 Qb1! Stopping all checks.

Congratulations to Tommy for winning a fantastic game. However, Gulko fought until the very end, and used every resource given to him. Overall, it was an amazing game that I enjoyed watching!

Lets move on to the next game.

11...g6 12.Re2!? Bg7 13.Qe1 White stops Black from castling momentarily.

13...Nc8 To defend the e7 pawn, Arthur decides to bring his knight back. However, this knight will stay on c8 for the remainder of the game.

14. Bg5 0–0 15.Qd2 Re8 16.Rae1 Black may be up a pawn, but his rook on a8 is still asleep!

16...Qd7 17.h3 a6 18.Bh6 b5! Arthur reacts actively to white's progress on the kingside. He hopes to open up the a-file for his a8 rook.

19. Bxg7 Kxg7 20.Ng5 bxc4 With this move, Black hopes to make the d5 pawn a weakness.

However, 20...Nb6 maintaining the tension and also activating the knight would have also been good. 21.b3 bxc4 22.bxc4 h6 And Deep Junior even thinks that black is slightly better here.

21.Nxc4 Qb7 22.Ne4! White has the iniative here.


[22...Nxd5?? 23.Na5+-; 22...Qxd5?? 23.Nxf6!+-]

23.Rxe4 For just a pawn, white has tremendous pressure on the d6 and e7 pawns.

23...Qd7 24.Rh4! h5 25.Rxh5!! Rh8 Arthur correctly sees the danger in taking the rook.

[25...gxh5 26.Qg5+ Kf8 27.Qh6+ Kg8 28.Re3 h4 29.Re4 Qf5 30.Rg4+ Qxg4 31.hxg4+-]

26.Rxh8 Kxh8 27.Qh6+ Kg8 28.Qg5 Rb8 29.b3 Kg7 30.h4! With almost all of Black's pieces on the queenside, it is no surprise that White starts a crushing attack on the kingside.

30...Qf5 31.Qd2 White should keep queens if he wants to attack.

31...Qf6 32.Qa5 Ra8 33.h5! gxh5 34.Qc7 Qc3 35.Re3 Qb4 36.Rg3+ Kf6 37.Rf3+ Kg7 38.Qd7 Qe1+ 39.Kh2 Na7 40.Qf5 f6 41.Rg3+ Kf8 42.Qg6 1–0

Dehmelt played very nicely throughout the whole game. His pawn sacrifice let him obtain the e file for his rooks, and the placement of his knights helped him to get important squares under control. The c4 knight, for example, kept the c8 knight out by not allowing it to go to b6. However, Arthur played active as well, such as b5. He correctly did not take on h5, and this gave him some chances. But White's attack was too great and the fact that the a8 rook and the c8 knight were out of the game was not good news for Black. Overall, it was a nice game by Dehmelt and Shen.
