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 He played the ...Qd8 line which in recent years has been replaced by ...Qa5 or ...Qd6 at the top level.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.

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.
