Game of the Week, by Alan Lasser. Plus more...

Good news chess fans, 2461 rated Yixin Li has returned to UMass this semester and he intends to play in more USCF tournaments. He had a lot of fun at the Chinese national team tournament this summer. In this game he had to navigate through one of those treacherous more-pieces-than-pawns positions to score the point.
