The Bobby Fischer Ultimate Chess Set has a long and storied history. The pieces are ergonomically engineered to feature smooth surfaces and seamless edges to make extended games comfortable and a joy to play. The large-headed pawns and bishops, and the grooved knight's stem are easier to grasp. Heavy and durable, this set became the iconic plastic chess set here in the United States. Premier weighting system designed to last longer than other weighted chess sets. Additional protection to keep the weights from loosening up or falling out.
