International Open Chess Championship

The International Open Chess Championship (IOCC) is played to determine the international open champion in chess. The current International Open Chess Champion is Anish Giri.
== History ==
As a result of Garry Kasparov's split from FIDE in 1993, there were now two rival World Chess Championship cycles. This lead to calls for a unified title, and the International Open Chess Championship was first held in 1996 to determine the strongest chess player in the world. It is one of the strongest chess tournaments in the world and is annually held in a different location every year.
