The 2026 Zina Koodrin Memorial Checkmate Weekend in Adelaide reaches its halfway point with Round 3 underway. This Swiss tournament draws strong local and interstate talent competing in the six-round Open section. The 90-minute main time with 30-second increments favors prepared players who can convert advantages without time pressure. Adelaide chess has rarely hosted events of this caliber, making the Koodrin Memorial a genuine opportunity for players to test themselves against quality opposition and build rating points heading into the second half of the year.
