Assaubayeva-Tan Draw Keeps Candidates Race Open

The Draw That Mattered

GM Bibisara Assaubayeva and GM Tan Zhongyi split the point in round 4 of the 2026 FIDE Women's Candidates Tournament, but this wasn't just any draw. Playing the Tarrasch Defense with the Classical Variation, the two grandmasters produced a game that showed why this opening remains a viable choice at the highest level.

Assaubayeva, the 21-year-old Kazakh GM rated 2516, came into this round looking to maintain her share of the tournament lead. Tan Zhongyi, the former Women's World Champion from China rated 2535, had been struggling to find her rhythm in the early rounds and needed a solid result to stay in contention.

Opening Preparation

The game opened with the familiar 1.d4 d5 sequence, quickly transposing into the Tarrasch Defense after Black's early ...c5. This opening choice by Tan was particularly interesting given her recent struggles — the Tarrasch is known for giving Black active piece play but at the cost of structural weaknesses.

According to tournament coverage, Assaubayeva reached a position that offered "realistic winning chances, particularly in the middlegame phase." The Kazakh GM's preparation seemed to pay dividends early, as she emerged from the opening with promising prospects and the initiative.

The Critical Moment

The game's turning point came in the middlegame when Assaubayeva faced a crucial decision. Reports indicate she "did not choose the most testing continuation at a critical moment," allowing Tan to regroup and demonstrate the defensive resources that made her a world champion.

Tan's accurate calculation proved decisive in neutralizing White's pressure. The former world champion showed why she earned that title, finding the precise moves needed to hold the balance despite facing a dangerous attack.

The Draw

The game concluded peacefully, with both players having reasons to be satisfied with the result. For Assaubayeva, the half-point kept her in the tournament lead alongside GM Anna Muzychuk. For Tan, it was a crucial result that kept her in the hunt after a difficult start to the event.

This draw exemplified the high level of play in the Women's Candidates — even when one player gets a promising position, the defensive resources available to world-class players often prove sufficient to hold the balance.
