+## [2025-10-28 17:36:07]
+- 已修改：
+  - games/gomoku.py - 修复用户识别和显示格式
+- 更改：
+  - 修复 `_parse_opponent()` 方法，使用正确的WPS @用户格式 `<at user_id="xxx"></at>` 进行解析
+  - 修改所有用户显示，从 `@用户{user_id}` 改为 `<at user_id="{user_id}"></at>`，以正确显示用户的群名称
+  - 涉及修改：开始游戏、落子、显示棋盘、认输、列出对战等所有用户显示位置
+- 原因：修复用户识别失败和显示错误的问题
 - 阻碍因素：无
 - 状态：未确认
