推荐的先决条件
为获得最佳效果，请先学习全部57个OLL公式。PLL通常是CFOP方法的最后一步。 学习所有OLL情况
PLL识别至关重要
快速PLL识别对速拧至关重要。与OLL观察顶面不同，PLL识别需要观察最后一层的所有四个面。
- 寻找车灯（相邻角块上的两个匹配颜色）
- 检查已解块（2x1的匹配颜色条）
- 计算已解面的数量（0、1或2）
- 首先使用两步PLL方法学习识别模式

学习策略
- 从两步PLL开始（棱块用Ua、Ub、H、Z；角块用T、Ja、Jb）- 这7个情况可以解决任何PLL
- 四个G-Perm（Ga、Gb、Gc、Gd）是最具挑战性的 - 把它们留到最后
- 从所有角度学习PLL识别 - 旋转魔方找到最佳观察角度
- 许多PLL有更快的替代公式 - 实验找出适合你转动风格的公式
- 使用收藏功能跟踪你正在学习或想要多练习的情况
识别训练
快速识别PLL情况是一项需要专门练习的技能。以下是关键策略：
识别策略
- 车灯： 同一面上的两个匹配角块颜色（例如，两个红色角块相邻）。车灯出现在Ua、Ub、T、Ja、Jb、Aa、Ab和某些G-Perm中。
- 已解块： 一个面上的2x1匹配颜色块。块是识别J-Perm、R-Perm和G-Perm的关键。
- 已解面数量： 计算有多少个面的两个棱块都与中心块匹配。这可以快速缩小可能性。
- 两步识别： 首先学习区分仅棱块情况（Ua、Ub、H、Z）和角块交换。这为完整的PLL识别奠定了基础。
