2-Sided PLL Recognition

Faster PLL identification from two visible sides and top layer.

Goal

Instantly identify PLL case before AUF with minimal cube turns.

Prerequisites

• Basic full PLL knowledge
• Familiarity with headlights, bars, and solved blocks
• Consistent OLL completion with stable viewing angle

Step-by-Step Tutorial

1. Step 1: Learn recognition hierarchy: corners first (headlights/adjacency), then edges (bars/opposites).
2. Step 2: Build if-then cues. Example: “headlights on left + back bar -> likely Jb/R family.”
3. Step 3: Practice with random PLL trainer using fixed camera angle to avoid unnecessary y rotations.
4. Step 4: Pair each recognition cue with exact AUF and alg start trigger.
5. Step 5: Time recognition only (no execution) to train raw identification speed.
6. Step 6: Integrate into full solves and track PLL pause time in session stats.

Practice Drills

• Recognition Flashcards: identify 100 random PLL screenshots per session.
• No-Rotation PLL: solve PLLs without y turns whenever possible.
• AUF First Drill: call AUF before first algorithm move.

Common Mistakes

• Starting alg before final recognition certainty
• Overusing y rotations for comfort
• Not distinguishing similar mirror cases (Ja/Jb, Ra/Rb)
