Cross Planning in 15 Seconds: Inspection Techniques

Why Cross Planning Is Transformative

In WCA competitions, you get 15 seconds of inspection time before beginning your solve. Most beginners waste this time staring at the cube without a plan, then fumble through the cross reactively. Elite speedcubers use every second of inspection to plan the entire cross — all 4 edge placements — before touching the cube. This means they execute the cross without pausing to search, achieving 4-6 move crosses in under 2 seconds.

Cross planning is often called the "free improvement" because it doesn't require learning new algorithms or developing new finger tricks. It's purely a mental skill that converts wasted inspection time into tangible performance gains.

Step 1: Find All Four Cross Edges

During the first 3-4 seconds of inspection, locate all four white edge pieces (or whichever color you start with). Note their positions and orientations. With practice, you can snap-identify all four edges in under 2 seconds.

Don't try to plan solutions yet — just find the pieces. Knowing where all four edges are is the prerequisite for everything that follows.

Step 2: Plan the First Two Edges

Focus on two edges that can be solved efficiently together. Look for edges that are already near the bottom face or that can be inserted with single moves. Plan the exact move sequence to place these two edges, including any U-layer adjustments needed between them.

The key insight is that cross edges don't need to be solved in any particular order. Choose the order that minimizes total moves by taking advantage of edges that are already partially positioned.

Step 3: Extend to Three and Four Edges

Once you can reliably plan two edges, extend your planning to three, then four. This is where inspection becomes challenging because you must mentally simulate multiple moves ahead, tracking how each turn affects the positions of remaining edges.

A helpful technique is "influence tracking" — when you insert edge #2, note how the insertion moves affect edge #3's position. If inserting edge #2 brings edge #3 closer to its target, that's an efficient sequence. If it moves edge #3 farther away, consider a different insertion order.

Mental Simulation Tips

• Don't simulate individual stickers: Track pieces as units. Instead of thinking "the white sticker goes here and the red sticker goes there," think "the white-red piece goes to the DR slot."
• Use relative positions: Instead of memorizing absolute coordinates, note relationships like "the white-blue edge is adjacent to the white-green edge."
• Practice without time pressure: Initially, take 30-60 seconds for cross planning practice. Speed will come naturally.

Cross Efficiency: Reducing Move Count

An efficient cross averages 6-7 moves (compared to 8-10 for unplanned crosses). Reducing cross move count requires understanding several techniques:

D-layer adjustments: Instead of aligning edges with their centers using U-layer turns, sometimes it's more efficient to adjust the D layer to bring the slot to the edge. This is especially useful when an edge can be inserted with a single F2 or R2 but the slot isn't in the right position.

Simultaneous solving: Plan sequences where one move serves double duty — inserting one edge while setting up another. For example, a U2 might align edge #2 for insertion while simultaneously positioning edge #3 above its slot.

Extended cross (X-cross): Advanced solvers sometimes plan an "extended cross" that solves the cross plus one F2L pair simultaneously. This is an expert technique that saves significant time when the opportunity arises, but it should only be attempted when the X-cross solution is clearly visible during inspection.

Daily Cross Practice Routine

1. Generate a scramble (use csTimer or any scramble generator)
2. Start a timer and inspect the scramble for exactly 15 seconds
3. Close your eyes and execute the planned cross
4. Open your eyes — if the cross is correct, your planning was accurate
5. Repeat 20-30 times per practice session

Track your success rate. Aim for 90%+ accuracy on cross execution with eyes closed. When you consistently hit this target, your cross planning is competition-ready and you'll notice an immediate improvement in your average solve times.
