Iacob method

Iacob method Information about the method Proposer(s): Iacob Razvan Proposed: 2023 Alt Names: none Variants: none No. Steps: 4 No. Algs: Max. 146 Avg Moves: 55+? Purpose(s): Speedsolving

Iacob is a speedcubing method invented by Iacob Razvan in February 2023. It relies heavily on algorithms but also on intuition, making this a likable and fast method.

Steps

1. Solve EO and build a pseudo face on the D layer without the DFR corner (EoFace-1C)

2. Solve the E layer

3. Insert the DFR corner while orienting the top layer corners (CLS)

4. Fix parities and permute the last & first layers. You can use PLL on both layers or do PLL and IPFL

WV Variant

1. Solve EoFace-1C

2. Solve 3-Quarter Belt

3. Path A- Make a pseudo pair with the remaining corner and belt edge, then use Winter Variation (27 algorithms) to insert the pair while orienting the to layer.

Path B-Do WV or SV to insert your last pair.

4. Do step 4 as normal.(PLL and IPFL).

Pros

• Rotation less
• Low amount of regrips
• High TPS
• After the first two steps the rest of the solution is algorithmic
• The 4th step is really fast (without pauses) since you can see the IPFL case before permuting the last layer

Cons

• Relies on inspection
• Since block-building is being used in the first step/steps efficiency is needed. If you are not being efficient it's hard to succeed with this method.
• More algorithms than CFOP and Roux combined.(Daylen Hall Variant attempts to lower the algorithm count.)

Improvements

• 1-look last step (PBL)
• Combine the first two steps to lower the move count

Example Solve

• Not really the best solution, but you can get the basics from it.
