Speed Heise-2
| ||||||||||||||||||||||
Speed Heise-2 is a intuitive 3x3 speedsolving method proposed by CriticalCubing and Teoidus in 2017. SH-2 offers an alternate speed optimized approach to normal Heise.

The Steps
1. First Block(FB): Build a 1x2x3 block anywhere on the cube.
2. Square: Build a 2x2x2 Square Block on the D layer. You can either build it on DFR position (Down-Front-Right) or on the DBR position (Down-Back-Right). Both options are viable ones, and choose the one that you can do in the shortest amount of moves.
3. Solve the remaining edges + 2 Corners. If you made DBR 2x2x2, solve the DF edge (and vice versa). Orient all the edges while simultaneously solving 2 corners. You solve 5 edges (orientation + permutation) and solve 2 corners.
4. Last Three Corners (L3C or LTC): Use a commutator which solves the 3 remaining corners.
Pros
- Efficient and low move count.
- Highly Intuitive.
- Easy lookahead due to the intuitive nature of blockbuilding.
Cons
- Since its highly intuitive, it may be difficult to understand and apply for beginners.
