TSSH is a speedsolving method designed for big cubes. It was proposed by Sundararajan(V Achyuthan), Shyam, Minh Triet and Nguyen for the August Method development competition. This method is used to apply the CFOP or Petrus method to the 4x4 puzzle but can also be used for bigger cubes.

Steps

Step 1 : First you build 2 opposite centres.
Step 2 : Do a Z rotation and then solve 2 adjacent edges of the left side. (yes it is strictly adjacent edges)
Step 3 : Finish all the centres and align the 2 cross pieces you solved previously to their correct centres.
Step 4 : And then you pair up the edge of the F2L pair that goes between the two cross pieces and their centres and then insert the F2L pair by pairing up the edge with the corresponding corner.
Step 6 : Then you pair up one more cross edge and insert it into its spot.
Step 7 : Then you complete a big 223 block like the second step of the petrus method and keep it at the back.
Step 8 : After that you pair up the last cross edge and solve it into its spot.
Step 9 : Then you pair up the rest of the edges and solve it like a normal 3x3 (and parity if there is one).

Pros

This method could be beneficial for those who main petrus or anybody who uses CFOP and wants more pieces solved when arriving at 3x3 stage. Since most of the cube is solved while arriving at 3x3 stage, It leads to better ergonomics and fast turning.

Cons

This method requires a lot of mid solve look ahead (but can be made better with practice)
