3x3 Pseudo-Cross

[jdh3000]

I'm not sure if this is a real thing or if I'm even understanding it. I saw one video about it but may have misunderstood it.

This question is probably geared towards single or dual color solvers.

When faced with a very difficult cross, would this be solving the cross with the colors offset? This is ALL speaking of solve the cross pieces in their relative position before auf.

For example; solving 2 edge pieces opposite to one another, and the other 2 edge pieces fall easier into a position that after auf 2 pieces are solve, and the othe 2 would require M slices to swap. This of course would be only when the cross pieces are in such a bad position that it would justify this.

Another example would be where 2 cross pieces are correctly solved are in their relative correct position adjacent to one another, yet the other 2 insert very easily inserted but in the wrong position before auf. This could quickly be fixed with R D R' D' moves.

Sometimes a cross is so difficult that it seems quicker to me to first throw them in a position that could quickly be solved using a quick alg.

Does anyone do this on difficult crosses? Is this considered a pseudo-cross?

I hope I explained it correctly.

Thanks!

IMO a pseudo cross would only be useful if it's 1 or 2 moves away and has two pieces opposite.

then at PLL step you can influence the case with:

U M2 U2 M2
or
M2 U2 M2

that way, for example, you can choose between T-perm and F-perm

...

I think two piece adjacent has a bad fix afterwards and is not worth it. just learn proper cross, is not that hard.

use infinite inspection if you need

(OFC you can use <R, D> at the beginning to fix cross if it is 1 or 2 moves away, otherwise is not worth it)

Some more algs for influencing PLL:

Pseudo Cross Algs

These algorithms are to solve PLL in a more efficient way while also swapping two opposite edges on the D layer. Solving the cross with two opposite edges swapped can make transitioning to F2L much...

I apologize, i was talking about performing these corrections to the cross before auf, when actually I meant before orienting the cross.

Such as:
(Another example would be where 2 cross pieces are correctly solved are in their relative correct position adjacent to one another, yet the other 2 insert very easily inserted but in the wrong position before auf. This could quickly be fixed with R D R' D' moves.)

Yes, that wouldn't be any good at all, but what I intended to say was making this pseudo cross and fixing the 2 pieces quickly before cross orientation, or even after 2 pieces are orented.

If I'd use the correct terms before posting it would give everyone something to work with.

It's not too good, but it is regripless and cool:
S' M' U M U2 S (DF-DR & UB-UR)
