## Dual Commentary with TazzVidz

About a month ago, TazzVidz approached me about doing a dual commentary on his channel. I was a bit skeptical at first. But then I decided that it might be refreshing to do a humble, earnest dual commentary.

I’ve written here ad nauseam that I think I’m a good cuber, but a mediocre speedsolver — dubbing this site a blog for the mediocre. It was in that vein that I did the interview/commentary. He layered the commentary over a video of *him* doing a 4×4 Ao5. I think it came out great:

## Parity or: How I Learned to Stop Worrying and Love the 4×4

After painstakingly modding my Shengshou v4s a couple months ago (mod post coming soon), my interest in 4x4s has waxed and waned. On the one hand, I find it a welcome and more challenging distraction from 3x3s; on the other hand, those damn parity algorithms!?! I have finally committed them to muscle memory and am now trotting along at a 2:20 average using the Yau variation of the reduction method. (For more on Yau, and especially the cross-on-right variation that I find easier, check out Cyoubx’ really good Yau intro video.)

For months, parity was my albatross. I finally conquered it, so to speak, not only by finding and learning algorithms that worked for me, but also my learning about the root causes of parity. This was by far my deepest dive into puzzle theory and its associated patois. Keep reading past the jump for much more on the types of cube parity, what causes each, and, most importantly, what we really mean when we sloppily say that a cube has “parity.”

## PARITY ALGORITHMS

If you’re just here for the algorithms, look no further:

 OLL Parity [1] Rw U2 x Rw U2 Rw U2 Rw’ U2 Lw U2 Rw’ U2 Rw U2 Rw’ U2 Rw’ [2] (Rw Lw) U2 Lw’ U2 Rw’ U2′ x’ U2 Rw’ U2′ Rw U2 Rw’ U2′ Rw2 U2 PLL Parity Uw2 Rw2 U2 r2 U2 Rw2 Uw2

Here’s a (now muted due to copyright claims) video showing each:

## I Got 5 On It

Go ahead and stream the below as your read this post. It’s my strained attempt to find some topical background music consistent with the post’s forced title. Maybe it’s just the introspection of turning 36, but it’s fun to hear an updated version of a song* that we used to listen to in high school.

* Wick-It Remix of the Luniz' “I Got Five On It,” with the opening minute or so cleaved and a line muted to keep things PG-13 around these parts….

So, I received my Shengshou 5×5 yesterday from amazon. I’m not really into higher order cubes, and certainly not into speed-solving them. But I guess that curiosity got the best of me. I wanted to test my theory that a 5×5 actually would be easier than a 4×4 for want of parity issues. I *hate* 4×4 last layer parity — with its long and confusing algorithms. Two 5×5 solves in, my theory seems mostly right.
