Going from Petrus to Fridrich

[Poobslag]

I've been solving with Petrus for about five or six years and my average is around 45 seconds. I want to try the Fridrich method but I'm confused as to how people begin with the last layer. All of the Fridrich web sites I've found skip any sort of beginner techniques, and just describe the 40 OLL and 21 PLL algorithms... Do people really memorize these algorithms to just get started with Fridrich, or are there some stupider shortcuts I can take to get started?

I'm also curious to hear whether anybody else has had success getting faster after switching methods or whether it's a big waste of time

Learn the corner and edge cycle PLL's. Learn the 7 OLL's that already contain the cross. It cuts down the total to 11 algorithms and you can learn more algorithms to get faster if you want.

 

[Johannes91]

For LL, you just need to learn to orient the edges. Then you can do it the same way as in Petrus.

If you are good at Step 4b, Fridrich F2L shouldn't take long to learn.

I tried switching methods but it didn't work for me. It has worked for others though. I think Thom went from petrus to roux and he is really fast with it now.

For bare essentials all you need is two PLL's and two OLL's. But then work from there on more algorithms.

People learn the algorithms step by step

Go to this thread for steps on how to learn Fridrich. It is in the process of drafting right now, but it has all of the basic concepts.

Macky's site has an excellent guide on getting started with Fridrich

i have a frid tutorial for intutive f2l

I almost exlapin evrything but its longgggg video

Alright cool, that's what i figured. i'll just learn the two orientation-preserving PLLs I didn't learn from petrus, and some of the edge OLLs, and build from there.

don't switch! I regret my switch. I was too stupid to finish learning petrus, so I came up with a 4 look last layer fridrich. It was easier to think of f2l as pairs than block for me.
Petrus and Fridrich uses the same last layer techniques I don't see your trouble. Just use FRUR'U'F' to orient the edges and do what you did before.
I believe you are doing 4 look last layer as of now? then just learn all the PLL for 3 look last layer. please explain more clearly how do you do last layer now.
Why are the noobs slower than you responding?

If you can average 45 using pure petrus, then don't switch at all. LL is essentially the same for both methods.

 

[Poobslag]

please explain more clearly how do you do last layer now.

For Fridrich, I'm orienting edges/corners as 2 steps, and then positioning corners/edges as 2 steps. i'll combine these as I learn the OLL and PLL algs

I wanted to switch from Petrus to Fridrich because it seemed like I was spending 4 steps orienting and positioning the last layer (if you include the edge-orienting task during Petrus F2L) whereas Fridrich only uses 2 steps.

 

[Lofty]

well If you look at Petrus's site you will see he has other options for the LL...
you can learn step 5+6 at once step 6+7 at once, step 5+6+7 at once or his 2 alg 1 look 5+6+7.

When people start to learn the last layer of Fridrich, they usually start out by learning 4 look last layer, meaning solving the last layer in 4 steps, and that is what you're doing. Then, after the Fridrich users are good with that, they turn it into a 3 look last layer and finally into a 2 look laster layer. Petrus users can do it exactly the same way (except starting out with a 3 look last layer), and why that is will be explained below.

As explained before in this thread, the last layer of the Petrus and Fridrich Method is almost the same. The main difference between these two methods is solving the First Two Layers. So when you're saying you want to solve the last layer in two steps, you don't have to switch to Fridrich. You can solve the last layer in 2 steps with Petrus, but you just need to learn the algorithms. So when you say you want to switch to Fridrich, it sounds like you want to do the F2L differently. That's really the only thing different about the methods. So if I'm hearing correctly, if you don't want to change the way how you do your F2L, don't switch your method, just learn the algorithms for the last layer. Learning the algorithms for the last layer doesn't mean switching to Fridrich, as you can do the last layer for Petrus and Fridrich in the same way. I hope that wasn't too confusing and it helped you!

No, they are not. Edges are always oriented correctly in Petrus, which means that 2-look requires a lot less algs than in Fridrich.

Hopefully, you'll do it again and again and again, because each time it gets viewed by an updated audience. It was good information when you wrote it, and it continues to be good information each and every time you repost it.

How many moves would petrus with ZBLL take on average speedsolving?

 

[Lofty]

well lets say you do F2L in 30 moves. It is possible to do less but just to give you a number I'll say 30. Add 12.xx and you get 42.xx
I think the only thing with less moves would be PHZB...

 

[CanadianPires]

@Lofty - Isnt that exactly what PHZB is? Petrus F2L + ZBLL?

 

[Lofty]

PHZB is solving F2L minus 1 pair- You do this kinda like in Petrus + Heise. 2x2x2 to 2x2x3 to F2L minus 1 pair.
ZBF2L then ZBLL.
The difference is you skip step 3 of Petrus and then do step 4b with ZBF2L
