The AoChuang makes 5x5 enjoyable . I've done more 5x5 than anything else in the last week. Ao12 of my last 12 was 5:32 with PB 4:08.

I do centres and cross tredges just like Hoya on 4x4. For the tredges, I solve midges like CFOP cross, then fill in the wing edges Hoya-style.

For edge pairing, I start off like 323 on 4x4 but pairing a midge with just one wing on each slice, so it goes like 3222223. Towards the end, the midges already have the other wing attached so it starts forming full tredges. I find that approach easier than doing a whole tredge in each go. Looking ahead for midges is easier because there's only half the places to look at.

For fixing the last tredge when it's in a checker pattern, I discovered that my 4x4 OLL parity alg works as long as I don't turn the middle slice, and append a U2 M' (meaning just the middle slice, not the middle three - my notation is probably wrong).

Anyone else do any of this?

This sounds similar to what I do. My method is:

1. First 4 centres, just like Hoya
2. L/R/B cross edges, same as Hoya
3. Solve either the BR or BL edge in the same way you solved the cross edges
4. Solve that F2L pair - it helps to use either F2 or R' F' R to take the edge out of FD depending on its orientation so you can solve the pair without rotating.
5. Do the same with the other back F2L pair
6. Solve the F centre - this should also solve the U centre, but I find it helpful to only focus on one of the centres.
7. Solve the last cross edge, and try to pair at least two edge pieces together (but don't complete the tredge)
8. AvG edge pairing - I slice with Uw instead of Dw like AvG does. Lookahead is really easy for this step - I often don't have to pause after I get ~1/4 of the way through edge pairing.
9. Petrus 3x3 stage, but you can do CFOP too

My cross edges really suck though - I just can't look ahead or find the pieces I need. Can you look ahead during cross edges? Do you turn slowly, or do you just try to turn as fast as possible? I might try your method for cross edges and see if I find that easier than doing them one at a time.

E: ok so I've done a couple of solves with a variation of your method (start with centres+cross as in your method, freeslice two adjacent F2L tredges and make one pair, fix centres, solve pairs and continue like my method) and looking ahead is so easy, except the freeslice part. This could motivate me to practise 5x5 even more
(I still need to get an AoChuang...)

Yup. I figured that one out as well.

I use standard reduction / free slice but I quite like the look of Hoya. I plan to give it a go on 4x4x4 and 5x5x5 some time!

Nice! There are other tricks or just algs for last 2 edges. Check this page: http://meep.cubing.net/l2e.html
I haven't learnt all algs, but found P-parity and D-parity very easy to learn and use.

Thanks. I am at the point where I do not want to learn new algs.. LOL These parity cases look indeed not so hard to learn.

I know what You mean, I am at the same point.

[kcl]

I may try Hoya on 5x5. I like redux, but I feel like it may be worth it to switch for easier transition to 3x3, and better lookahead for l8e.

Nice times Søren. I see I can only beat you in the main event Everyting else you are 40% faster than me.

I may try Hoya on 5x5. I like redux, but I feel like it may be worth it to switch for easier transition to 3x3, and better lookahead for l8e.

Yeah I want to look into that also.. I need a sheet like this with all the cases for pairing white edges (http://www.ocf.berkeley.edu/~dadams/hoya/) but then for 5X5...

 

[mark49152]

This sounds similar to what I do. My method is:

1. First 4 centres, just like Hoya
2. L/R/B cross edges, same as Hoya
3. Solve either the BR or BL edge in the same way you solved the cross edges
4. Solve that F2L pair - it helps to use either F2 or R' F' R to take the edge out of FD depending on its orientation so you can solve the pair without rotating.
5. Do the same with the other back F2L pair
   

I really like the idea of pairing (tripling?) those back tredges in the same manner as the cross edges. Will give it a go. Thanks. However, I might still solve the whole cross first and see if I can stash the front edge somewhere, because I think it would throw my cross solving to do only three tredges.

Can you look ahead during cross edges? Do you turn slowly, or do you just try to turn as fast as possible?

I always turn slow on 5x5 because I physically can't turn it fast, so actually I find lookahead comes easier. I only solve the wing edges one at a time using 2-3 simple inserts, and during each insert I have enough time to spot the next wing edge. I don't search for the other one matching the front edge - if it's there, great, otherwise I just go for the first I see or the easiest insert, and turn D to choose the right edge. I figured adjusting D is better than pausing and I never have to look or think because I know my cross colour scheme well.

I have a tip for Mark and Gordon, I have found out this trick myself:

Thanks, yes I do the same, but using Sneakly's flipper. I use that a lot for flipping edges throughout pairing. I found that pretty much every case of last two tredges can be either solved or reduced to a single parity tredge, intuitively, using variants of the same slice, flip, slice back approach. So I don't know any special cases for the last two tredges.

(why is explaining things clearly so hard for me)

I tried using your cross method (which is amazing btw, thanks) and because it solves all four cross edges, I've been trying to see where's best to hide the DF cross edge - I usually, after seeing which back tredge I'm going to solve, will hide the cross edge in the other slot. That way, after solving the tredge and then the F2L pair, I still have the cross edge hidden, and I have both the back slots filled, meaning it's easier to find the pieces I'm looking for to solve that other tredge.

I always turn slow on 5x5 because I physically can't turn it fast, so actually I find lookahead comes easier. I only solve the wing edges one at a time using 2-3 simple inserts, and during each insert I have enough time to spot the next wing edge.

I figured adjusting D is better than pausing and I never have to look or think because I know my cross colour scheme well.

My 5x5 is bad half the time, but for some reason it can be very fast for some parts of the solve
Everyone prefers different ways for edge pairing... I hate freeslice even though other people love it, because my lookahead is very bad with it. My lookahead sucks with every other edge pairing method too, except my one, which is why I use it I also never get edge pairing 'parity', which is useful.

and yeah I should probably learn my colour scheme, I still fail 4x4 cross/centres/both way too often...

 

[sneaklyfox]

What do you average on 5X5?

I really don't know anymore and I can't even remember. I never seriously got into 5x5 and I haven't done much solves in a long time. PBs are in link in my sig if you wanna check it out...

 

[Gordon]

Ok. I'm up and ready for competition

Goals:
- Skewb: PBs single and avg, at least one sub-20 single
- 2x2: sub-10 average, sub-8 single
- 5x5: two sub-4:30

Lately I've had some sub-4:00 5x5 times. It would be a nice surprise to get one at the comp.

Here's the link to the results: http://cubecomps.com/live.php?cid=633

Break a leg! I will follow the results!

Three ****ing minutes eighteen seconds for the 5x5!!
