Using Fewest Moves w/ Fridrich Variation

[pjk]

For those of you who solve mostly with Fridrich, how do you go about the fewest moves contests? I know that you want to try building the F2L in blocks, but any special techniques for the LL? What techniques/tips overall to use have for fewest moves? Thanks

I have been wondering the same thing!
I tried to count an average run of mine. its between 40 and 50 turns
is this good?

I just joined the "Fewest Moves Challenge" at Yahoo. There is sooo much info there!

As for me, when I solve normally I try and solve the best F2L I can.

Then for the last layer, it is good if you have 1 corner and 1 edge already solved. That allows you to look for a 3 edge cycle and a 3 corner cycle insertion.

An insertion is basically "inserting" into the solve the 3 cycle of corners/edges so that it takes less move at that moment than if you had to solve it like a normal speedsolve (= after everything = non optimal solutions).
Thus if you have 1 corner and 1 edge solved, you can try to insert into your solution an optimal 3 cycle of edges ( 6 moves ) and an optimal 3 cycle of corners ( 7 moves ). (and these move counts can be reduced with move cancellation)
In order to do that, all you need is stickers that you can put on the pieces you want to cycle so that they are easier to recognize and find the best place to "insert" the cycle of corners/edges.

That's a very good way to do it.

gillesvdp is right. If you do what he does, you can probably get as low as 75 moves

Or did you also use Thistlewait for that at the Czech Open?

I just joined the FM YG. What a coincidence that a made this post shortly after you joined...

Yes I used Thistlewait at the Czech Open.
My best time for this method is now 43.xx seconds.

But I will never use it ever again for Fewest Moves. Next time, I will use my normal method and try and break the Belgian Record (36 moves).

I just couted another random fridrich solution. 48 moves.

am I doing anything wrong here? just regular fridrich with no shortcuts or fancy tricks

So that is pretty good.
That is why only the 10 worst results in Fewest Moves competition have been equal or bigger than 50 moves. ( http://www.worldcubeassociation.org...gionId=&years=&show=100+Results&single=Single ).

... Ok so this means your solution is close to the 10 worst official solutions ever done but in general, for a regular Fridrich, it is not too bad.
Keep going !

PS: My 75 move solution was done using a very special method which is supposed to be very good for FM, but only if measured in STM. I can say that I did this FM competition for fun mainly.

I got my 47 moves solution using a lot of fancy tricks for F2L (Cross + 3 pairs in 12 moves), but because I don't know OLL or PLL I ended up using 35 moves for the last pair + OLL + PLL. (keyhole + very bad 4 look last layer (no edges, z-perm) regular solve gave me 76 moves)

I read somewhere that a regular Fridrich solve was about 55 moves and a regular Petrus solve was about 45 moves.
Fridrich: 7 (Cross) + 4*7 (F2L) + 10 (OLL) + 10 (PLL) = 55.

I thought the average move count for PLL was 12, and OLL 9

You might be right, I didn't check exactly. I don't know OLL+PLL, but I think PLL's are indeed longer than OLL's.
