until this time i write this post. i dont know anything about x-cross. can someone tell me ?

 

[RyanReese09]

it's where when you solve a cross you solve an f2l pair at the same time

if when i'm cubing today and i come across an xcross scramble then i'll post back hre. it is very confusing at first especially to beginner block builders..but once you realize how to do it it's a nifty trick to finish an f2ll pair upon doing cross

not every scramble you do should have an xcross (or a feasible one to do)
it's just something that if you notice it, you should take advantage of it

Anthony's xcross vid. Not bad, taught me a particular way of forming x cross, using keyhole, when you know you'll have one corner solved in the first layer.

@Rpotts
but is 15 sec inspection is enough to think about extended cross move ?

 

[EricReese]

yes, it is

R2 U2 F' D L2 D' F2 D U' R B2 U B R' D F2 L B L' B R F2 R U' D2
for white cross (if you do that) scramble with yellow top green front
upon inspecting i notice this is a very easy scramble. in the UFR corner and the FR edge i see it's a pair there. but alas! blue edge. i notice that an F2 would place the f2l pair in there but with the blue cross peice wher it's supposed to be. i notice that i can just misplace the blue/green cross peice an dthen just M2 U2 M2 the blue/green out.

First i do a D' to align the orange, L to align the red.now an F2 to align the xcross and the f2l pair
y rotation and put the final cross peice in. M2 U2 M2 the blue/green cross peice to swap them. Xcross is done!
very easy sc ramble..there is an f2l pair preserved..and do that..rest of the solve etc..

next

last scramble: R2 L D' B' R2 U L U2 L U2 L2 D2 B2 F D2 U' F U L' F' R L B L2 B
Cross on U.

x2 y2 U' D F R' F R F' D'
double xcross.
do that one time to see what gets xcrossed.

scramble it up again..now actually watch the corner/edge (of 1 xcross pair) to see how it gets xcrossed.

then scramble it up again and look at the other pair and see how that gets xcrossed

very nice bro, i got it now. thanks !

very nice bro, i got it now. thanks !

also id learn keyhole f2l because that's also nice to know to make xcrosses (i use keyhole f2l when i see a corner peice correctly attached to the correct cross edge peice)

Well, it depends how much you practice.
In about 1 or two days, I dropped from 26 ish to 23 ish average by practicing lookahead for a while.

you're smart dude. but i for your information i can memorize until 15 PLL's just in 2 or 3 days .
