This alone has insane amounts of info and will keep you occupied for months probably.
Concepts like Edge orientation, block building, premoves, NISS, insertions etc. are all very important.

Once you get those "basics" down you probably want to learn Domino reduction too.
This
is great for that.

After DR you want to learn Half Turn Reduction too which is basically just doing a DR on another axis with some limitations. However there are lots of tips and tricks but unfortunately I couldn't find a clear document about that topic while starting to learn it a month or so ago. I might write something about it myself after I have practised some more with it.
alright, i think i'll start getting into fmc soon, thanks for the resources

I just tied my FMC PB and I'm pretty happy with it. Any advice is more than welcome since I'm kind of a beginner to FMC.

Well, I'm not an FMC expert, so I won't comment on most of the solve, but insertion finder says your insertion can be three moves better with a perfectly human-findable commutator.

ok so at this point I know I have at least a 6-2 (at the very end), so a 30, which isn't very good so I tried looking for other things, and end up finding a 22 to 2e2e+e, so that seems more promising, turns out the best I could find is 8-0 which left 30 to e, which is worse than 30 to solved, but I spent all my time on trying to insert the 2e2e, so I quickly return to the solution I had written above and with less than a minute left inserted a 6-0 (didn't have time to do the right version of the alg which would have given 6-2. anyway glad I didn't DNF it, but overall horrible solve. moral of the story, if I see a 30 I should just write it down just in case even though it's bad, I get a bit too obsessed with throwing out ~30 move solves early on because I think I'm gonna find something better.
U D2 B U2 F2 U' F2 U2 D' R D' B2 D L2 U [1] L2 D2 L2 R2 U R2 U' F2 B2 R' U
[1] = U2 F' B L2 F B' (6-0), although actually a 6-1, but I didn't have enough time to write the cancellation
F B' U2 F' B L2 would have given the 6-2

I'm pretty happy with this one, although IF found a 21 with a 8-6 and a 6-6, I need to start trying to use two algs for one alg cases like 2e2e more often.

so with this one I am pretty disappointed in the insertions, I was trying to slice it down, but I wrote some parts of it down wrong, and also kept misscrambling so kinda ran out of time to slice it down, could have been a 22 if I was able to.

overall I'm glad I didn't DNF the first solve (I had though I wrote down the insertion wrong, but thankfully didn't), and was able to get PR mean and get my first FMC win! Looking at this my best possible mean (if I did optimal insertions) was 30,21,22 = 24.33, so I know I have a lot of room for improvement in the future.

bonus! on the last one the optimal solution follows a logical DR solve and uses one of the EOs I had written down, obviously nobody found it, but I believe that if enough people were doing this scramble, or it was in a week long FMC competition, someone would have.

You have not correctly copied your working to your final solution. I have corrected it accordingly above.
I would suggest, since you can build F2L-1s to start learning skeletons and insertions as it is much more efficient than LS > OLL > PLL. If you already know commutators this should be easy. I would recommend learning from this tutorial: https://fmcsolves.cubing.net/

thanks for the reply, I will have a look at skeleton and insertions. Appreciate it.

Hey Guys
I am trying to learn insertions now, but I have difficulties with the comutators, does anybody know a good toutorial which also covers cases with twisted corners and such things?

Hi, I am a beginner at FMC, Id say i average somewhere around 40 moves. Yesterday though, i finally got something decent. Ive read most of trontos tutorial and its very helpful, lots of head knowledge but I havent put in enough time to make it show. The example solves, whilst i understand the techniques used, still look like luck to me so Ive got a ways to go yet. Anyway, i got a 23 move solve (pb by a mile, previous was like 35 or so).

Scr: D2 F D2 U2 F U2 B' R2 B2 L2 F' U2 L R U' B' R' B F D' F2

only 4 misoriented edges for DR on yellow/white (im not yet colour neutral for DR, it trips me up still), but I always struggle with the corners and edges, as a result it often takes me another 10-12 moves after EO to achieve DR. So I head to the inverse scramble and find this

(U2 L2 D' F) //EO
(L F2 U2 R' U2 R) // DR
fastest DR ive ever gotten, although it doesnt look too great, so I head back to normal scramble (yes i checked the other trigger, found nothing good there)

new scramble:
R' U2 R U2 F2 L' F' D L2 U2 + scramble
and the thing is practically solved (by my standards, usually its a mess still)!

I found this skeleton leaving 3c 3e:
(U2 L2 D' 2 B2)
discarded this since i dont know how to do a 3c3e insertion properly, i just go fix the edges cause theyre all in the E slice, so I simply adjust my skeleton to fix those edges with a couple E moves :
U2 L2 U D2 F2 R2 U' D //3c

transferring into actual skeleton with no premoves:
U2 L2 U D2 F2 R2 U' D R' U2 R (*) U2 F2 L' F' D L2 U2 //3c (18)

best insertion i could find cancels 3 moves, i havent done much practice with them and only really know a few general commutators:
(*) = R D' R' U2 R D R' U2

sol: U2 L2 U D2 F2 R2 U' D R' U2 R2 D' R' U2 R D R' F2 L' F' D L2 U2 (23)

This took me about 7 hours and was really draining but it was all worth it in the end. If anyone has feedback or something better, feel free to let me know.

I'm never active here so here are some cool solves from Northeast Champs a couple weeks ago:

F2 B' U R // EO
D F2 U L2 D F // DR (10)
D' B2 L2 D // HTR (14)
* B2 R2 L2 ^ U2 D2 // 3e+slice (19)
*: D2 B2 L2 B2 D2 B2 L2 B2
^: R2 U' D B2 U D' // lazy 6-4 for slice
then shorten part after DR to Dw' B2 L2 D' B2 L2 B2 U' Uw' F2 L2

R' U' F D2 R' F2 L2 U2 L' B2 L B' F' U R' U L' R2 B R2 F U' R' U' F

(U' B U) // EO
(L F) // DR-2c
(R B R' F2 R B' R' F2) // comm to get DR temporarily
(L2 F2 U2 R) // HTR
(* F2 U2 L2 D2 L2 D2) // 2e2e
*: (R2 F2 L2 B2 L2 F2)
then remove comm and do 8-3 to solve corners

Just got a "PB" (my best solve at home ever, still worse than my offical 16)

Scramble: R' U' F D2 F' L F' R' F2 L B' D R F2 L' D2 L2 F' D2 R' U' F
Solution: U B2 U L' U' B' D' R2 D2 R L' U' L U R' D2 U2 L2 (18)

U B //321 (2/2)
(L2 U2 * R2) //Blocks (3/5)
B L' B' //F2L-1 -1 move (3-1/7)
B L U L' U' B' D' //3e4c (7-4/10)

* = D2 R U' L' U L R' D2 //Setup to sexy (8/18)

Are there any websites where you can practice FMC with unlimited scrambles? The ones that I found were only weekly scrambles, I want to get more into FMC so I wanna practice more.

Do we have a formula for edge commutators not using slice moves?
What do you mean?

The short 3-cycle edge comms of the interchange-insert type have to use slice moves, because that's how you can isolate a single edge piece. The only other useful edge comms are the M' U2 M U2 type, which also use slice moves (but keep in mind that you can "split up" one of the slice moves without affecting move count, e.g. M' U2 M U2 = l' U2 M U2 L, both six moves long).

There are short 3-cycle algs that are not commutators, e.g. (R2 U' R2 f2)2 or (R2 u' R2 f2)2. There isn't exactly any rhyme or reason to how they work; they just do.

You can just get scrambles off csTimer or whatever.
