10/10/10 scramble :D So no linear sub6 EOs...

L U' L2 R' D //EO 5/5

Not that many linear sub6 move EOs so I decided to look for rzp in 6 quite early on and got lucky with 10 move finish.

R D2 R' F2 D2 R' F2 R'^ //HTR 8/17

Such an annoying scramble. Wrote down more than 10 different sub12 move DRs but all were 4-5qt except one that was 4a2 8e :D

Damn. My DR is 21 optimal... I suck

(D R L') //EO+rzp 4c4e
L2 D' F2 B2 U2 D B //2c4 7/10
(D' L2 U^ B2 U' R2 U^) //HTR 7/17
(F2 L2 U2 B2 R2 D2^) //slice 6/23
^=w //+0/23
optimal from DR.
Variation R2 B2 U F2 B2 U F    // drud-eolr  (7/10)
has a 21 but I missed that variation

D2 B2 L //EO+rzp 7c8e
(R2 L2 F' U B D') //2c3 4e 6/9
B'^ (R2 L2 B' U2 F2 U2 B'^) //HTR with standard +2 extension 8/17
(R2 B2 L2 D2 L2) //slice 5/22
 ^=w //+0/22

DR is 21 optimal with 1 HT -> 4b2 2e -> NISS -> +2 extension for HTR. So findable but I didnt have time to check all 1HT+qt+NISS.

Also had:
F2 U2 R , F , R2 U' F D B //4b2 4e in 9. 20opt but all sub22 solutions go through 0c0 4e so whatever...

(L2 U2 F) //EO 3/3
(D' L) (D' B2 U' L' U2 * L) //4b2 2e 8/11
L2 F2 U' F2 U' //HTR 5/16
R2 B2 D2 B2 //double slice 4/20
*= U2 L2 R2 D2 R2 L2 //slice 6-4/22
So now we have:
L2 F2 U' F2 U'^ [R2 B2 D2 B2 L R2] D2 R2 L' U B2 D L' D F' U2 L2 //slice in 22
[]=L2 F2 U2^ F2 L' //slice -1/21

Also had:

B' R2 U R' , U (F2 D' F D) //2c4 in 9. 23 opt
And several 2c3 4e in 11 that I didnt really have time to look at.

R (F L' U R') //EO+rzp 4c4e 5/5
(D2 B R2 F B2 U) //4b2 2e 6/11

R2 L2 B2 //wrong slice 3/21
B2 L2 D U' F2 L2 D' U //solved 8-6/23

Also had:

(L^) U2 B2 L B2 D2 R^ //HTR 7/16
U2 D2 L2^ F2 U2 D2 //slice 6/22
^=w
DR is 21 opt but needs 3HTs + 6 move trigger to solve. Hard to check 9 move HTRs on DR where there are many 6-7 move HTRs already...

F' R' F L' //EO 4/4
U' (F' L2 D2 F B2 U) //4b2 4e 7/11

F2] R L' U2 L R' //slice 6/23
[] = B F2 R2 B U2 F //+0/23

Optimal from DR. And seems to be the best you can do without 5 movers so it's fine.
Annoyingly there are many very blocky HTRs in +7 with 2qt but apparently those cant be solved efficiently.

Pretty much the only DR I properly looked at...

Craziest solve ever! HTR skip!

L' B2 L' //EO+rzp 7c8e 3/3

[]= Dw D2 F2 R2 Uw //+1/22

This DR is 21 optimal with 4qt needing 1HT before switch. So findable but can't be mad about missing that...

Also had:

B' D' R' U (L2 F D2 L2 B R) //4c3 in 10, 24 opt

Oh, I missed the 8 move DR: 
D F2 R'                 // eolr       (3/3)
B D'                    // rzpfb-eolr (2/5)

(U2 B' U2 D2 R2 B L2 B ^) //HTR 8/17
(D2 F2 ^ R2 L2) //slice 4/21
^=E2 //+1/22

Also had funny DR:
(F U' R) //EO+rzp 4c4e
D //additional rzp to 0c4e
(D' F D2 U2 B' D) //2c3 2e in 10
That is 21 optimal but the path required 2HTs before reducing to 4b2 4e so quite hard I would say...

(R2 D' B) //EO 3/3
(L) (D B2 R) //2c4 4/7
(U' B2 L2 D' F2 L2 D' R2 D) //HTR 9/16

Wow, a 7 move DR from first EO I checked :D
Finding the finish took a while since it needs 9 move HTR but luckily I had plenty of time.

L2 B' (B' U2 L2 * F L2 B') //HTR 8/18
(R2) //2e2e 1/19

Very similar insertion compared to my last solve :D
Probably easier to see this by doing:
(B') L2 B' R2 B L2 F' //HTR and then direct finish. But whatever works, works.

Also had:
(D' F2 L) (F) L2 U' B2 L2 U F //2c4 in 10

DR opt, but there is a 19 from that rzp if you switch. I switched but couldnt see the +6 to DR. Need to practice more 7c8e...

DR opt.

I had this DR:
(F2 U L F') U2 R2 U2 D2 L B //4b2 in 10 
That is 21 optimal but the path is hard 4qt.

There is also a 20 from that rzp but I didnt see the variation B2 D2 L B2 U2 F. Setups to R2 F2 R are hard, especially since there was a more "normal" DR from that rzp already...

(R' U2 B D' L') //EO+rzp 5/5
(R2 F' R2 U) //2c3 4e 4/9
F U2 R2 * F' U2 B //HTR 6/15
U2 R2 U2 R2 //2e+slice 4/19
*= R2 U2 F2 U2 R2 F2 U2 F2 //slice 8-6/21
Post-DR: F' U2 R2 [F2 U2 F] U2 B U2 R2 U2 R2 
[]= B2 D2 B2 F' //+1/22

Only good DR I had. DR is 21 opt with:
solve -o -t 64 R' U' F R B' L F2 R2 B2 U' F2 U2 R2 D R F' U B2 D F' L2 F' R' U' F (R' U2 B D' L' R2 F' R2)
L2 F' U2 B' D2 F U2 R2 U' D' B2 L2 D

But I dont think I would ever see that finish since post-HTR part involves breaking the already made square and then leaving double slice.

But what I should have seen is trying the extension. That gives an easy 21.

D2 B' F U //EO+rzp 4c2e 4/4

(U L2 U^ F2 D'^) //HTR 5/14
(B2 F2 L2 F2 D2^ L2) //slice 6-1/19
^=w //+0/19

One of the weirdest and funniest solves I have had. Accidentally switch 3c4e rzp and it gives 5 moves to 2c3 4e :D

*= B2 R2 F2 R2 B2 L2 //solved 6-3/22

DR opt.

Mainly looked at these 2 DRs in addition to this one:
(D' B') D (F2 L2 D2 L D2 R' D) //4a2 4e in 10. 23opt.
L2 F' U L , D, L2 F2 D2 B' D //4b2 4e in 10. 22opt.

D2 [R F2 R' U2 R' //HTR 6/14
B2 R2] B2 D2 B2 D2 //slice 6-1/19
[]= Rw' R2 F2 R' U2 Rw' B2 Rw2 //+1/20

This and variations were the only DRs I looked at. Optimal from all of those.

R' F' U L' D //EO+rzp 5/5

optimal from DR.
