Optimal from DR. I found the HTR in 18 but then inserted the 2e2e straightaway. Then I worked on some stuff that was longer and found a sort of slicable 25, but yeah, completely useless. Mallard finds no 20, so I'm very pleased. After finding the 21 at 35, I just spammed all the remaining EOs I had.

In this attempt, I went too safe. I found another 24 from a 12+0 (optimal) and then I dived into the 3 variations of this 10+4.
Sadly, two variations are 21 optimal, findable but they pass through an HTR that reduces to 4b2 4e.
Probably I would have tried more HTRs if I had just gone a little harder. Two 24s don't make a 23. Mallard finds a easy 21 from eo in 4 (super chill 12+2, missed rzp obviously) and 20 from niss eo in 5.

Found a 24 from another 12+0 lol, that almost matematically gave me the win (I had a 11 move lead at this point) at 22 minutes and then this at 40. This is obviously optimal from DR and Mallard finds at best 21 but from some obscure DRs in 12. The 12+0 was 23 opt (but it doesn't matter cause it was not final solution).
