Good luck, and have fun solving!

Wow

honestly you can win in many ways, this just tests your skill on finding the fastest way to win which can help with tactical vision

If it’s red to move then I believe Rxm10+ mates

1. Rxm10+! (Any blue move) Rj10 Nxm10

2. Ri10 (blue move) Rxm10+ Kn11 

and yellows next move Rn10+ is just crushing

dude it literally says yellow to move in the title smh

I don't have time rn, but both Rj10 and Rj11 look promising. Rj10 really funny so I'd probably play that (idea is that yellow takes m10 next, and we try to capture green's kind, although blue might be able to interfere

Rj11 is objectively better. Rj10 doesn't work as well because of l10 by green.

Good point, also blue has Re5 which prevents ry from doing any Rxn4 and RxI10+ things. Rj11 is safer, although I think bg are okay after Rxi4+ Nxf4 Re5, although they are down a piece and will eventually lose.

... Re5 Bf3+ and ry win the blue rook
