rxb11 g moves king , rxc9 , kxb11, d11
Teams puzzle #141 [Yellow to move]

I know the answer, checkmate guarantee,
start from yellow
Rxb9, Kn8, Bb10+, Rxb10, Ra9+, Kn7, Rg11+ #
How if the red doesn't take the B, but move King to a10
I didn't found the best move after that, because green can attack red by his Knight

Hmm, I think I found it, the key is too keep the yRook on the board, because have officer/piece (idk the english word for this) at both side is powerful, so we need to check blue by rBishop,
Start from yellow
Rxc10, Kn8, Bb10+
we have 2 option for blue,
1) blueRxb10, redRxb10, Nl5, Rg10, Nd11, R10, Nxk3, Ki1 ... After this move, ry have good position (far from check at red and easy to avoid at yellow)
2) blueKa10, Rn10+, Bxc9+, its done whereever King red moves

Rxc10 Km8 Bb10+ Rxb10 Rxb10 Nl5 Rg10 Ra10 Rxa10+ Nxk3+ Ki1! Nxa10
f+g+h pawns will decide the game
then yellow might as well take on b11

Rxc10 Km8 Bb10+ Rxb10 Rxb10 Nl5 Rg10 Ra10 Rxa10+ Nxk3+ Ki1! Nxa10
f+g+h pawns will decide the game
Great job, however I am not sure that ending is completely winning, when I played it against myself I could stop the pawns with the two knights. If it is winning though, you have found a second solution.
