Any Ideas?

This is a selfmate puzzle.

White, moving first, must force Black to deliver checkmate. Give the sequence of moves that forces Black to mate White on the third move (both White and Black play 3 moves).

Here is the position: lichess.org/analysis/8/1p6/1R6/3pk1bR/3rNpP1/1pQ1pK2/1P2N1P1/8_w_-_-_0_1

No...

This is very tricky...

And please stop asking for help on lichess forum, it is extremely poor sportsmanship and just disrespectful to other contenders in "Advent of Chess".
