That's part of it (although your move 2 should have read: Kf1 Rd1+).
But on white's response on move 3 could be:
3. Ke2 Rd2+
4. Kf1 e2+
Kxf2 e1=Q#
But this other line:
4. Qxd2 exd2+
Kxd2 Bc8
Just seems like a RBB vs RN (or BR vs R) endgame. Messy.
4. Qxd2 exd2+
Kxf2 Be4
Ke3 Bxf5+
Kxd2 Rd8+
Kc3 Rc8+
Kany Bxc2
Is a little neater with a RB vs R.
Maybe I missed something...
Ah, forget it ilywrin already solved it with a reversal of moves which completely eliminates the white King's choices (here it is for clarity's sake):
1. .. Rd1+
Rxd1 Bf2+
Rf1 e2+
Kxf2 exd1=N+
Kany Nxc3

ilywrin got it right:
1...Rd1+ 2.Rxd1 Bf2+ 3.Kf1 e2+ Kxf2 exd1N+ and an easy black win
In the actual game, Roth-Baumgarten 1959, the play went
1...Bf2+ 2.Kf1 Rd1+ 3.Ke2 Rd2+ 4.Qxd2+ exd2+ 5.Kxf2 Bf3 6.Nd6 Rf8 and white resigned

Black has a clearly won position already, but how do you finish off white most effectively?
Black to move.

1. Rxf2?
If 1. Rxf2 2. Ng3+ Kg1 3. Nxe4 and black is up 3 pawns and dominant position.
If 1. Bxb7 2.Rxf1+ Qxf1 3. Ng3+ Kg1 4. Nxf1 Bxa8 and black is up a queen to a rook.

That would lead to fxg3, Rxf1+ Rxf1.
So both sides lose a B and R and white loses an additional N.

I'm thinking:
Ng3+ fxg3
Rxf1+ Qxf1
Bxe4
Both sides lose a R and a minor piece and we ruin black's King-side pawn structure.

How about...
1...Bxe4
2. Qxe4 Rxf2
3. Rxf2 Ng3+ winning queen and bishop for rook and bishop.
Or if 3. Qd3 (for example), then ...Rxf1 4. Rxf1 Ng3+ winning two rooks and a bishop for bishop and knight.

I wouldn't call this a 'simple tactical exercise'. Nice one though

After the first Rxf2 white can play Qxa8+ winning both rooks after Kf7 Rxf7+.

Very well spotted, Josh.
I know this one was tough, but I thought it was a very
beautiful and somewhat unusual checkmate.

White to move
1. Qb5+ Qxb5
2. Nf6#
1. .. Nd7
2. Qxb6 axb6 (.. Nxb6, Nf6# ) (edit: dumb googly face)
3. Re1
1. .. Rd7
2. Qxb6 axb6
3. Nf6+ Kd8
4. Nxd7 Kxd7
Which wins the exchange in addition to doubling black's queenside pawns.
