RxB
If
1. KxR Nf3+ and the fork takes the rook
If
1. d7+ Kd8
2. Rd4 then White evades the fork but has lost the bishop.

I thought there was an unwritten law in chess that square a1 is down on the left in a diagram. I looked at this diagram quite some time before realising a1 is on top at the right…
Am I correct about the position of a1?
to anon at 10:08:00
after 1 … RxB
2 KxR Nf3+
3 Ke6 NxR
4 Ke7
the pawn queens!
Proper evaluation is required – winning the piece is wrong since after 1…Rxe5? 2. Kxe5 Nf3+ 3. Ke6 Nxd2 4. Ke7 White queens.
After 1…Rf7+ 2. Ke3 (2. Kg3 Ne4+) I can’t quite get 2…Nf3 to work, i.e. 3. d7+ Rxd7 (3…Kd8? 4. Bc7+) 4. Rxd7 Kxd7 5. Kxf3. I’m probably missing knockout somewhere here.
So maybe just the quite line 1…Rf7+ 2. Ke3 Kd7 is required.
My evaluation is that that guy Laffarty is an idiot. Not only that, he is a rude jerk too. He has caused so much divisiveness in the USCF he ought to go back to whatever cave he came out of.
Look further:
RxB
If
1. KxR Nf3+ and the fork takes the rook 2. Ke6 Nxd2 3. Ke7! and White is going to promote.
so…
check on f7 and block the pawn on D6 with the king on d7
You’ve lost your game.
The white king runs to e7 and the white pawn is going to promote.
1…Nh3+ forces the White K away from the B (2. Ke4 Nf2+ wins the R), so 2. Kg3 R:e5 3. K:h3 and black has a much better ending because the pawn on d6 must fall.
1 Rc2+
if 1..Kb6 Nd5+ wins the R
so 1 …Kd6
2 Rc6+ Ke5
3 Rg6
Now white is threatening Nc6+, and Kf4 is met by Nd3 mate.
Re6 is met with nc6+ winning the B or exchange
It seems that white has nothing better than a passive move such as Re8, when black is a pawn up, whites pawns are all vulnerable, as are his pieces and king. This looks like a win to me.

rxb and a fork wins
Do not combine without calculating to the end!
1… Rxe5?? 2. Kxe5 Nf3+ 3. Ke6 Nxd2 and now 4. Ke7! and the d pawn will Queen, so +-
On 1… Nh3+ the white K can go to e4 keeping the bishop safe. However then 2…. Ng4+ forces a draw if black wishes, because the white K must go back to f4 to avoid losing, thus repeating the position. Except black doesn’t have to continue the repetition and can return to the best path instead.
Better than either is:
1… Rf7+! 2. Ke3 Rf3+ 3. Ke2 Kd7 with a slight plus for black, and well worth playing on.
1. …..Rf7
2. Kg3 Ne4 wins, so
1. …..Rf7
2. Ke3 Kd7 (Nf3 3. d7 +-)
and now black threatens Nf3 winning a piece and has control of the open file. Now, white might try exchanging the rooks:
3. Rf2 Rf2
4. Kf2 c5
And it looks to me that the d-pawn will eventually fall
5. Bg7 Nf7 and I like Black’s chances in this endgame.
Anon @ 11:21 — not sure that Nf2+ wins the R, it’s not a fork, so Nf2+, Rxf2.
This is tricky. I like Rf7+ then park the King on d7, and Black has R on open file, d7 pawn blocked and lot’s of cool squares for the active N. Don’t see anything better, but then I’m a weak player!
1… Rxe5 doesn’t really work:
2. Kxe5 Nf3+
3. Ke6 Nxd2
4. Ke7
and Black cannot stop the d pawn from queening.
So:
1. … Rf7+
2. Ke3
(if 2. Kg3, Ne4+ and 3… Nxd2)
2. … Kd7
(if 2…. Nf3 3. d7+ Kd8 4. Bc7+)
Now, 3. c5 Nf3 wins for black.
or 3. Rf2 Rxf2 4. Kxf2 Nf7 and white d-pawn falls.
or 3. Rd3 Rf3+ has the same effect (exchange rooks and the d-pawn falls)
3. Rd1 Rf3+
4. Ke2 Rxb3
is this good for black?
it’s hard for the white rook to get to the 7th rank. the f7 square is controlled by the knight. black rook is holding on to the b-file.
the d-pawn is weak. if white manages to protect it with c5, then the c-pawn and the a-pawn are both weak.
1…Rxe5? 2.Kxe5 Nf3+ 3.Ke6 Nxd2 4.Ke7 white wins !
1…Rf7+ 2.Ke3 Nf3? 3.d7+ white wins!
so I think the best is 1…Rf7+ 2.Ke3 and now 2…Kd7 or 2…Rf3+ 3.Ke2 Kd7 ,
if Blank wants draw, he can play 1…Nh3+ 2.Ke4 Ng5+
