The solution that I came up with is: b7+ , Ka7 Ra1+, Kb6 Nc4+! forking the K and R. I think that is the best that white can do as it mate on the move if white does not check in each move.
Ra1+ and if Black interposes his R, Ra7+ followed soon by b7 mate. If Black interposes either or both Knights to the original Rook check, he will be back-rank mated in a hurry.

Anyone disagree I would love to hear it.
Looks quite easy: 1. Ra1+ Ra2 2. R7a7+ Rxa7 3. b7#
this is my try:
1.Ra1+ Ra2 2.Ra7+ Nxa7 3.b7 checkmate
Looks quite easy: 1. Ra1+ Ra2 2. R7a7+ Rxa7 3. b7#
1. Ra1 Ra2
2. Ra7! Na7
3. b7#
If 2. . . . Ra7, then 3. Ra7 and 4. b7.
1. Ra1+ Ra2
2. Ra7+ Rxa7
3. R/Nxa7+ b7#
1. Ra1+ Ra2 2. Ra7+ R:a7 3. R:a7+ N:a7 4. b7#
1.Ra1+ Ba3 2.Ra3+ Na6 3.Ra6+ Na7 4.Rg8# is the best sequence…
an easy one…
…Rh8+
Rh7 Rh2+
Rxh2 g2#
1. Ra1 Ra2
2. Ra7 Ra7
3. Na7 b7 #
1. .. Na6
2. Ra6 Kb8
3. Rg8
1.Ra7+! Nxa7 2.b7 mate!
Kamalakanta
It’s a forced mate for white!
1. Ta1+ Ta2
2. Ta7+ Txa7
3. Txa7+ Nxa7
4. b7#
Delightful.
1 Ra1
If 1.. Ba3 2 ra3 na6 3 Ra6 kb8 4 rb7#
The main line is 1…Ra2 2 Ra7! Ra7
3 Ra7 na7 4 b7#.
1. Ra1 Ra2 (..Na6 2 RxN+ Kb8 3 Rg8+ and mate follows)
2. Ra7 NxR
3. b7++
1.Ra1+ Ra2 2.Ra7+ Rxa7 3.Rxa7+ Nxa7 4.b7#
How’s about:
1. Ra1+ Ra2
2. Ra7+ Rxa7 (or Nxa7)
3. b7#
Ra1+Ra2,Ra7Nc7(..Rc7,Ra7Nc7) and
a7#
So simple I am sure I am wrong- it seems a pretty smothered mate motif:
1. Ra1 Ra2 (only effective move)
2. Ra7 Ra7
3. Ra7 Na7
4. b7#
The key is to deflect the b-rook to the a-file. It’s presence on the b-file makes an immediate Ra7 ineffective.
Ra1- Ra2,Ra7- R:a7,R:a7- N:a7,b7X.
Ra1+ and if Black interposes his R, Ra7+ followed soon by b7 mate. If Black interposes either or both Knights to the original Rook check, he will be back-rank mated in a hurry.
oops,
ra1+ first before my prev comment.
h
this is the solution..
ta1+ , ta2
ta7+ , ta7
b7++
1. b7+ immediately fails to Rxb7.
The main line (not counting temporary diversions) looks like
1. Ra1+ Ra2, 2. Ra7+ Nxa7, 3. b7++. Phil
b7+ ?
Ra7+ and then b7++
1. Ra7 Nxa7
2. b7# mate
That was wrong, lol. I should’ve studied the position much further :).
1. Ra1+ Na6?
2. Rg8+ Nc6-b8
3. Rxa6# mate
1. Ra1+ Ra2
2. Rg7-a7+! Nxa7 (or Rxa7)
3. b7# mate
Ra1+ pretty much does it.
