Well, this went to Rochade Europa.
I got the email from this site:
http://www.goja.szm.sk/p5a.htm
And sent it for publishing.
By the way I believe there is a tourney coming for John Nunn's 50-th jubilee:
http://www.goja.szm.sk/p9a.htm#Nunn
I've also published another study in Probleemblad but apparently there was a mess up with the mails so in result it got also published in Schach magazine and was disqualified from both 🙁.

I thought it might be 1. Rxb4, but I can't see anything better than a draw. Little help here?

Allow me to recommend StrateGems, the US Chess Problem magazine. Their section editors are all listed on this page: http://www.strategems.org/contact.htm

This is certainly going in the right direction 🙂 And what follows 2...Qxb5!?

How about an approach maneuver with the queen?

1.Ra3+ bxa3 2.Qf7 Qxb5 3.b4+ Ka2 4.Qxf7+ Ka1 5.Qf6+ Ka2 6.Qe6+ Ka1 (other moves run mate) 7.Qe4! (blocks all black's checksquares) Nd2 (only move) 8.Qd4+ Ka2 9.Qxd2+ Kb3 (otherwise mate in few moves) 10.Qc2+ Ka5 (or Kc5 or Kc4) 11.QxQ KxQ 12.g5! with a won endgame. The black king has to defend the kingside, white will play f5 (gxf loses the race to queen, and if a2 then simply Kb2) and f6 and then grab the a- and c-pawn before going to the kinside to finish the game.

Nice!

Well done Mephisto. Just one clarification I believe you have missed a move (namely 11.Qb1)
10.Qc2+ Kxb4 11.Qb1+ Ka5 and 12.QxQ KxQ 13.g5! Kc6 14.f5 Kd6 15.Kb1 Kd7 16.Ka2 Kd6 17.Kxa3 Kd7 18.Kb4 Kd6 19.Kc4 Kd7 20.Kc5 c6 21.f7! Ke7 22. Kxc6 Kxf7 23.Kd7! and wins.

1.Ra3+ bxa3 2.Qg7 Qxb5 3.b3+? loses because black hides behind the white pawn with Ka2 e.g. 4.Qxg7 Qxb3 wins. The move 4.b4+ is necessary for white to have two consecutive checks.

And I suppose if
1. Ra3+ bxa3
2. Qg7 Qg2
then
3. bxa3+ Ka2
4. Qxf7+ Kxa3
5. Qe7+ Kb3
6. Qe6+ Kb4
7. Qc4+ Ka5
8. Qxf1 Qxg4



Although this looks like a technical win, it is by no means straightforward.

I believe after 9.Bc6! (10.Qb5# ) all goes relatively easy.9...Qf(h)5 10.Qc4 and White wins; 9...Kb6 10.Qb5+ and 11.Qb7#;9...Kb4 10.Qb5+ Kc3 (10...Ka3 11.Qb2# ) 11.Qc5+ Kd3 (11...Kb312.Bd5+ Ka4 13.Qc4+ Ka5 14.Bc6 + -) 12.Bb5+ Ke4 13.Qe5+ Kf3 14.Be2 + wining the queen.
