White to move. How should white proceed?

1. Rf3 g2 2. Bf1 g1Q 3. Rh3#
or. 1. Rf3 Kg2 2. Rf8 and then Bf1 1:0
Okay, I got!
1.Rf3! g2
2.Bf1! wining
2…g1Q loses to Rh3#
In my opinion the move would be r-f1 to r-f3 then if p-g2 B-F8! followed by R-h6 mate if the pawn queens or simply exchanging the bishop for the pawn if the pawn does not move or takes the bishop.

1 Rf3 ( only move ) g2 ; 2 Bf1 wins
A draw offer would seem to be appropriate.
On second thought though, 1. Rf3 g2 2. Bf1 g1=Q 3. Rh3# wins, so… don’t offer that draw
Very, very pretty puzzle.
Obviously, black is threatening to get a queen at g1 supported by her king. The white bishop cannot cover the g2 square because it’s access to the square is cut off by both the rook and the king. And, sacrificing the rook at g1 simply leads to a draw by insufficient material. However, there is a really neat trick for clearing the way for the bishop:
1. Rf3!
And, now, black has g2, and the four kings moves. 1. …Kh3 allows 2.Bf1+, and the bishop, protected by the rook on the f-file will take the pawn whenever it is moved, giving white time to bring the king in for the kill. 1. …Kg2 is met by 2.Rf5 followed by Bf1, and, of course, 1. …Kh1/g1 just lose the pawn immediately to 2.Rg3. This leave the pawn push:
1. …..g2
2. Bf1!
Told you it was pretty. Now, if black plays 2. …g1(Q,R,or B), white mates with 3.Rh3, and the two king moves just lose the pawn for the bishop, as does gf1(Q). This leaves only the underpromotion to a knight to cover h3:
2. …..g1(N)
3. Re3 and, eventually, black is going to get mated near the corner since the knight has no moves to a square that it isn’t immediately captured. White can just bring the king forward to cover f3 from e4, then move the rook to e1, then bring the king to g3 via f4, and delivers mate with either a discovered check, or with a double check.
1. Rf3! g2
2. Bf1
2. … g1=Q 3. Rh3#
2. … gxf1=Q 3. Rxf1 +-
Other first Black moves allow Bf1 in time to stop the pawn, e.g.
1. … Kg4
2. Rf8 g2
3. Bf1! g1=Q
4. Rg8+ and 5.Rxg1
1.rf3 g2 2. Bf1 +-
1. Rf3 g2
2. Bf1 g1Q
3. Rf3++
ot
2. … g1N
3. Rf2+ wins the Knight, after 3….Kg3 4. Rg2+ or 3….Kh1 4. K moves.
1. Ra1 g2 (or another move)
2. Bf1 g1=q
3. Ra2+ Kg3
4. Rg2+ and queen is gone
1: Ra1 g2
2: Bf1 g1Q
3: Ra2+ Kg3
4: Rg2+ Kh4
5: Rxg1
Quorthon
1.Rf3 and 2.Bf1
1.Rf3 looks promising, with the idea of 1…g2 2.Bf1 g1=Q 3.Rh3#. Phil
1.Rf3 threatening to trade off the bishop for the pawn with 2.Bf1,
1…g2
2.Bf1 (anyway)
2….g1(Q)
3.Rh3 mate
OR
2….g1(N)
3.Rf2 and the night is toast.
1. Rf3 g2 (the only move) 2. Bf1! g1=Q (2… g1=N 3. Rf2) 3. Rh3#
Anonymous 1:32:00 PM Your line leads to a draw not a win for white.
The trick is giving up the bishop on f1 while preserving the rook.
Rf3 Kg2 Be2 now the black king has to step back Kh2 Bf1 and either the king gives up contact with the pawn or else g2 and Bxg2 winning
1. Rf3 g2
2. Bf1 g1(Q)
3. Rh3#
or
1. Rf3 g2
2. Bf1 Kg1 or Kh1
3. Bxg2 wins
or
1. Rf3 Kg2
2. Be2 Kg1 (or Kh1 or Kh2)
3. Bf1
and white can sac the bishop for the pawn and win
or
1. Rf3 Kh3
2. Bf1+ Kg4
3. Bg2 wins

Anonymous commenter at 1:32 PM CDT,
It isn’t stated explicitly, but it is white to move and win. White can just let the pawn queen and draw with the rook and bishop vs the queen. Your line only draws:
1. Ra1 g2 (else, Bf1 wins)
2. Bf1 g1(Q)
3. Ra2 Kg3
4. Rg2 Qg2 =
1. Rf3 g2 2. Bf1 g1=Q 3. Rg3#
1.Rf3-g2
2.Bf1!
Proka
Ha! I think I finally got one!
Rf3! is the move. If g2 then Bf1 and the pawn cant queen because of Rh3!
ah.. Rf3 g2, bf1! g1Q, Rh3# nice. huitag
i think, the move Rf3 wins:
1. Rf3 g2
2. Bf1 g1Q
3. Rh3#
2. … gxf1Q
3. Rxf1
1. … Kg2
2. Rf8 Kh2
3. Bf1
greets, jan
Rf3
this was a process of elimination,every other moves draw and i considered greatly it had to be a R move if Be2 then g2 Rg3 Kg3= so it had to be a r move. Ra1 was my first move i considered. after i saw g2 ra2 and i thought of kh1 Be2 g1 Bf3 and winning but Kg3 is a draw so the last idea i saw was rf3.
1…g2
2.Bf1!! this is the point! white plays Rf3 to enable this move. white will soon win.
2…gxf1
3.rxf1 black is hopeless.
