Wish I could ignore the black queen, but it does cover h6. So, I am thinking Rg6 here:1. Rg6 Re7The only really different defense looks much worse to me: [1. ...Rg8 2.Rf8 a1Q 3.Qa1 Kh7 4.Rc8 and black must lose a rook overall and I don't see a way to keep the pawn from queening either]. Continuing:2. Qe7 Qc3 (Rg8 3.Rg7! Rg7 4.Rf8)3. Ra6I see nothing better. I can argue that 3.Rd6 is nearly as good, but Ra6 is clearer to me- it wins the a-pawn outright with no complications since black must deal with the mate threat that starts with with Rf8+. Continuing:3. .....Kh74. Ra2 d2 (what else?)5. Rd1 and the d-pawn will fall too. Game over.Now, if 1.Rg6 the best move? I don't know. I got that nagging feeling I am overlooking something much more forcing in this position.
Not positive, but maybe something like...Rf8+ Rxf8exf8=Q Rxf8Re8Then the black rook is pinned, and if ...Rxe8, Qxe8+ and white has a simple perpetual.
Ah, I just checked it and that doesn't work at all.
Well, White plays 1. Rg6 seems a good move.If 1.... Rg8; 2.Rg8 winsIf 1.... Qc3; 2.Rh6 Kg8 3.Qe6
I guess my comment didn't go through. My idea was:Rf8+ Rxf8exf8=Q+ Rxf8Re8That pins the black rook, and if ...Rxe8, Qxe8 starts a perpetual. Unfortunately, black is just winning after ...Qf2.
1) f8, rxf82) pxf8+, rxf83) e8, f8xe84) then white has perpetual check
Is the idea for W to get one more piece on f-file to check on f8?eg 1.Re6-f6if 1....gxf6 2.Rxf6+(!)withdiscovered check(s)if say 1....Qc3 2.Rf8+ Rxf83.Rxf8+ Rxf8 4.exf8(Q)+W has check on white squares.if 1....Rxe7 2.Rf8+ Rxf83.Rxf8+ Kh7 4.Qf5+ g65.Rf7+ Rxf7 6.Qxf7+ draws0-0-0-0-0-
1. Rg6 threatening 2. Qxg7++The most logical for Black (really forced) is 1. . . Rg82. Re8 again threatening 3. Qxg7++2. . . R(c)xe8 3. dxe8(Q) with no way for Black to prevent mate. . . Qxg2+ only delays the inevitable, with the loss of the Black Queen.
R(e)f6 sure looks strong it appears to be winning
1. Rg6 leads to a forced mate. 1. Ref6 also wins, but more slowly. 1. Rg6 Rg8 2. Rxg7 Rxg7 (2. .. a1=Q 3. Rh7+ Kxh7 4. Rf7+ Rg7 5. Qf5+ Kg8 (5. .. Kh8 6. Qxc8+ Kh7 7. Qf5+ Kh8 8. e8=Q+ Rg8 9. Rh7#) 6. Rf8+ Rxf8 7. exf8=Q#)3. Rf8+ Kh7(3. .. Rxf8 4. exf8=Q+ Kh7 5. Qfxg7#) 4. Qe4+ Rg6 5. Rf7+ Kh8 6. Qe5+ Kg8 7. e8=Q+ Rxe8 8. Qxe8#1. Ref6 Qg5 (1. .. gxf6 2. Rxf6 Kg8 3. Rg6+ Kf7 4. Qe6#) (1. .. Rxe7 2. Qxe7 Rg8 3. Rf8 Qe2 4. Rxg8+ Kxg8 5. Qf7+ Kh8 6. Qf8+ Kh7 7. Qf5+ Kg8 8. Ra1) 2. Rf8+ Rxf8 3. exf8=Q+ Rxf8 4. Rxf8+ Kh7 5. Qe8)
