White to move. How should White proceed?
8/2p2k2/1p1p1P1R/3Pr1P1/p2b2B1/P7/2K1p3/8 w – – 0 1
I see three main lines:
1. Be6 Re6 (Ke8/f8?? 2. Rh8#)
2. de6 Ke6
3. Kd2 Bb2 and black might have at least a draw, I think, though this line needs more analysis than I have given it.
Line 2
1. Bh5 Kg8 (Kf8?? 2. Rh8#)
2. Rg6 Kf8
3. Rh6 Kg8 is a draw. 2. f7 doens’t seem to lead to anything better, either.
Line 3
1. Rh7 Kg8 (Kg6?? 2. Rg7#)
2. g6 e1(Q)
3. f7 Kf8
4. Rh8 Ke7 (Kg7 is no better)
5. f8(Q)#
Be6+
Rh7+
if Ke8 or Kf8, Be6
if Kg6 Rg7++
if Kg8 g6 followed by Be6 or f7+
1.Bh5!+ Kg8 forced 2. f7+ Kg7 3. Rh7+!! KxR 4.F8Q e1 Q 5.Qh7+ +-
1. Bh6+ Kg8
(if 1… Kf8, 2. Rh8#)
2. f7+ Kg7
3. Rh8 Kxh8
(or 3… e1(N)+ 4. Kd1, Kxh8 with similar outcome as the main line)
4. f8(Q)+ Kh7
5. Qf7+ Kh8
6. Bg6 e1(N)+
7. Kd1
1-0
Be6+ does the trick

I don’t think Be6 works – Rxe6 and then black queens his pawn.
Rh7 is interesting, but I think Bh5 is the best. Mating possiblities without the chance of the rook just exchanging for the bishop. Stuff like Bh5+ Kg8 f7+ … I’m not sure what happens if black gets a move and promotes to a knight to call check, though 🙂
Rh7+ (my initial choice) probably still wins but is inaccurate. Be6+ is more to the point.
Hello
1. Bh5+ , Kg8 ( if Kf8, 2. Rh8++ )
2. f7+ , Kg7 ( if Kf8 3. Rh8+ and f8=Q winning )
3. Rh8!! winning
if Kxh8, 4. f8=Q+, Kh7 5. g6++
and whith other movement f8=Q++.

“Rh7+ (my initial choice) probably still wins but is inaccurate. Be6+ is more to the point.”
Inaccurate is a rather polite way of putting it.
Both are inaccurate 🙂 Wanna phone a friend?
How about:
1. Bh5 Kg8 (forced)
2. f7 Kg7
3. Rh8 Rf5 (no time for e1(Q)
4. Rg8#
bh5
Bh5+
1. Be6 doesn’t win outright because of 1… Rxe6.
1. Rh7 doesn’t win outright because of 1… Kg8 and then the continuations are not really the solution to the problem.
1. Bh5+!! wins easily. 1… Kg8 2. f7+ has a mate in a few moves.

I’d go for:
1 Bh5+ Kg8 (1 .. Kf8 2 Rh8#)
2 f7+ Kg7
3 Rh8! (threatens both Rg8# and f8=Q#, and 3 .. e1=N+ 4 Kd1 does not help)
3 .. Kxh8
4 f8=Q+ Kh7
5 g6#
1. Bh5+ Kg8 (Kf8 leads to Rh8#)
2. g6 e1/Q (for example)
3. f7+ Kg7
4. Rh7+ Kf8
5. g7+ Ke7
6. f8/Q+ Kd7
7. g8/Q disc ch Re7
8. Bg4+ Qe6
9. Qg8xQ#
I think that’s right. Very entertaining. Does Black have a better 2nd move than e1/Q?

seems like the only good choice is to start with Bh5+ then push f pawn:
1 Bh5+ Kg8
(…Kf8, Rh8#)
2 f7+ Kg7
3 Rh7+ Kxh7
(3… Kf8, 4 Rh8+ Ke7, 5 f8=Q+ Kd7, 6 Rh7+ Re7 etc.)
4 f8=Q
here i think black’s trickiest move is 4 … e1=N+ but white simply parks on d1. so:
4 … Rxg5 ( to prevent g6#) is met by
5 Qf7+ Kh6
6 Bxe2
and maybe black could try …Rg2 then white can go for stuff like 7 Qf4+ picking up the d4 bishop…or even the rook as i don’t think a fork can be avoided:
7 … Kg6
8 Qe4+
if:
7 …Kg7
8 Qxd4+ etc.
that’s as far as i got. i don’t think 4 … e1=Q helps black but it might force white to draw through perpetuals. not sure
Bh5+ Kg8
f7+ Kg7
Rh8
and queening can’t be stopped!
B h5 and black is done.
