Hi! Mind if I take a stab at it?
1. Be3 …, 2. Rxh7 Kxh7, 3 Qh4#.
Only exceptions I see: (1. Be3 Qc4 2. Bxc4; 1. Be3 Qd4 Qxd4)

The obvious move in such problems works just fine 🙂
1. Rxh7+!! Kxh7
2. Qf3!! 1-0
(Black cannot stop a checkmate in a few moves)
1. Be3, threatening
2. Rxh7+ Kxh7
3. Qh4#, as well as
2. Bxc5
1. Rxh7+! Kxh7 2. Be3 1-0 There are two threats for Black to handle simultaneously: 3. Qh4# and 3. Bxc5.
White threatens clearing way for Queen to h4, Rxh7+ and Qh4#
1. Be3….Qc4
2. Bxc4…Nxc4
3. Qxc4…winning the Queen for a piece
If 1….Qd4 2. Bxd4…again winning Queen for piece with all threats remaining
If 1….Nf8 2. Bxc5…again winning Queen for a piece with all threats remaining

Hello.
1. Bd6 Queen moves
2. Rh7+ Kh7
3. Qh4 mates
1, R:h7+ K:h7 2. Bc1 looks tempting, threatening 3. Qh4#, but it looks like black has an adequate defense in 2…g5.
2. Qf3 avoids that defense, e.g. 2…g5 3. Qh5+ Kg7 4. Qg6+ and mate next. 2…g6 is no better, 3. Qh3+ Kg7 4. Qh6#. So it looks like black must play 2…Q:f5 but this looks won for white.
1. Bd6 Qxd6
2. Rxh7+ Kxh7
3. Qh4#
greets, jan
I didn’t really remember this problem (but it is in my files from July 2010), but it is one of the better problems posted here- it requires great precision.
B-d6 threatens Rxh7
Be3 seems good to me. The plan is to play Rh7+ followed by K x h7 (forced) and then Q h4 ++ .. Black needs to give up his queen to prolong the mate but it does not seem to prevent his loss.
correction to previous comment!! after looking at Nf8!! it is better to play Rh7 first followed by Qf3-h5 plan!!!
should lead to win faster!!
Wow. Sorry about the triple post! I thought it wasn’t working
1.Be3 may not be winning for white as SMiNil seems to have found:
1. Be3 Nf8!!
2. Bc5 bc5
And black has two pieces and two pawns for the queen on material balance, but he also has a nearly unassailable pawn structure on the queen side, with the 2nd rank pawn well positioned to tie the white forces down for the long run. It would not surprise me to find this is a draw with best play. I know I don’t see any immediate wins for white, nor can I develop the outlines of even a good plan for a win.
Wouldn’t it just be: Be3 Nf8, Bxc5 Rd1, Be3 b4, be2 Rxe2, Rxa3? I am not using a computer but that seems to work. Those who are can probably tell me the mistake 🙂
Ok. With the initial 1. Rxh7 it works.
1. Rxh7 Kxh7 2. Qf3 g3 3. Qh3+ Kg2 4. Qh6#
As black you could probably defend with 1. Rxh7 Kxh7 2. Qf3 Qxf4 3. Bxf4 Kg1 and that would probably postpone your demise for a while.

What about 1. Be6 ? If 1. … Nf8, then 2. Bxf8.
Practicality,
The line:
1. Be3 Nf8
2. Bc5 Rd1?? is probably a win for for white. I think he can even mate starting with 3.Rh7 now that the a8 rook is unprotected. Even the retreat of 3.Be3 is probably winning now. However, black doesn’t need to help white with that second move. I would just take the bishop at c5:
1. Be3 Nf8
2. Bc5 bc5
As I wrote earlier, I don’t really see a good plan for white to win. I don’t see a good one black either, but that is beside the point. I would really need a long time to evaluate this position, but the weakness of white on the dark squares is going to make very, very difficult to deal with the queen side pawns. A plausible attempt might start with Rd3. There are lines that look possible advantageous for white, but if I were black, I would push 3. …c4, and those lines look not so promising for white. However, I am only thinking about 3-4 moves deep here.
Ein,
I think you are asking about 1.Bd6. However, black can win with c1Q:
1. Bd6?? c1Q!
And now Rxh7 is no threat since the c1Q is set to block any subsequent queen check on the h-file. Let’s take a look at the key lines where white takes the c5 queen to try a deflection:
2. Bc5 Nc5!
Attacks the white queen while retaining the option of replying to 3.Rxh7 Kh7 4.Qh4 with Qh6. White is just down two pieces with almost no compensation.
Also, at move 2, it does white no good to transpose:
2. Rh7 Kh7
3. Bc5 Nc5 and now white is also down a rook in addition to the two pieces with no attack.
@Yancey Ward:
Thanks!
