This was an actual game. It is White to move. How do you assess this position? Is this a draw, win for White or win for Black? What is the best way for White to proceed?

White can mate starting with Qd6+. Black must interpose the rook or is quickly mated. Then white follows up with Qb8+, to which black must respond with Ke7, and then white’s b5+ forces black king to f6, so white queen gives a check on f8 and the rook is forced to interpose again, and whites bishop gives a decisive check on e7. Black is forced to capture the other bishop on f5, and white queen mates by capturing the rook on f7.
move queen to h8, king moves to e7,
move pawn for discovered check, move queen to square protected by black bishop, i guess
move queen to h8, king moves to e7, discovered cheque by moving pawn, moving queen to bishop protected square i guess
Qh8+ Ke7
b5+ Kf7

Qh8+ Ke7
b5+ Kf7

1. Qd6+ Rd7 (Ke8 2. Bg6#) 2. Qb8+ Ke7 3. b5+ Kf6 (Kf7 4. Qf8#) 4. Qf8+ Rf7 5. Be7+! Kxf5 6. Qxf7#
White wins! 😀 fascinating mating pattern, too.
Hope I didn’t miss anything.
White wins! The trick is to continually check the black king.
1. Qh8+ Be8
(If 1…Ke7 then 2. b5+ Kf7 3. Qf8#)
2. Qf6+ Re7
3. Qd6+ Rd7
(If 2…Bd7 then 3. Qb8 Bc8 4. Qxc8#)
4. Qb8+ Ke7
5. b5+ Kf7
6. Be6+ Kxe6
7. Qxe8+ Kf6
(If 7…Kd5 then 8. Qe5+ Kc4 9. Qc5#)
8. Qe5+
Eventually white’s queen and bishop can corner the black king.
Oh, also:
if 3. … Rd6 then 4. Qxd6+ and the king gets mated whichever way he goes.
Need something better. We never get the answers. Perhaps if you post them top to bottom in a bloc with last weeks answer for reference. BTW great job with the face book and news!
White wins with Qh8+. If blocks with the bishop, Qh4++. If moves the king, push the b pawn with check, mate soon.

white is in zug. I was wishing forces mate but is not possible in this variation, white loses if try it. I will try a draw, let’s see if I can find.
white advantage if you played check with the white queen on the d file I think.
Win for white
1 Qd6+ Bd7
2 Qf8+ Be8
3 Qf6+ Re7
4 Qd6+ Bd7
5 Qb8+ wins
1 … Rd7
2 Qb8+ Ke7
3 b5+ Kf6
4 Qf8+ Rf7
5 Be7+ Kxf5
6 Qxf7#
1. Qd6+
should either win or draw
1. … Rd7 loses for Black
1. … Ke8 2. Qe6+ gets perpetual at least.
White to move Qh8+
1. Qh8+ (1…Be8 2. Qf6+ Re7 3. Qb8 #) (1…Kd7 2. b5+ Kf7 3. Qf8#)
1. Qh8+ (1…Be8 2. Qf6+ Re7 3. Qb8 #) (1…Kd7 2. b5+ Kf7 3. Qf8#)
1. ♕h8+ ♚e7
2. b5+ ♚f7
3. ♕f8#
White checks with Qh8+, black can either move his King to e7 or place his Bishop on e8. White plays Qf6+ if Be8, Black can only play Re7, White plays Qd6+ black can play Bd7 or Rd7 where white responds with Qb8+ for both cases and wins.
If black plays Ke7 after Qh8+ white plays b5+ and after black playing Kf7 then Qf8#
1.Qh8+ Ke7 2.b5+ Kf7 3.Qf8# looks fine.
Sorry, Susan, about variation B) after 6. …Qg3+ the best move here is 7.Kxe4 instead of Kd4?? (I analuzed first Qf3+ for this reason I forget – no use computer help neither board help- e pawn was not protected after …Qxg3+) and is equal position, sorry! After 7.Kxe4 the position is going to drawn!
But verifying again (with board help) I see that 6.Be6+ (I had not considered so good yesterday night) is better than takes imediatelly on d7. I was look out to 6. … Kg7 (after Be6+) but simply Qe5+ the white treats the black king!!!
So
6.Be6+ Kxe6
7.Qxe8+ Kf6
8.Qe5+
either 8. …Kf7 or 8. …Kg6
white get the rook on d7 with 9.Qf5+ or Qe6+
My conclusion now is that white wins!
A White win is not clear.
1. Qh8+ Be8
2. Qf6+ Re7
3. Qd6+ Rd7
4. Qb8+ Ke7
5. b5+ Kf7
and whether White plays Bxd7 or Be6+, Black begins to check the exposed White King with his Queen and the outcome is in question.
It’s amazing how many easy wins for white people have found here.
The problem is they all assume black moves that are not enforced.
The only enforced looking line is the one that Pranav Dandekar and Mr. Costa have analyzed starting with:
1. Qh8+ Be8
2. Qf6+ Re7
3. Qd6+ Rd7
4. Qb8+ Ke7
5. b5+ Kf7
I think Dandekar’s suggestion looks interesting:
6. Be6+ Kxe6
7. Qxe8+ Kf6
8. Qe5+
though I’m not sure I see the outcome clearly….
Oh, I think I see an improvement on Pranav Dandekar’s line:
1. Qh8+ Be8
2. Qf6+ Re7
3. Qd6+ Rd7
4. Qb8+ Ke7
5. b5+ Kf7
6. Be6+(!) Kxe6
7. Qxe8+ Kf6
8. Bb2+!
The improvement, better than Qe5+ I think.
Either black replies with Kf5 or Kg7, white takes rook on d7 with check, and now the win seems easy.
Forget it.
I missed Qxb2.
Well, let’s follow the sequence of my last analyses (this is the 3th post). I simply conclude my analyses saying after 8. … (move black king) the white wins a rook and the game. But after my post someone posted at the and of white checks, black has a perpetuo! Well, let’s see what happens after white takes on d7:
A)
8. …Kf7
9.Qf5+ Kg8 (…Ke8; 10.Qf8 mate, King moves to g8 to avoid white king takes on d7 giving check)
10.Qxd7 Qf3+
11.Kd2 here, if black takes bishop on a3, then white wins after 12.Qc8+ Kf7 ; 13.Qxb7+ Kf8; 14.Qc8+ Kf7 15.Qf5+ if king moves on e-file then queen takes e-pawn, if moves on g-file, queen takes g-pawn.
Let’s try a perpetual by black queen
11. …Qf2+
12.Kc1 Qe1+
13.Qd1 Qc3+
14.Kb1 Qxa3
15.Qxg4+ Kh7
16.Qf5+ Kh6 (Kh8 17.Qc8+ followed by Qxb7)
17.Qf6+ Kh7
18.Qf7+ Kh6
19.Qe6+ Kg7
20.Qxe4 and advantage white
or
12. …e3
13.Qxg4+ followed by Qe2 and white wins!
Ah…. sorry,

8. …Kg6
