Td7+ Ka6 2. Qxa7 + Kb5 f4+ Qc7 ++
1 Rh5 dis. ch, Rc6
2 Rxh7+
Rd7+ Ka6
Qb7+ Ka5
b4+ Kb5
Qd5+ Ka6
b4+ Ka5
Rxa7
1. Rd7+ Ka6 (forced)
2. Qb7+ Kb5 (or Ka5)
Combination of white pawns + Queen should mate the black King.
I was thinking about this line
1.Rd7++ Ka6 2.Qb7+ Kb5 3.c4+ Qxc4 4.bxc4+ Kxc4 5.Qd5#
I can’t see an escape for black. The double check seems to be decisive.
Best Regards

Rd7+
Rd7 dis check! then mate in 3 moves.
1Rd7++ ka6,2Qb7+ followed by rapid mate after white check with either a or b pawn.
1.Rd7 Double+,Kc8.
2.Qb7 #
1.Rd7 Double+,Kc8.
2.Qb7 #
1.Rd7+ Ka6 2.Qb7+ Ka5(Kb5) 3.Qd5+ Ka6 4.Qc4+ Ka5 5.Qa4#
The best move would be;
1. Rd7++ Ka6
2. Qb7+.
option 1;
2….Ka6
3. b4+ Kb5
4.Qd5+ mate
option 2;
2. …..Kb5
3. a4+ leads to mate or loss of officials and eventual mate.
Im thinking like that:
1. Rd7++ Ka6 (only)
2. Qb7+
2. … Ka5
3. b4+ Kb5 (3.. Ka4 4. Qa6x)
4. Qd5+ Ka4 (4..Ka6 5. b6+ Ka5 6. Ra7x)
5. Ra7x
2. … Kb5
3. a4+ Kc5 (3..Kb4 4.c3+ Ka5 5.Qa7x)
4. Qd5+ b4
5. c3x
i think in this exercise very important is place d5 where in begining is Rook then she go d7 coverd place for Queen witch is not atack by black rook d8. niece.
if i made mistake please corect me it is only my imagination.
Rd7 double check !!
1.Rd7+
If 1… Kc8 or Kb8 2.Qb7++
If 1… Ka6 2.Qb7+
If 2… Ka5 3.Qxa6+ Kb5 4.Qa4++
If 2… Kb5 3.c4+ Kc5 4.Qd4++
1. Rd7
The best move is Rd7+ The end for black
1.Rd7+
If 1… Kc8 or Kb8 2.Qb7++
If 1… Ka6 2.Qb7+
If 2… Ka5 3.Qxa6+ Kb5 4.Qa4++
If 2… Kb5 3.c4+ Kc5 4.Qd4++
1.Rd7++ Ka6
2.Qb7+
Rd7
Rd7
The black King has to go to a6 and into a mating net.
1.Rd7++ Ka6 2.Qb7+
I)2….Ka5 3.b4+
II) 2….Kb5 3.a4+
and in both cases the black king soon gets mated
1.Rd7+ Ka6, 2.Qb7+ Kb5 3.c4+ Ka5, 4.Qxa7+
Dear Susan, do you know why women world champion Miss Yifan does not have any rating? Thank you. Here is the website: http://ratings.fide.com/card.phtml?event=8602980
White should proceed with Rd7 creating a double check.
1.Rd7 Ka6
2.Qb7 Kb5
3.c4
threatening Qd5 or Qxa7 depending no the kings next move either to play a5 or c5. Alternatively:
1.Rd7 Ka6
2.Qb7 Ka5
3.b4 Kb5
4.Qd5 Ka6
5.b5 Ka5
6.Rxa7#

Susan… You had 3 tactics for settle this game:
TACTIC 1 :-
1.Rd7++ Ka6
2.Qb7+ Ka5
3.b4+ Kb5
4.Qd5+ Ka6
5.b5+ Ka5
6.Rxa7#
TACTIC 2 :-
1.Rd7++ Ka6
2.Qb7+ Ka5
3.b4+ Qxb4
4.axb4+ Kxb4
5.c3+ Kc4
6.Qd5#
TACTIC 3 :-
1.Rd7++ Ka6
2.Qb7+ Kb5
3.c4+ Qxc4
4.bxc4+ Kxc4
5.Qd5#
On Rh5 with discovered check, I still think white is going to lose:
1. Rh5 Kb8
Here, black has a number of options, but this holds the maximum advantage, I think. I will outline the other options below. Continuing:
2. Rh6
There is no other move for white, now. Continuing:
2. …..Qe5
3. Ka2
Safest spot for the king. Continuing:
3. …..Rd2
Keeping all the pressure on white. From here, I can’t easily tell what is best for white, but he must protect c2. The options are Qc6, Rc6, and Qc1. On Qc6, black has time for Rd1 (the checking square of e8 is controlled by black’s queen) and the white king will be forced out into the open a bit more. On Rc6, black consolidates his passed pawns with h5. So, I think Qc1 is probably the right move, keeping control of the first rank, but, like I wrote, I don’t have a good feel for this without a deeper study. Right now, I don’t know what is best for white at the start, but I don’t think it is 1.Rh5.
Rd7 double check looks like it leads to mate
One last thing before I let this go:
At move 1 in the 1.Rh5 line, black does worse with the following moves:
1. Rh5 Ka6?!
2. Rh6 Qe5
And, now, with the black king at a6, white is free to play
3. Kb1! Rd7
Here, Rd2 is no immediate threat and black will lose h7. Why is 3.Kb1 possible here but not in the other line I wrote about in my previous comment? Here is why. In the previous line
1. Rh5 Kb8
2. Rh6 Qe5
3. Kb1 g3! (Qe2 also strong here)
4. Rh7? g2! and white is toast. In the line at the start of this comment, black cannot play g3 at move 3:
1. Rh5 Ka6
2. Rh6 Qe5
3. Kb1 g3?!
4. Rh4! and I don’t see a win any longer since black’s king is extremely vulnerable. For example:
4. …..g2?!
5. Ra4 Kb5 (Kb7 6.Qg2 rough =)
6. Rb4 and I see nothing but repetition draw now.
LMAO! Can’t believe I didn’t think of a double check first. This is a motif I usually always look to find in this kind of discovered check positions. The power of the double check is that the king must be moved.
1. Rd7! Ka6 (else is mate on Qb7)
Here, though I couldn’t actually see the mate this deep, there was only one realistic move here:
2. Qb7 Ka5 (Kb5 3.c4! #s in 1or2)
Here, I had to work thru 3.Qa7 (see below), but I couldn’t find a win for white (most likely he will have to bail out into a draw since the black king escapes the mating net) but I might be overlooking something. Also, 3.Rc7 (see below) might win, too, but I still couldn’t find a mate, but all the pressure is on black in that line since black’s attack takes one move too long to get going. Best here is
3. b4 Qb4 (Ka4 4.Qa6#; Kb5 below)
4. ab4 Kb4 (Ka4 and Kb5 below)
5. c3 Kb5 (Ka5 same; Kc4,Ka4 #in1)
6. Qd5 Ka6 (Ka4 7.Ra7#)
7. Qa2 Kb5
8. Qb3 with mate on the next move regardless of what black does.
At move 4 above, black still is mated with either Ka4 or Kb5:
4. …..Ka4
5. Qa6 Kb4
6. Rc7! and the mate by c3 or Rc4 can only be delayed by one move by the sacrificial move Rc6. Or
4. …..Kb5
5. Qd5 Ka6 (Kb4 6.c3; Ka4 6.Ra7)
6. b5 Ka5
7. Ra7 Kb4
8. c3
At move 3 above, black can’t save his queen:
3. …..Kb5
4. Qd5 Ka6 (Ka4, again Ra7#s)
5. b5 with Ra7# to follow.
I will post the analysis on white’s move 3 alternatives in my next comment for thoroughness.
Rd7 dbl check and then q-b7+ and if the king runs to b5 then c4 +
followed by rd5+ and queen d5 mate
In my previous comment, I showed the double check line:
1. Rd7 Ka6
2. Qb7 Ka5
Here, I showed white has a forced mate with 3.b4, but had analyzed the alternatives Qa7 and Rc7 before proving to myself that b4 was superior. Here is the rough analysis on those alternatives:
3. Qa7? Kb5
At first, I was sure this had to be good for white- the black king is under attack of two heavy pieces, and he is up against the picket fence of the white pawns. Really, how could black survive this? However, I never could find a winning line for white, only a possible draw with 4.Rd8 equalizing the material. Lets look at some of the moves I studied here:
4. c4+ Kc5
And now what? On b4+, black takes at c4 and the king escapes through d4 to the safety of the kingside! On Rc7+, the black king plays to d4 again and escapes. The complicating factor that I could never solve was the fact that the black queen controls c7 against Qc7+, and the white rook and the a4 pawn are in the white queen’s way. Can anyone find a winning line here? Or
4. a4 Kc5 with problems nearly identical to those above. Or
4. Rc7 Rc6 (Qd4 is also ok)
And the pawn checks are just as bad as before. I still don’t see a win.
Now, at move 3, I think white has the edge with
3. Rc7?! Qd4
4. Ka2 and things are still dire for black- on Rh2, white can now play b4 opening a dangerous looking attack on black that has much similarity to the one that starts with 3.b4, but I couldn’t find the mate, only lines where black is forced to give up the queen, but that should be won for white. Here, for black, best is probably
4. …..a6
5. b4 Kb5
6. c4
Here, a4 doesn’t work to win after Ka4 followed by Kb5. Continuing:
6. …..Qc4
7. Rc4 Kc4
8. Qc7 and white will be up a queen for a rook and two pawns initially, though I doubt he can hold on to the pawns and the rook together. White should win.
1.Rd7+ Ka6
2.Qb7+ Ka5
3.b4+ Kb5
4.Qd5+ wins
On 1.Rh5+ Black plays Qf3, and White at least goes into inferior rook endgame.
I’m thinking of
1. Rd7++ Ka6 (else Qb7 mates)
2. Qb7+ Kb5
3. Qd5+ with (probable) prepetual check.
White has a mate here, and while the average player might not be able to see it from the original position, the same player could still find it by logically analyzing the position. Here’s one such player who did:
After solving this puzzle, I showed it to my piano student, Kaye. Kaye is a very intelligent 16 year old with a mild interest in chess. Kaye, who would be rated about 1600 on the ELO scale, can only see 2 or 3 moves ahead. Kaye’s forte is that she can use almost flawless logic when needed.
After looking at the position for a while, she frowned, brushed back her hair and looked at me:
Kaye: I can win the Rook back with Rook to h5, but I don’t like the ending.
Me: Me either. Is that the only way you can check?
Kaye: My Queen is attacked. Oh, I can double check at d7, then check with the Queen at b7, then take the Rook on d8. I don’t see any immediate danger after that. Maybe that will work.
1 Rd7+ Ka6 (forced)
2 Qb7+
Kaye: If he goes to b5, then c4 check kills him. He’ll have to give up the Queen or get mated.
Me: Actually, he’ll be mated soon either way after King to b5.
2 … Ka5
Kaye: Now I take the Rook at d8. Queen to d5 would be a perpetual, I think. He can move the pawn in between, though. But I can play b4 check first. That exposes my King a bit, but if I have to, I can perpetual from d5 to b7 I think….. yes, so b4 is okay.
3 b4+
Kaye: He can take with the Queen, but he’ll lose the Queen and the Rook too.
In fact, Black would be mated shortly.
3 … Kb4
Kaye: Now I can perpetual. a4 check and he takes the pawns. c4 check and he takes with the Queen. I can’t check with the Rook because his Rook takes it. So unless I want to take the Rook, I have to do the Queen move.
4 Qd5+
Kaye: King to a4 is mate with my Rook, so …
4 … Ka6
Kaye: Ah, I see it now!
5 b5+ Ka5
6 Rxa7#
Rd7 is the best move..then mate in a couple more moves.
Rd7!
