White to move. How should White proceed?
Source: ChessToday.net
I think the following continuation is good for white:
1.Rxd6
a) if
1…Bxg4
2.Re8+ Qg8 (forced)
3.Rxh6+ Kg7 (forced)
4.Rg6+ Kf7
5.R(any)xg8 Rxd3
6.fxg4
leaving white a rook up.
b)
1…Rxd3
is met by Rxd7 or Qxd7
again a rook up.
c) only square left for black bishop is a4
1…Ba4
2.Rd8+
loses the queen
d)
1…Bc8
2.Rd8+ Qg8 (forced)
3.Rxg8+ Kxg8
4.Bf5
white is able to cover his queen…
Rxd6?
It seems that works 1. Rxd6 …., with some variants but all them are lineal and are easy to discover.
Rxd6
RxN looks good to me. If …BxQ, then Rd8+, Qb8; Rxa6+, Kb2; Rb6+ wins the queen back with interest.
Make that RxN, BxQ; Re8+! If instead of BxQ black plays RxB, then RxB wins.
Black’s in a whole lot of trouble.
I suppose theoretically what makes him so vulnerable is a combination of thing — the ‘nakedness’ of his king, white’s control of the e-file, white’s excellent bishop, and white’s space advantage. The fact that white is up the exchange helps too.
Black is barely hanging on. So, white forces the issue with:
1.Rxd6!
2..Bxg4 3.Re8+ Qg8 4.Rxh6+ Kg7 5.Rg6+ Kf7 6.Rexg8, black is down a rook and has to watch out for back-rank mate threats.
2..Rxd3 3.Rxd7 Qf8 4.Qf5!
1. Rxh6+! Qxh6
2. Qxd7 with the threat of Qd8+ as well as Rd6.
Hope white is winning.
1.Rxh6 Kg8!
After
1.Rxd6! White protects d4 and attacks the 8th rank with desastrous threats.
Kind regards, Jean-Claude
White has two winning moves in my opinion- 1.Rh6 and 1.Rd6. Considering Harridaran’s comment has already posted, I will just assume Rd6 is the stronger solution and analyze that one first (I would choose it anyway since it is clear and utterly forced):
1. Rd6 Bg4 (what else?)
2. Re8 Qg8
3. Rh6 Kg7
4. Rg6 Kf7
5. Rgg8 Bh5 (Rc1 no better)
6. Be4 and white should win this. I don’t immediately see a mating net, but I am not looking too hard for one here since the position is so clearly won for white.
The other first move for white also wins:
1. Rh6 Qh6 (Kg8 see below)
2. Qd7 Rd3 ()
3. Re7! Rd1 (nothing better)
4. Kf2 Qh5 (nothing better)
5. Qd8 Ne8
6. Re8 Qe8 (Kg7 7.Rg8 mates in 5)
7. Qe8 Kg7
8. d5
and the pawn can’t be taken
8. …..Rd5
9. Qe7 Kh8 (Kg8/g6/h6 10.Qe6)
10.Qf8 Kh7
11.Qf7 bags the rook. At move 1 in this line, black does no better with
1. …..Kg8
2. Bh7 Kf8 (Kh8 3.Qd7 Qd7 4.Bf5)
3. Rd6 Bg4 (what else?)
4. Rd8 Kf7
5. Bg6 Qg6 (Kf6 6.Rd6 Be6 7.Ree6#)
6. hg6 Kg6
7. fg4 and white should win.
Clearly, 1.Rd6 is clearer to see and provides a bigger edge.
White is up the exchange for a pawn, but his Rook is pinned against his Queen, his Bishop is under attack, and Black threatens Qxd4+. On the bright side, Black’s king is somewhat exposed and White has doubled rooks on the e-file.
I fooled around with the idea of Rxh6+ for a while but couldn’t come up with anything.
Rxd6 is tempting though, covering d4, threatening Rxd7, and if the Bishop moves, Rd8+ picks up the Queen. Let’s see what Black can do.
1. Rxd6
1. … Rxd3 2. Rxd7 and Black is just down a Rook for a pawn and White has a strong attack.
1. … Bxg4 is more interesting. White can pick up Black’s Queen for a Rook easily, but will end up down at least a pawn unless he can come up with something clever.
1. Rxd6 Bxg4
2. Re8+ Qg8 (forced)
3. Rxh6+ Kg7 (forced)
4. Rg6+ and White picks up the Queen without having to give up a Rook for it. White ends up a Rook for a pawn up.
Hi Susan Polgar,
How are you all ? I have now logged into internet after many days.Hope you all had interesting days of chess puzzle solving.
Okay coming to this chess puzzle.
Ref: “U.S. Junior Chess Tactic”[White has to move]
Sub: White wins the game.
Well,I will go with the given below moves.
1.R*nd6 R*Bd3
2.R*Bd7 R*d4
…….
Rest of the moves are child’s play for white to win the game.

After 1. Rxh6+, of course, Black need not capture on h6. After 1. … Kg8, Black’s bishop is attacking the White queen, limiting White’s options.
As an alternative to 1. Rxh6+, perhaps
1. Rxd6
and White is up a Rook with continuing threats, since
1. … Bxg4
2. Re8+ Qg8
3. Rxh6+ Kg7
4. Rg6+ Kf7
5. Rgxg8
Since White is also threatening not only 2. Rxd7 but also a check on the eighth rank if the Black bishop moves, the only alternative to 1. … Bxg4 seems to be 1. … Rc7, but then 2. Bf5 and White maintains an extra rook and an attack.
