White to move. How should White proceed?
Source: ChessToday.net
1)Rg7+ Kg7
2)Qg3+ Kh8
3)Qg5 if Rg8
4)Qf6+ and then Bh6
Bh6
Rxg7+
I could go into a few varitations but whats the point.. Theres no defense…It’s pointless to discuss the simple variations like some of these scrubs like to do..
1 Rxg7 Kxg7 looks like a good start.
2 Qg4+ Kh8
3 Bg5 threatening Bf6+ followed by mate.
3 … f6 to stop Bf6.
4 Qh4 threatening both Bxf6 and now that the 7th rank is open, Qxh7 mate, and black can’t defend everything.
This is an obvious rook sacrifice. The only question is whether it works in all lines or whether one should go a little slower. Going a little slower allows some counterplay though likely even Bh6 wins. And the sacrifice is quickly calculated as sound—something that could even be found and calculated in speed chess.
1. R taken. 1. Rg7+, K*g7 2. Qg4+ Kh8 (if 2. …Kf6 then 3. Qg5#) 3. Bg5, with mate at f6 (temporarily stopped by sacrificing all pieces), so 3. …B*f6+, 4. B*f6+, R*f6, 5. Q-g7#.
2. R not taken. This transposes namely: 1 Rg7+, Kh8 2. Qh5 forces K-g7 and then simply the same as line 1 above, 1 move later.
Psyche (though anonymous)
i think, we can play
1. Rxg7+ Kxg7
2. Qg4+ Kh8
3. Bg5 Bxb2+
4. Kb1 f6 (f. e.)
5. Bxf6+ Rxf6
6. Qg7#
1.Bhg6 g6 2.fxg6 hxg6 3. Qf6 ***Black resign because white only had 1 step for checkmate (KO) at Qg7# – MR KO (Malaysian)
1. Rxg7+ !

A fascinating Position and a very instructive one as well. I believe the right move to be
1. Rxg7+ !
To take or not to take, that is the question.
If
1..Kxg7 than
2. Bh6+ !
With the purpose of luring the King further from home. Thus winning a crucial tempo (time). On h6 the King is one step further from the (relatively) safe square of h8. In other words it will take the King one move more to drive home to h8.
2..Kxh6
3. Qe3+
Her majesty is coming to join the joy ride. Her goal is to reach g5 square with a check!
3…Kg7
3..Kh5 prolongs the ride. 4. Qh3+ Kg5 5. Qg3+ Kf6 6. Qh4+ Kg7 7. Qg5+ and we are in the main line.
4. Qg5+ Kh8
5. Qf6+ Kg8
Now comes the cute punch:
6. Rd2!!
A backward Rook lift!
6…Bxf5
only move. But..
7.exf5
Simple.
7….Qd5
8. Nxd5 and next move its mate.
9. Rg2#
Best wishes amd Happy Holidays.
Oh! I almost forgot: Bravo to the New Delhi tactician!!
A. Weiler
Appendix A: If Black doesn’t take on g7
1. Rxg7 Kh8
2. Rxh7+!
Pretty!
2..Kxh7
What else?
3. Qh5+ Kg8
Let’s look at 3..Kg7. 4.Bh6+ Kh7 5. Bg5+ Kg8 6. Bf6 and 7. Qh8#. And if 5…Kg7 6.Qg6! Kh8 7. Bf6#
4. Qg5+
4…Kh7
If 4..Kh8 5. Qf6+ leads to the main line.
5. Qg6+
5..Kh8
6. Qf6+ Kg8
7. Bh6 Black anywhere.
8. Qg7#
Appendix B.
1. Rxg7 Kxg7
2. Bh6+ Kh8
This leads to the main theme too!!
3. Qg4
3..Rg8
Only move.
4. Qh4.
Threatening mate in two.
4.. Bf8
Only move.
5. Bxf8.
Threatening mate in two.
5..Rxf8
Only move.
6. Qf6+
We are back to the main theme.
6… Kg8.
7. Rd2!! and wins.
I’m sorry Susan, but I have to respond to wolverine’s
post of December 26, 2010 1:25:00 AM CST. It is obvious
that wolverine does not understand the purpose of your
wonderful blog. It is for chess information dissemination
and chess instruction. wolverine said “It’s pointless to
discuss the simple variations like some of these scrubs
like to do.. “
Well, wolverine, not everyone who reads this blog is as
good as you seem to think you are, so at least this “scrub”
will continue to give variations so others might learn.
For instance, why is Rxg7 a better initial move than Bh6?
Is white’s attack on the black king sufficiently fast that
blacks threats of Qxc3 and Bxb2 won’t result in a black
victory? If afer Rxg7 and Kxg7 what is white’s best continuation?
If the best 2nd move is a Queen check, then on what square
g2, g3, or g4 and why is your choice best. Perhaps someone
posts that f6+ is best. How are we to decide if no variations
are given.
Personally, I would have ignored your post if it wasn’t for your
“scrubs” comment. Just you posting Rxg7+ without explanation
means nothing to me. Even if your move is the correct one, why
even bother posting if you don’t defend your post.
There is the added bonus that if your analysis is faulty, some
other poster might correct your analysis, and even you might
learn something even if it is from a “scrub”.
it shouldn’t be more complicated than this:
1)Rg7+ Kg7
2)Qg3+ Kh8
3)Bg5
the f6 check is terminal and playing
3)f6
to block it puts another attacker on g7
4)Bh6 now wins
