Hi Susan Polgar,
Ref:”Giri chess tactic”[White’s move]
Sub: White wins the game.
Well,this sounds pretty ease for White to win,there exist some interesting combination,let me give two examples.
Example one
===========
1.Qh6 Qg7
2.Be6+ Rf7
3.Rd8+ Be8
4.R*Be8 Qf8
5.R*Qf8++ Mate
Example two
===========
1.Qh6 Qg7
2.Be6+ Kf8
3.Rd8+ Ke7
4.Q*Qg7+ K*Rd8
5.Q*Ra7 b5
6.Qd7++ Mate
By
Venky[Chennai – India]
I like starting it by Qa6 with the threat of Qxg6 and Be6+, because Rd8+ threats mate.
So I think Qxg6 becomes hard to defend, giving white a pawn up and opening a long term attack to the black king.
e5
The opening shot isn’t hard to find. e5 just opens up the lines and diagonals too beautifully for it not to make it to a very short shortlist 🙂
The complications arise when black defends. One example is actually seen in the actual game continuation:
e5! Bd7?! Qc4+ (An unnecessary move since white has to backtrack on the best response … Kh7 Qh4+ Kg8 Rd6! It might be that Giri had little time left and was playing the clock.) Kh8 (Black obliges by playing suboptimally and its game over) Bxd7 Rxd7 Qc8+ 1-0
1.e5! threatening Qc4 if 1…Kg7 2.exf6+ Qxf6 3.Qxf6+ Kxf6 4.Rd6+
and 2.exf6 to follow
1. e5, for if Black takes the pawn, 2. Qc4+ picks up the B. 1…f5 also suffers the same fate, so Black must move the B, allowing 2. ef with many threats.
1. e5! is good considering the hanging black bishop. but the further play I am unable to make out. White definitely has some advantage.
1. B-e6+ would work except for
1. … K-g7.
So:
1. P-e5 threatening 2. Q-c4+ and
then 3. Qxc6
Late to the party, but since I had already seen this game yesterday, I knew what move Giri played. It appeared to me that his opponent blundered a couple of moves after this by leaving his king on the back rank:
1. e5 Bd7
2. Qc5 Kh8?? (Kh7 better I think)
3. Bd7 Rd7
4. Qc8 and black resigned since his rook was toast. However, after e5, black’s position was bad even with proper play, but white’s weak back rank would have allowed black to fight on. One line is:
1. e5 Qc5 (what else is better?)
2. Kh1 f4 (fe5?? 3.Qh6!)(Qe5 3.Qc5)
3. Rd8 Be8 (only move)
And now white has to worry about his king and cannot take at e8:
4. Re8? Kf7 with twin threats.
I think white probably does a bit better with queen check at d8:
3. Qd8 Kh7
But even in this line, I am having a hard time seeing a really strong continuation. Pushing e6 seems to fail to Re7. At move three, the line I like best is
3. Bf5 gf5??
4. Rd8 Qf8 (Kg7 5.Qf6 Kh7 6.Rh8#)
5. Rf8 and black will lose his bishop as well. At move three in this line, black should play:
3. …..Qe5
4. Bg6 Bg2 (only move I see)
5. Kg1 Qe3 (forced)
6. Qf2 Qf2
7. Kf2 Bh3 (Bc6?! 8.Rd6!)
And, I think white has an advantage in this endgame with the passed h-pawn, but he has work to do to realize the win.
Just my two cents worth. Will be curious to see if anyone can come up with a more definitive advantage for white in this line starting with 1.e5.
The problem with Venky’s solution is that in Example 2, the Black bishop can interpose:
1. Qh6 Qg7
2. Be6+ Kf8
3. Rd8+ Be8
and White has no winning continuation.
After 1. e5, Black doesn’t have to take the pawn on e5, with either the queen or his pawn. Black can put White king in check with 1… Qc5+. I think that is the critical variation. In this line, after 2. Kh1, if Black takes with Pxe5, then (and only then) does Qh6 look very strong.
After 3. Qh6, Black can defend with
Be8.
Now (and only now) is Be6+ really effective.
So the 1. e5 move acts as a way to
deflect the Black queen, making a later White Qh6 effective.
It took me a long time (too long) to find 1. e5
Lucymarie
Ok, here is one line for white’s third move I had missed completely that might offer white more advantage:
1. e5 Qc5
2. Kh1 f5
3. Qg5 Be8 (forced, I think)
4. Rd8 and now black has a few options:
4. …..Qf8
5. Bf5 Qf5 (only move)
6. Qf5 gf5
7. Re8 Kf7
8. Rb8 Re7 (b5? 8.Rb6!!)
9. Rb6 Re5
10.g3 Ra5
11.Rb2 and I like this endgame better for white than the one that arises in my previous comment, but, still, white has significant work ahead.
All in all, I am starting to wonder whether 1. e5 really was the strongest move for white- he gets an edge, but I am finding only a stronger rook pawn endgame, nothing truly decisive yet.
In my comment at 10:14 a.m., I meant 2. ….f5 where I wrote f4.
Hi, Yancey. After
1. e5 Qc5+
2. Kh1 f5
3. Rd8+ and if Black does not
interpose the Queen on f8, then
White mates after either
3…. Kg7
4. Qh8+ Kf7
5. Qf6#
or
3… Kf7
4. Qh7+ Ke6
5. Qxg6+ and then if
5… Ke7
6. Qf6# or else
5… Kxe5
6. Qxf5#
Lucymarie
Hello again, Yancey. I blew it. I totally missed your comment about the bishop interpose after
1. e5 Qc5+
2. Kh1 f5
3. Rd8+ Be8
where 4. Rxe8+ runs into Kf7 and White is starring at that back rank mate. Hmmm…..
Lucymarie
OK. After
1. e5! Qc5+!
2. Kh1 f5!
3. Rd8+ Be8
4. Qh6
how is Black going to defend?
It seems like the possibilities are:
4… Kf7
4… Rg7
4… Qf8
After
4… Kf7?
5. Bxf5! gxf5
6. Qf6+ Kg8
7. Rxe8+ Kh7
8. Rh8#
After
4… Rg7?
5. Rxe8+ Kf7
6. Ra8 appears to be winning
After
4… Qf8! it looks like there is a lot of play still
left in this position. White can try
5. Qe3 but I think it’s a draw.
Maybe a chess program can find a win from this, but I can’t.
Lucymarie
I see a lot of agonizing after e5 Qc5+ Kh1 f5 :)Please do drop the exclamation marks after the black moves since white have two near killers in Bxf5 and Qd8+ followed by Bxf5.
All hue and cry makes my earlier anonymous point that the complications begin as black defends. But not to worry e5 first is a killer move.
Well, Anonymous, show us how each of those line will proceed. I have looked at both and don’t see a quick “killer” knockout, just advantage to white.
Hi Susan Polgar,
Well,Very nice,brainy minds had given one of the best moves.
Now out of my two examples : “Lucymarie” had taken the second example and said that “White has no wining continuation”,if Black replies with “Be8” in 3rd move.
Well,I appreciate “Lucymarie” for pointing out that if Black’s reply in 3rd move is “Be8”,the mate will not happen the way I had said,I have overlooked that position – thanks for pointing out.
But I differ with “Lucymarie” about her view that thereafter “White has no wining continuation”.
My opinion is,still White can win the game with minimal concentration.
Let me given here an example for it.
1.Qh6 Qg7
2.Be6+ Kf8
3.Rd8+ Be8
4.Qh4 Rc7
5.h3 Rc1+
6.Kh2 f5
7.Qf4 Ra1
8.Bd7 Qe7
9.R*Be8+ Q*Re8
10.B*Qe8 K*Be8
11.Qe5+ Kf7
12.Q*Ra1 f*e4
[ Now its every much clear that White’s win assured ..but just for the sake of interest,let me continue and complete the game bit lengthy.]
13.Qe5 b5
14.Q*e4 a5
15.Qd5+ Kf6
16.Q*b5 g5
17.Q*a5 Kg6
18.Qb6+ Kh5
19.a4 g4
20.a5 g*h3
21.K*h3 Kg5
22.a6 Kf4
23.a7 Kg5
24.a8(Q) Kf4
25.Qa5 Ke3
26.Qb4 Kd3
27.Qa3+ Kd2
28.Qb2+ Kd1
29.Qa1++ Mate.
White wins the game.
