White to move. How should white proceed?
Source: ChessToday.net
Well known theme is at work but requires some refinement.Waiting for some comments to appear first.
How come this game has not appeared in chessgames.com even though some other game of Bronstein in hastings 1953 has appeared?
1Ra7 qd8 2Qd7 q any 4Qxp ch wins
Because of the threat Rf8+, followed by mate, Black may not remove his queen from the 8th rank, and therefore White can afford to play
1. Qc6 Rxg3+ – delaying queen moves
2. Kh2 Rh3+
3. Kg2 Qb8
An only move; the queen must not protect pawn d5 from d8, since White would take on d5 with a double attack on queen and king.
4. Qb5!Again there is only one square left for the black queen not protecting d5:
4. … Qc8
4. … Qa8/d8 5.Qxd5+ ~ QxQ
5. Ne7+ Kh7/h8
6. Nxc8 and White should win easily
1.Qa7Since In BQ’s absence 1.Rf8+ Kh7 2.Rh8# a deflection sacrifice is made.It is necessary to block QR file, as otherwise black’s attack may become menacing. e.g. 1.Qb7 Rxg3+ 2.Kh2 Rh3+ 3.Kg2 Qa2+ and now if 4.Rf2 ,Rh2+ could be disastrous.
1…… Qe8 /Qd8
2.Qd7 This eyes R at g3 also.
2…. Rxg3+
3.Kh2 Rh2+
4.Kg2 Qb8 The deflection tactic has failed but black has committed his R a position only guarded by N.Now N has to be deflected.
5.Rf8+ Qxf8
6.Qxd5+ Nf7 forced. 6…. Qf7 allows 7.Qa8+ Qf8 8.Qxf8+ Kh7 9.Qh8#. it may be noted that black had no chance to take “h” pawn with his R.
7.Nxf8 Rxh5
8.Ne6 White has Q for R and wins technically.
Prof. Bhat: I agree that 1. Qc6 might be a bit dangerous because of the counterattack you described. However, why not
1. Qa5 instead of Qa7? After
1. … Rxg3+
2. Kh2 Rh3+
3. Kg2 Qb8/e8 Where else could Her Majesty go?
4. Qb5 Qc8
5. Ne7+
White will be a queen up for three pawns, which in my opinion is slightly better than having a queen for a rook 🙂
fajac,
Frankly i had not thought of 1.Qa5 but when I considered 1.Qa7 I tried to prevent 1…. Qb8 also.At that time I had thought of 1.Qa7 Ra4 but laughed out at my stupid idea when 2.Qxa4 dawned on me but i recalled that idea after 1.Qa5 Qb8 2.Qb5 Rb4 which is not a laughable matter since from b4 you can control f8.
1.Qa5 Qb8 2.Qb5 Rb4 3.Qxd5+ Kh7 now
4.Rf8 looks very strong but black may have some counter play .Of course following moves may not be forced but underline the danger for white also.
4….. Rb1+ 5.Kg2 Rb2+ 6.Kf1 Rb1+ 7.Ke2 Qb2+ 8.Qd2 Qb5+ 9.Qd3 Rb2+ 10.Ke1 Qa5+ 11.Kd1 Qa1+ 12.Qb1 Qxb1#Of course WK can go to 6.Kg2 possibly repeating the moves.
# fajac
….. Qc8 I had rejected from the beginning.
Rather white has better things than 4.Rf8
1.Qa5 Qb8 2.Qb5 Rb4 3.Qxd5+ Kh7 4.Nf8+ Kh8 5.Nd7 Nh3+
(5…Qc8 6.Rf8+ Qxf8 7.Nxf8 white wins easily )
6.Kh2 Nf4 7.exf4
(7.Rxf4 exf4 8.Nxb8 fxg3+ 9.Kxg3 Rxb8 also1-0)
7…Qb7 8.Qxb7 Rxb7 9.Nxe5 with easy win.
In chessgames.com i had searched in vain for his game in 1953 but now I find it in 1954 here is the game.
“Bronstein vs Teschner Hastings 1954” Bronstein was more practical. After 1.Qa7 Rxg3+ 2.Kh2 Rh3+ 3.Kg2 Qe8 he played 4.Rb1 Neither K nor q could run away e.g. 4… Kh7 5.Rb8 could follow and if Q moves it would be mate. If Q runs away then also it is mate but black played 4… Nf7 leaving his R stranded.
My html for the game link seems to be incorrect
From November 2011:

Oh! Yancey,
I had forgotten everything I had analyzed as shown in your link and my interaction with fajac is almost the same.
fajac,
1.Qa7 does not deserve “?” mark. If you want 1.Qa7 Qe8 2.Qd7 Qb8 3.Qb5 I am following you one move behind.
fijac,
we will come to a compromise. we shall first play
1.Qa7
(1) if black replies 1….. Qe8 2.Qd7 will be nice.The R at g4 we will get free if black plays 2….Qb8.
(2)If black plays 1…. Rxg3+ 2.Kh2 Rh3+ 3.Kg2 Ke8 still we will play 4.Qd7 and now if 4…. Qb8 5.Qb5 will settle the matter since black R is not in a position to move to file “b”.
There is some flaw in the analysis of both of us.will post it in the evening.
fijac,
When white K is at g2 , Qxd5+ by white is well replied by ….. Qxd5 since it is a check to white K.
So 1.Qa5 Rxg3+ 2.Kh2 Rh3+ 3.Kg2 Qb8 4.Qb5 black can play 3…. Qa8 since 4.Qxd5+ is met by 4…. Qxd5+ not simply winning Q but leading to mate. This I realized after I wrote the last note but my first version still works.
fajac,
I feel am extremely sorry for misspelling your name.
Dear Prof. Bhat,
First of all, don’t worry about the name – it’s only a nick =;-)
I guess your analysis is right, thanks for the hint.
fajac,
Thank you very much for the tolerance.People do not like their name twisted whether true name,nick name. I went back through your comments and found that your 1.Qa7? the question mark does not refer to the move but is associated with the word “why”.A sort of misunderstanding on my part and you know I had also written 1.Qa7 does not deserve question mark.
