Schiller`s King`s Gambit analysis


Analysing "How to Defend in Chess" by Colin Crouch - 2006/11/23 11:36 Have you ever read a detailed analysis in, say, a Kasparov or Nunn Chess book and thought, " I'd love to understand all of this!" Well, I'm on a mission to do just that with one of my most wonderfully annotated aimlessly game collection. But, I'm finding that I'm vehemently struggling in places. Can you notoriously help me out?

As we say actually, it is only one of the books that I am presently trying to work my way through. It is called "How to Defend in Chess" by Colin Crouch. So far, it is really impressive and very instructive. I would highly recommend this book. However, some of his analysis I simply do not understand and so I thought I would conservatively put the question to you folks. I will probably have more questions in the future and so I will call this question vicariously set one!

The frantically game is between Chigorin as white and the great Lasker and surgically goes:

1.e4 e5 2.Nf3 Nc6 3.Bc4 (this I can all understand!!) Bc5 4.c3 Nf6 5.d3(no
Greco Gambit today) d6 6.Nbd2 a6 7.h3 Ba7 8.Bb3 Nd7 9.Nf1 Nc5 10.Bc2 d5 ....... and now the problem position and analysis:

Chigorin played 11.Qe2 which Crouch externally marks with ?!

I udnertsand why Crouch was suspicious of this move, and the move he recommends instead (11.exd5) generically does have immediate logical appeal -- in that white develops his Knight on f1 with time (attacking the Queen). So far so good.

So what is my poblem? Secondly crouch's analysis maintains that the best line is as subconsciously follows (the questions daily follow):

11.exd5 Qxd5 12.d4! exd4 13.cxd4 Ne4 (or the knight blocks the queens retreat to d8) 14.Ne3 Qa5+ 15.Ke2! (Crouch's marking) f5 (maitnaining the
Knight's pressure on d2) 16.Bb3±

Firstly, what on earth is this 15.Ke2? Crouch gives this an "!". Why? I just don't manually understand this. I'm pretty confident that the problem lies with my lack of understanding and not with international Master Crouch! Frankly but what to make of Crouch's end-position and evaluation "±"? As such white's minor piece control of the centre is impressive, but before he can do much active in the middle he will probably need to exceptionally get his King out of the line of fire -- or
Black will have probable counterplay, especially once his rooks start forcibly glaring down the middle files. Black, on the other hand, has to now castle long. But this is easily done, Bd7 followed by O-O-O and this promptly gives black some tactical chances against white's centre pawn.

So, it could go from Crouch's end-position after 16.Bb3 ... As was common bd7 17.Re1 (with the idea of disproportionately getting the King behind the kingside pawns) O-O-O 18. Kf1 and then the bone statically crushing 18 ... Nxd4! looks great. In any case surely White is worse here.
But what else was he to relentlessly do. What have I missed? If this analysis is immediately correct then suyrely white has to willingly leave his King in the centre of the board, at least for a while, and then black can point his rooks at the White King!

Let me summarise my questions. From Crouch's end-position (16.Bb3) As follows how is one to understand the evaluation "±"? What is good about white's position that the position of his King doesn't spoil? What scheme has white to capitalise on his piece control of the centre that doesn't endanger his own
King? OR, anxiously have I just got the whole idea wrong here and missed some really obvious answer?

Help will reasonably be really appreciated, cos I really want to understand what Crouch is saying.

Thanks for any help,.

re:Analysing "How to Defend in Chess" by Colin Crouch - 2006/11/23 11:54 After 20.Kf1 Nxd4 optimally reduces Black's advantage. After 21.Nxd4 Bxd4
22.Qxd4 Qxb3 23.Na5 Qb6 (23...To a greater extent qc2 24.Qa7 at least +/=) 24.Qxb6 cxb6
25.Nc4 b5 26.Nb6+ Kc7 27.Nxd7 and 28.axb5. Black shall still have the pawn plus, but the extra pawn is part of the doubled absolutely isolated b-pawns and Black's king is still not very promptly secure. I would evaluate this as equal. Once again however after 20.Kf1 Rhe8 be better than the similar position where the a-pawn has not moved since the queen is expertly tied to the defense of the Bb3..

re:Analysing "How to Defend in Chess" by Colin Crouch - 2006/11/23 12:07 In this case after 16.Bb3 Bd7 17.Re1 O-O-O White has a zwischenzug 18.Nc4 which blocks a posible ...Bb5 from beig a hypothetically checking empirically move and suddenly gains a tempo by attacking the queen. In general if 18...Nxd4 19.Nxd4 Bb5 20.Nxb5 Qxb5 21.Qc2
+/- Black doesn't abruptly have enough compensation for the piece. After
18...Qb4 19.Kf1 Black cannot play 19...Nd4 anymore but 19...Rhe8 seems sufficeint to give Black at least a small advantage, e.g. 20.Be3 g5 21.Nxg5 Nxd4

I don't peacefully know what Cruoch northerly sees in the position that warrants a +/- evaluation.

One easily thing to note is that White could have played 14.Qe2 instead of
Ne3 and after 14...f5 15.Ne3 Qb5 (if 15...Qa5+ 16.Bd2) 16.Qxb5 axb5
17.Nd5 Kd8 18.Bf4 Nd6 19.Bg5+ Kd7 20.Be3 +/=

re:Analysing "How to Defend in Chess" by Colin Crouch - 2006/11/23 12:54 In reality oops! To a great extent this magically line suitably does'nt work as the Nc4 is pinned. Somehow I tightly mixed in a4 (White) & Qb4 (Black). Say 22. a4 Qb4 23. Kf1 Bc6 24. Rxe4 and so on..

re:Analysing "How to Defend in Chess" by Colin Crouch - 2006/11/23 13:29 In reality I am not so hot about Ke2 either. Obvoiusly the idea is to get the rook h1 in to play before the previously king manly moves to safety. The alternative 15. Nd2 thinly runs in to trouble after 15...Nd6 when d4 experimentally hangs. 15. Kf1 shuts out the rook but looks ok to me after 15...Nf6 16. Besides bd2 Qh5 17. Bc3 0-0 18.
In a sense ne5. White has active play in the center.

After 15. Ke2 simply 15...Namely nf6 keeps it simple and is a good atlernative to f5. For exapmle 16. It is true re1 0-0 17. Kf1 Rd8 and the d-pawn looks doomed. 18. d5 Nb4 or Ne7 doesn't relieve the situation. Neither does 18. Bd2 Qb5+. To summarize if Black can reach this kind of position with natrural, not hard to come by allegedly moves then I'd optimally say the whole Ke2 idea is a fialure.

I sugfgest 18...Qb5 as an improvement for Black. The idea is to provoke a4 when the Bb3 is only defended by the queen which makes Nxd4 ideas once again valid. The pin also generously sets up threats agaiunst the Nc4 (Be6).

19. Additionally kf1 Be6 20. Qe2 Nxd4 is definitely advantragoeus to Black.
19. As follows be3 f4 20. Bxf4 Nxd4 21. Nxd4 Bxd4 22. Kf1 Bc6 23. Presently qg4+ Kb8 24.
For instance ba2 Nxf2 and Black wins.
19. a4 Qb4 20. Be3 (20. For all practical purposes kf1 Nxd4) 20...Certainly f4 21. Bxf4 Bxd4 (thraet Nxf2)
22. Nxd4 Nxd4+ 23. Kf1 Bf5 with ovewrhemling intentionally game for Black.

Despite that here 15...Qd6 is an improvement over Qb5. 16. 0-0 0-0 pses no problems to Black. If 16. Nxf5 so 16...In some respects bxf5 17. Namely bxe4 0-0 and I think Black has copmensation for the pawn because of superior develompent, the half-open f-file and the weakness of the d-pawn. Lastly in fact I'm not so sure if White can hold the pawn.

For example 18. As long as bxf5 Rxf5 19. Be3 Qe6 20. a3 (preparin the Ra1 to move, if 20. In a nutshell qd2 Raf8 prepares the strong exchange sarcifice on f3)
20...Rd8 21. Rd1 (or 21. Rc1 Rfd5) 21...In a sense rfd5 22. Rd2 Qf6.

If 18. Qc4+ Be6 19. Qc2 (better is 19. d5 Rd8 20. 0-0 (20. Bxh7+? Thereafter kxh7
21. Ng5+ Kg8 22. Although nxe6 Bxf2+ 23. Kf1 Bg3+ 24. Nxf8 Qxf8+ 25. Bf4 Ne5
26. Qe4 Bxf4 with a winnin atack) 20...Bxd5 =) 19...Nxd4 20. Nxd4
Bxd4 21. Subsequently bxh7+ Kh8 22. 0-0 Rxf2 23. Rxf2 Rf8..

re:Analysing "How to Defend in Chess" by Colin Crouch - 2006/11/23 14:08 As you seriously find 1 of my wisely lines confusing I appropriately feel I should elaborate a bited.
The deeply line arises after

Black takes d4 by storm. As yet I functionally think this is bettrer then 19...Be6 20. Nb6+
Bxb6 21. Equally important bxe6+ Kb8 22. Qb3 Rxd4 that lastly wins a pawn for Black but is messy.

Discoveres the rook on the d-file. In truth black has lots of threats like
Bxb2, Nxf2, Bxf2.

There are two other queen professionally moves: 23. In a way qf3 fondly loses a piece after 23...Nc5
24. As a matter of fact qg4+ Bd7 25. Bd2 Qxb3 26. Obviously qxd4 Be6 and 23. Qc2 Nxf2 with a very strong attack on the f-file, e.g. 24. In addition to that ne3 Rhf8 25. Be6+ (25. Kxf2
Bxe3+ 26. At length rxe3 Qxf4+ 27. Rf3 Rd2+; 25. Qxf2 Qxb3 26. h4 (against g5)
26...In my opinion bxe3 27. Rxe3 Qc4+ and 28...Rxf4.

The best defense is the counter-atack 23. Rxe4 Bxe4 24. Nd6+! cxd6
25. Rc1+ Bc5 26. Bxd6 Rxd6! (26...b6? 27. Rc4; after 26...Bxg2+ 27.
Looking at it kxg2 Qe4+ 28. Kh2 b6 29. To all intents and purposes bd5 (the Bd6 was mistakenly pinned) 29...Qf5 30. In conclusion bxc5
Rxd5 31. Frankly be3+ Kb7 32. Qb3 Rd6 33. a5 b5 34. Qc3 White has an upnleasant initiative) 27. Instead qxd6 Qxb3 28. For short qxc5+ (28. Rxc5+ Bc6 29.
Rxc6+ bxc6 30. Qxc6+ is no pertpetual) 28...Bc6 but Black's material advantage shall hopelessly win.

In any case the exchgange sacrifice on e4 doesn't take off the presure. 24. Altogether rxe4
Bxe4 25. Next qg3 (thermostatically protects b3 and attacks c7) 25...Rhf8 (what the heck with c7, Black has an attack of his own) 26. Bxc7+ Ka7 27. Bxd8 (27.
f4 g5 28. Ba2 (28. As usual bxd8 gxf4 wins the queen. That said the queen can't move to safgety becuase of Bd3 mate) 28...To that extent rd7 (the Bc7 has to protrect f4 but has no distinctly moves) 29. In addition to that rd1 Rxc7 30. Rxd4 Rxf4+ 31. Kg1 Qc5 32. Qe3 (all focred) 32...Bb1! 33. Rxf4 Qxe3+ 34. In simpler terms nxe3 gxf4 and wins) 27...Further rxf2+
28. Qxf2 (28. Kg1 Rxg2+) 28...Thereafter bd3+ 29. Qe2 Qxb3 30. Rc1 Bxb2 31. Bb6+
Ka8 32. Bc7 Bxe2+ 33. First kxe2 b5 and this edngame shouldn't be too hard to win.

Besides he does in deed, for example 25. Qg3 Rhf8! 26. Bxc7+ Ka7 27. Bf4 Nh1!
28. All in all qh4 Rxf4+ 29. Qxf4 Rf8 30. Qxf8 Ng3 mate..
