"With this in mind, Lasker courageously refrained from..."

Lasker had quite another conception of the problem posed by the position...Lasker therefore decided that his immediate task was to await events so as to see how his opponent's plans would develop. But this idea of waiting is tied up with the notion [ala Sun Tzu] of seizing the opportunity during a regrouping on the opponent's part of organizing an eventual and successful counter-attack, thereby extracating himself from the difficult straits [in] which he lies."

"As can be seen from these moves, Lasker has proved right with his...tactics."

"...Lasker cannot remain passive any longer and he therefore decides to...keep his opponent preoccupied..."

"It should be observed that [Lasker's opponent] still does not know what procedure to adopt so as to increase his advantage."

"With his next move he [Lasker] comes to the decision to harass his opponent...and in this manner to divert his attention...So he must be prepared to go through the hurly-burly of a hand-to-hand fight [i.e., STRUGGLE] without flinching."

Lasker "has perplexed [his opponent] and obviously caused him to lose the thread of the game."

"...one can again and again set the opponent difficult problems and this Lasker really has done with great skill. In actual practice it often occurs that the player with the advantage plunges for inadequate methods if the solution to the problem is made sufficiently difficult for him the whole time."

"Just one heedless move by the opponent and at once Lasker strikes!"

"Suddenly [Lasker's opponent] sees difficulties looming up (it is only too well-known that such difficulties have a most depressing effect when they suddenly appear in a superior position. It is then that there come the horrid mistakes and oversights)."

"This is what the wily old fox [Lasker] was waiting for! [Lasker's opponent] misses the fruits of his good play up to this point...So, suddenly, weaknesses appear in the facade of the good position and in such cases one seldom finds the best defense."

"A wonderful defensive achievement by Lasker. One could quote a host of examples like this in which Lasker rescued himself from desperate situations through a resourceful defense."

"Lasker was purely and simply a great fighter who could also put up a tough fight in inferior positions, in this way being able to save many a difficult position."

Nice Quotes!!!

To be more exact, Keres first wrote these for the Shakhmaty v SSSR, 3rd and 4th issues, 1964, "Defending Difficult Positions". There are interesting quotations for Lasker moves at 27th (a3), 29th-31st (Ka2,Ka1,Ka2).

The Bronstein's isnt referring to this game in particular but just some paraphrase that the speaking author appointed to his own game/situation. And as follows:

Bronstein when asked about defending the difficult positions: "I just tried not to make my position worse, more importantly, did not try to make it better""

Colin Crouch in his book How to Defend in Chess:"There is always the danger for the defender that he will try to "refute" this passive play, and overpress, thereby creating weaknesses and accelerating defeat. Laskaer doesnt try to improve his position, his pieces are ideally placed for defense anyway."

<Raymond Keene>
<Better 37...Kd8>
This words have the ambiguous meanings. Yes its better than 37...Nf6 but the best move BY FAR is 37...Qh8!.

After 37....Qh8 38.Qg2/Rg2

38.Qg2 Nf6! 39.h4 39 Ng4....now the rooks trapped..most likely 0-1

Its better 38.Rg2 Rg8! 39.Rxg8+ Qxg8 40.h4 (40.Nd2 Qh7 41.Nf3 f6 42.Bc1 Qh3...now black has a superb position) Qg4 41.Bg5 Nxg5 hxg5 42.Bf4....Now black would get the second pawn...0-1

So, with the 37...Qh8, even with the high skilled defense, Lasker wouldnt have a chance to save the game.

Keene suggested 37...Kd8, its worse than 38...Qh8.

37...Kd8 38.Ng5 Qxh2 (38...Nxg5 39.Bxg5+...even nearer to the equality) 39.Nxf7+ Kc8 (39...Ke8 40.Rg2 Qh7 41.Ng5...black just slightly better) 40.Qd3...now black just SLIGHTLY better.

In the actual game after 38.Bg5, the position is very complex, its likely impossible to mapping all the variations. Noted there are 38…Nh5/Ne4/Nd7. For the wisdom of the imaginative minds…all the three deserves to try and of course would plunge to the oceans of variations. There is a semi-trap to get a better position. Aberration would bring to the disaster. 38...Ne4
39.Be7? (Be3 far better) Re8!

40.Rxf7 (now blacks better although its hard to harness the advantages) Qg4!

41.Bh4 (interestingly, I cant decide which better Bh4/Ba4) Qg8

42.Re7 Rf8
43.Ne5 Bd8

44.Nxc6 Qh8 (44…bxc6 45.c5 threatening Qxa6+ only bring the draw)

45.Nxd8 Qxh4

46.Rxb6 Rxd8…now black better with 3 pieces compared to white 2 pieces.

If 43…Bd6?

44.Nxc6 Bc7= (now this is the point black now hasn’t 44…Qh8 because 45.c5 Bxe7 46.Nxe7+ Kd7 47.Ng6 would turn the table ) Of course not also 44…bxc6 45.c5 threatening Qxa6+ or cxd6.

I´ll second that.And add that studying this game for say 4-5 hours will really pay off in the long run.
