Two Knights Defence without Tears:
Part 2
Last month I began my survey of some lines in the Two Knights Defence (1
e4 e5 2 Nf3 Nc6 3 Bc4 Nf6). I emphasised in Part 1 that this is an opening
where a player or student can easily become overwhelmed by the mass of
unclear complications that can arise. Publications that pile example on
example, omitting no practical example tactical detail do have their place -
for advanced and correspondence players. However, they leave the majority
of readers not being able to see the wood for the trees.

My objective in this series of articles is to give an overview of the Two
Knights. If you want detailed examples to analyse, you can then download the
games from my website and study them. This file now contains material of
the variations discussed this month in addition to the games already in the file
last time. Here is the URL: http://www.chessmail.com/freegames.html.
1 e4 e5 2 Nf3 Nc6 3 Bc4 Nf6 4 Ng5
Before we get on with the main topic of the article, there are two digressions
relating to Kibitzer.
Firstly, I asked readers for the source of Dr Tarrasch’s famous “duffer’s
move” put-down on 4 Ng5 and several of you gave me the answer. The
colorful phrase used by Tarrasch, not easy to translate into English is “ein
richtiger Stümperzug”. A “Stümper” is not an Australian cricket
wicket-keeper but (according to my dictionary) is a botcher or bungler or
clumsy fellow.
The most detailed comment came from Stefan Bücker, editor of the German
theoretical/historical magazine Kaissiber . He informed me that Tarrasch's
remark was made in his Die moderne Schachpartie , e.g. 2nd. ed. (Leipzig
1916), p.294, commenting on 4 d3 in Salwe-Schlechter (Carlsbad 1907):
“Wohl nicht so energisch wie d2-d4 oder 0-0, aber sicherlich viel besser als
der so häufig an dieser Stelle gemachte Zug Sg5, den ich für einen richtigen
Stümperzug halte.”
Which I loosely translate as follows “Probably not as energetic as 4 d4 or 4
0-0, but surely much better than the move so frequently made in this position
4 Ng5, which I hold to be a real bungler’s move”.
Modern theory doesn’t often agree with Tarrasch. For example in his 1965
book on Open games in his 4-volume openings series, GM Ludek Pachman
wrote that:

The Kibitzer
“Opinions about the soundness of the move 4 Ng5 have often changed over
the course of time. While it found little approval with Dr Tarrasch... in
modern practice, it is considered a very sound continuation, even the best
reply to 3...Nf6”.
It was preferred by the 7th Correspondence World Champion Yakov Estrin,
who enjoyed playing the resulting positions with either colour both in postal
and regular play, while in recent GM practice, for example, GM Alexander
Morozevich has been employing this move against the Two Knights.
4...d5 5 exd5 ( See Diagram )
My second digression, before I go on
to discuss 5...Na5 and 5...Nd4,
concerns the Lolli Variation 5...Nxd5 6
d4 which was briefly mentioned last
month.
Dan Heisman tells me he has a lot of
new analysis to show that Black’s best
line is not 6...Bb4+ or 6...exd4 but
rather to “fall into the trap” by
6...Nxd4. Then after 7 c3 he should
play not 7...Ne6? 8 Qxd5 but either
7...f6 or 7...b5. His new electronic book
from Pickard & Son, dealing with the Fegatello and Lolli variations, will
include his proof of this and I look forward to it. Mr Heisman also points
out that his Traxler electronic book is not just an encyclopaedia of old
games and analysis but contains more new (computer-assisted) analysis
than most opening books
Now for the heart of this article. This second part covers the lines where
Black, after 4 Nf5 d5 5 exd5, employs either the standard 5...Na5 move.
I had originally intended to include the 5...Nd4 Fritz Variation (possibly
reaching the Fritz via 5...b5) in this article also but by the time I had
completed 5...Na5 this Kibitzer was already longer than the last. Since
5...Nd4 in itself is quite a big subject, it will be reserved for a third and
final part of the series next month.
Both 5...Na5 and 5...Nd4 answer the threat from White’s d-pawn by
moving the Knight while 5...b5 counter-attacks the white Bishop. I am
going to look at 5...Na5 first because it is the move that obtains the most
coverage in books, and is played most often of Black’s options against 4
Ng5. Also, I suspect that I shall find it hard to maintain my “wood not the
trees” approach so easily when dealing with the Fritz, which is almost pure
tactics. However, I will try.
5...Na5 ( See Diagram )

The Kibitzer
With 5...Na5 Black avoids losing a
tempo and plays to get developed
before launching a full-blooded tactical
bout. This probably explains why it is
more popular than the alternatives.
6 Bb5+
This check is virtually forced. It is
possible for White to concede the
Bishop pair by 6 d3 but this move is
hardly in keeping with the previous
aggression. Black should answer 6 d3
by 6...h6 7 Nf3 e4 when 8 Nd4 can be
met by 8...c6 and the piece sacrifice 8 dxe4 Nxc4 is unsound. So White
plays 8 Qe2 Nxc4 9 dxc4 and now Morphy’s move 9...Bc5 (hindering
Nd4) is still considered best.
6...c6
There is a strange reluctance to try Polerio’s move 6...Bd7!? which has not
really been tested or refuted yet. The upside for Black is that he may very
easily regain his pawn without compromising his queenside pawn
structure. The downside is that the pawn on d5 cramps him, and leaves the
a5-Knight vulnerable with no move at present. For both sides, this
variation is relatively unknown territory so if Black prepares 6...Bd7 he
could score well with it, and White needs to be aware of the possibility.
( See Diagram )
If White exchanges Bishops then after
7 Bxd7+ Qxd7 Black immediately
regains his pawn with a good game
(Ciric-Nesis, corr 1982) so 7 Qe2 is
necessary. Then Black has a choice
between 7...Be7 and 7...Bd6. The
former move keeps open the possibility
of capturing early on d5, whereas the
latter secures the e5-pawn and intends
to “play around” the advance d-pawn.
It also sets a trap.
Morozevich-I.Sokolov, Sarajevo 1999,
went 7 Qe2 Bd6 8 Nc3 0-0 9 Bxd7 (Avoiding the trap 9 0-0? Nxd5! 10
Bxd7 Nf4 11 Qg4 h5 12 Qh4 Be7.) 9...Qxd7 10 a3!? (If 10 0-0 then 10...b6
or 10...c6.) 10...b6 (necessary to save the Knight) 11 d3 (If 11 0-0 instead,
then 11...Nb7 12 b4 a5! according to Jozsef Palkovi, not 11...Rae8 12
Qa6!) 11...c6?! 12 b4! Nb7 13 dxc6 Qxc6 14 Nce4 Nd7? (14...Be7 leaves
White somewhat better.) 15 Qf3 Be7?! 16 Nxh7! and White won. As
Palkovi shows in his 2000 book Zweispringerspiel bis Traxler
Gegengambit , all this happened before in a 1996 Spanish game
Arnold-Iruzubieta, which doesn’t say much for GM Ivan Sokolov’s
preparation! Maybe he was misled by the fact that the Spanish game was a

The Kibitzer
short draw but Morozevich improved on it. Instead of 11...c6, Palkovi says
11...Rae8 is the right move since Qa6 is not possible in this line.
English GM Glenn Flear prefers to play 7...Be7. Then after 8 Nc3 0-0
White often chooses the safe 9 Bxd7. However, when he doesn’t hold the
gambit pawn he doesn’t really obtain winning chances e.g. 9...Qxd7 10 0-0
(if 10 d3 Nxd5) 10...Rfe8. On the other hand, 9 0-0 leads to obscure
positions. Herbrechtsmeier-Nunn, Bundesliga 1985, went 9...Bg4!? 10
Qxe5 Bd6 but this may not be good enough. Instead 9...c6 10 dxc6 Nxc6
seems to offer compensation. It may seem strange to avoid ...c6 earlier and
then play it after all, but White’s move Qe2 is not especially constructive.
Returning to 6...c6 , play invariably goes 7 dxc6 bxc6 reaching the next
diagram. ( See Diagram )
White must now either retreat the
Bishop or pin the c-pawn along the
diagonal. We look at the latter
possibility first.
8 Qf3
White tries to induce either a passive
defence of the c-pawn or else the
incorrect exchange sacrifice 8...cxb5?!
9 Qxa8. Instead Black can reply with a
move that was analysed by an English
prisoner-of-war in a Japanese camp
during World War II:
8... Rb8!?
It would now be foolhardy in practice (whatever your computer might say)
to grab the second pawn at c6. After 9 Bxc6+ Nxc6 10 Qxc6+ Nd7 White
has no piece in play except his Queen and the g5-Knight which is under
attack. Black will bring out his King’s Bishop, castle and then enjoy a big
lead in development and open lines.
Therefore the prudent move is to retreat the Bishop:
9 Bd3
Not to e2, because you could have done that last move if you wanted. Now
we have a fairly unusual position that Black (in his enthusiasm for the
Bxc6+ lines) may have neglected to study. I have never had any
experience with this line but it looks to me that White’s pieces are placed
awkwardly and his influence on the centre is reduced because his d-pawn
is blocked.
Play could go 9...h6 10 Ne4 (one of the points of this 8 Qf3, 9 Bd3 line)
10...Nd5 and it is reckoned that Black has just about enough play for the
pawn.
However, it is understandable that some players are not altogether
file:///C|/Cafe/Tim/kibb.htm (4 of 13) [4/10/2001 9:12:14 AM]

The Kibitzer
convinced by this variation. Instead of Colman’s 8..Rb8, the new move
8...h6!? is gaining credence. Now White cannot answer 9 Bxc6+? Nxc6 10
Qxc6+ because after 10...Bd7 both Queen and Knight are en prise. Maybe
9 b4!? is possible, since after 9...Bxb4 10 Bxc6+ Nxdc6 11 Qxc6+ Bd7 12
Qc4 White threatens both the b4-Bishop and mate on f7. However, Black
has a simple answer in 12...Qe7 13 a3 Ba5 14 Ne4 Nxe4 15 Qxe4 0-0
when White has zero development and Black’s chances look good. This
analysis comes from Heyken and Fette but I imagine Spassky may have
been the first person to discover this.
Van der Wiel-Spassky, Reggio Emilia 1985-86, went instead 9 Ne4 and
after 9....Nd5 White’s pieces do not look well placed.
Personally as White, I prefer to stick to the main line (after 5...Na5 6 Bb5+
c6 7 dxc6 bxc6 ), namely:
8 Be2
Black invariably kicks the advanced Knight back now by
8...h6
when I play 9 Nf3
I know that Steinitz invented 9 Nh3!? and that Bobby Fischer revived it,
but when I play 4 Ng5 against the Two Knights I usually try to avoid
artificial moves. Only fluid moves that consistently develop pieces, create
threats or challenge the centre really fit into the picture as I see it. ( See
Diagram )
I have no experience with 9 Nh3 and
do not presume to know what is
Black’s best line. It’s tempting to chop
off the Knight on h3 at once but that is
probably what White wants you to do.
On the principle that “the threat is
stronger than the execution”, the move
Bxh3 is best postponed. 9...Bd6 is
possible but not as popular as 9...Bc5,
while even 9...Nb7 comes into
consideration. If you want to know
more about this line, study the famous
games Steinitz-Chigorin and
Fischer-Bisguier; the latter is in My Sixty Memorable Games .
The usual move 9 Nf3 threatens the black e-pawn so there follows:
9...e4 10 Ne5
I don’t mind my opponents making these supposedly tempo-gaining
moves like ...c6, ...h6 and ...e4 because all they are really doing is creating
holes and pushing my pieces (especially the Knight) to where they want to
go. Take a look at the diagram. ( See Diagram )
