This is another game Bill Brydon has played against his 
Vietnamese teacher Lo Ban in July 1995. Thanks again to
Bill for providing the game.

1. C2.5 C2.5
2. H2+3 H8+7
3. R1+1 
Not a mistake, but a bit uncommon, 3. R1.2 is seen more
often. One weakness of Black's opening is his left horse,
thus 3.R1.2 followed by R2+6 is trying to exploit this
weakness.

3. ...  H2+3
4. H8+9?
After this move Red's central pawn is a potential weakness.
After Black has finished the development of his pieces, he
might attack the central pawn with H7+6 or with C8+4. I'd prefer
4.H8+7, e.g. 4.H8+7 R1.2 5.R9.8 R2+6 6.C8.9 R2.3 7.R8+2 R9.8
8.C9-1 with the option C9.7. Red might as well consider 4.P3+1
to restrict the activity of Black's left horse, but after 
4.P3+1 R1.2 5.H8+7 R2+5 Black's rook becomes quite active. 

4. ...  R1.2
5. C8.7 P7+1
6. R1.6
With 6. R1.4 Red can avoid an immediate 6. ... H7+6. Even 6.R9.8
night be an option in this position, although Red looses a move
after 6.R9.8 R2+9 7.H9-8. However, later on Red can play C7+4
attacking the elephant followed by H8+7.  

6. ...  H7+6
7. R6+4?
Although seemingly winning a tempo by attacking the horse this
is not a good move. Black anyway wanted to capture the pawn and
after the exchange of the horses Red's rook position is bad.
Again 7.R9.8 is an alternative, but Black already has the superior
position. 7.A6+5 is another option.

7. ...  H6+5
8. H3+5 C5+4
9. A6+5 E7+5
10.P7+1 A6+5
11.R6-2 
If Red idles, Black will start a dangerous attack with R9.6 and C8+7.
Thus, it's correct that Red tries to ease the pressure on the central
file. However, the position will become quite complicated and full of
tactical motives.

11. ... C8+4
12.C7+1?
Now Black could get a passed pawn. Better for Red is 12.R9.8, after e.g.
12.R9.8 R2+1 13.H9-8 Red may get the chance to play H8+7 later on. Of
cause, Red still would have been in a difficult position after 12.R9.8
but the chances after 12.C7+1 are even worse. 

12. ... R2+6
Black could also have played 12. ... C5.3, e.g. 13.P3+1 R9.8 14.C5.2 C8.5 
15.R6.5 R8+7 16.H9+7 P7+1. 

13.R9.8 R2.1
14.R6+3
Red might also consider 14.R6+5

14. ... R9.6
15.P7+1?
Red underestimates Black's attack. 15.K5.6 was mandatory, although it probably
won't stop Black's attack, but it will be more complicated for Black after e.g.
15.K5.6 C8+3 16.C5.4 

15. ... C8+3
16.K5.6 C5+2
17.P7+1 
17.C5+1 would have offered tougher resistance, but Black's attack is too
strong, e.g. 17.C5+1 R6+9 18.K6+1 C5.7! 19.C5.9? (or 19.K6.5 K5.6)
R6-1 20.K6+1 C8-2

17. ... R6+9
18.K6+1 C5.9
18. ... C5.7 would have been even better.

19.P7+1(?)
Red allows the immediate checkmate, since he has no effective defence. To
hold a bit longer, Red should have tried 19.C5+1, but the position is
hopeless for Red.

19. ... R6.4
20.K6.5 C8-1 checkmate


Summary
Red's opening is quite unambitious. Even worse, he allows Black
to attack the weak central pawn and doesn't have any compensation. The
co-ordination of Red's pieces isn't good. Thus, Black's attack becomes
stronger and stronger. Red misses some chances to offer tougher resista
nce.  

1. C2.5 C8.5
2. H8+7 H8+7
3. H2+3 R9.8
4. R1+1 H2+3
5. R1.6 R1+1
This move is not treated in my opening books, they only
mention 5. ... R8+4 and 5. ... C2+2. Probably, it's an
unaccuracy from the view point of top players. However,
it's a natural move to develop the rook, I don't want to
mark it as a serious error. Black has to be aware, that
Red can play R6+5 in this line and he should always have
a plan to cope with this.

6. P7+1 P7+1
7. R6+5 H7+6?
This is not the correct defence. Black had two better
alternatives: 7. ...C2+4, since 8.R6.7 C2.3 is good for
Black or 7. ... C5.6 8.R6.7 E7+5, although Red will have
better chances after 9.H7+6. 

8. R6.7 H3-5(?)
This allows a deadly pin on the central file. There are
opening lines, in which it is good to play a horse to
the palace center. However, such a move should also be looked
at with much care. Here, Red can take the central pawn and
it will be almost impossible to release a pin. Red will
easily develop mate threats. It's not easy to give a good
alternative after Black's mistake at move 7. Probably Black
has to try 8. ... R1.3 and must hope that Red doesn't find
the best moves for his attack. After 8. ... H3-5 Red's task
is just too easy.

9. C5+4 R8+6?
There is no time for an attack against Red's right horse. Red's
mate threats are very serious, Black has to find a way to release
the pin on the central file, although this is very difficult.
A possible attempt is 9. ... R8+4 10.R9+1 H6-7 but Red can protect
the cannon with 11.C8+4. Later on Black may be forced to sacrifice
the exchange to release the pin. Another alternative is 9. ... R1.4
to protect the weak right advisor. 9. ... C2+4 might also be
considered, since Black might continue with R8+4 and H6-7 avoiding
Red's C8+4. However, Red can play 10. C5-1 Whatever Black tries, 
he can only hope that Red errs in his attack.

10.R9+1 C2+4?
Too late, Black has to play 10. ... R1.4 or 10. ... H6-7 11.C5-1 R1.4

11.R9.6 C2.3?
To avoid the immediate checkmate, Black has to try 11. R1-1 

12.C8+7
The game is over, there is no defence against the checkmate.

12. ...  C3.4
13. R6+2 H6-4
14. R6+3 R1.4
15. R6+2 R8.7
16. R6+1 checkmate

Summary
Two serious errors at moves 7 and 8 allowed a deadly pin
on the central file leaving Black without sufficient defence.  

1. C2.5 H8+7
2. H2+3 R9.8
3. R1.2 C8+4
4. H8+7 C2.5
5. A6+5?
This is an unnecessary precaution. Red should continue
to develop his pieces. The most common move is 5. P3+1,
since 5. ... C8.7 is not dangerous for Red. Other alternatives
are 5. P7+1, 5.R9.8 or 5.R9+1. Probably Red was fearing
5. ... C8.5 6.H7+5 C5+4, but after 7.H3+5! R8+9 8.H5-3 E3+5
9.H3-2 Red has gained a piece. 

5. ...  P3+1
6. C8+5? 
With this move Red wants to exchange a cannon pair,
a known plan for Red in this opening. However, it seems
that this plan is not so good any more after Red's 5.A6+5.
Red will have problems with the development of his right
side. Thus, exchange of pieces at his left side will
yield a position where Black's pieces are more active. 
Altnernatives to be considered for Red are 6.P3+1, 6.R9.8 followed
by 7.C8.9 or even 6.C8+6 and 6.C8+2.

6. ...  H2+3
7. C8.5 E3+5
8. R9.8 R1.2
9. R8+9 H3-2
10. P3+1 C8.7
11. E3+1 
Typical reaction of unexperienced players. Black's potential threat
C7+3 may look frightening, but there is no immediate threat and it's
usually not a good idea to voluntarily remove the elephant from the 
central files. However, it's difficult to find satisfying alternatives.
Red might consider 11.P5+1 with the idea 11. ... H2+3 12.P5+1 P5+1
13.H7+5 or 11.C5.6 followed by 12.E3+5. There is no doubt that Black's
position is clearly better in all these lines. 

11. ...  R8+9
12. H3-2 C7.3
13. E7+9? 
It looks natural, to move the attacked elephant and to prevent Black's
pawn from crossing the river. However, after this move both elephants
are positioned on rook files and can't defend the center. Red should
have considered to sacrifice his elephant e.g. with 13.H2+3. In this
way Red might have the chance to get some compensation by activating
his pieces, e.g. 13.H2+3 C3+3 14.H7+6 or 13.H2+3 P3+1 14.P5+1. Again,
Black has advantage in all these lines, but Red will be without any
chances if he tries to rely on pure passive defence.

13. ...  H2+3
14. H2+3 P7+1
15. P3+1 E5+7
16. H3+4?
This looks like an active move but it doesn't help to restrict Black's
left horse which will become active very soon. 16.H3+2 would prevent
16. H7+6 and was probably a better choice. 

16. ...  H7+6
17. H7-6 
Not an attractive move, but Red is already in deep trouble. Since the
central cannon is not protected (both elephants are far away!) Red had
to face the threat H6+4. Furthermore, even with the cannon protected,
H6+4 would be a serious threat, since Black might want to exchange the
cannon against one of his horses. In an endgame, horse and cannon are
usually stronger than two horses (or two cannons). Combined with the
pawn plus for Black such an endgame would be almost a clear win for Black.
Thus, the alternative 17.E1-3 H6+4 would not be much better.

17. ...  H6+4
18. C5.3 E-+5
19. P1+1 C3.2
Again, it can be seen that that Red's elephants are awkwardly positioned,
Red can't do much against 20. ... P3+1

20. C3.8 P3+1
21. E1+3(?)
Red tries to bring his elephant back to the center, but it's too late. He has
to try to stop the further advance of Black's passed pawn. 21.H6+5 would offer
stronger resistance, however, Red's chances are quite dim. 

21. ...  P3+1
22. P5+1 P3+1
23. C8-2 C2.5
24. E3-5 P3.4
25. C8+7? 
This cannon has to defend Red's king and has no time to attack.  25.E9+7 or
25.H6+8 are better alternatives, but in practice as hopeless as the text move.

25. ...  H4+2
26. H6+8 H2+3
27. K5.6 C5.4 checkmate

Summary
Early in the opening Red was too cautious by playing unnecessisarily
the time loosing move A6+5. Later on, he chose C8+5 followed by C8.5 allowing
the exchange of a cannon pair. This yielded a position with more active pieces
for Black. In this adverse situation Red tried a quite passive defence without
any counter chances.
