!!! Warning !!! If my previous posting is rated as "PG13", then this 
one should definitely be "R".  Some extreme violent scenes are taken from 
the "Harlem Nights" movie , automobile trade wars, and the Korea War.
Considering some subjects in Vietnam War and some Mideast Wars are still 
too sensitive these days, I dare not to touch them here :-)

Number 2 golden rule is:

                "Ru Jie Yi Huan"

Ru4 = enter
Jie4 = boundary
Yi2 = should, ought to
Huan3 =  unhurried, slow

Obviously, the legend tried to tell us what we should take care when
entering opponent's territory. The key here is how to understand
the word "Huan". According to Modern Chinese dictionaries, "Huan" is 
related to "Man4" and "Chi2" suggesting "slow" and "unhurried" in English.
Therefore, a straight forward interpretation of this secret ancient code is:
       "Be unhurried to enter opponent's territory".
A more imaginative one (from Otake Hideo) is:
       "In opponent's sphere of influence,
        avoid sharp conflict, don't move too deep".

With this golden rule in mind, it's easy to understand why in Board 1 
that some players (White) choose positions around K15 
(or even G15 in some situation) to enter Black's territory.

These secret codes, although written for Go games, didn't mention any 
particular Go term. It looks like from an ancient philosopher or 
strategist rather than a Go player. So, if you think we should go deeper
and beyond Go games, let's bring up those bloody pictures in human 
history.

==================================================================
!!! Dangerous !!! Please fasten your safety belt.
==================================================================

Imagine at midnight, you are walking through a street in Harlem of Manhattan. 
You do what you normally do when entering other people's territory:
1. Get through it quickly. So --- make it fast.  2. Just in case, be prepared 
to leave something behind when asked by a friendly stranger and don't 
carry anything too heavy so that you cannot get away. So ---- make it light.
This bring up two new concepts --- "fast" and "light".

"fast" and "slow" (or unhurried?) are perhaps easy to understood.
"light" and "heavy" are just like the pair "thick" and "thin" (already 
discussed) often ignored us.  However, we, the go players, are not alone 
out there.  Remember? not long ago, Detroit was taken by total surprise
when ignoring "light" (and then perhaps "quality"). If that was an old story,
then check out the latest: while Acura is making it all-aluminum for
V6 NSX, Lexus is putting V8 into its SC400, and Chrysler is 
developing it's V12 Viper (a huge monster in the engin compartment). 
Automakers have not figured out what's the perfect combination of 
"fast" and "light".

An even more intriguing story is the Korea War. While one side was able to 
achieve "fast" by equipping high tech high geers the other side managed to be 
"light" by carrying AK47 and Rice only. The result: it turned out to be 
an even game according to what I read in North America. 
(BTW, you don't want to know what I read back in China, but one thing 
is true, the actual rifles used were much lighter and simpler than AK47, 
and even the rice carried were of a special kind named small rice.)

OK, I hope you are not confused yet and able to watch Board 2 clearly.

Board 2 is obtained after the sequence J16-K16-J14-H16-J12-K4-P2-O3-O2-N3-J10

Black's sequence J16-J14-J12-J10 is a perfect picture
for illustrating "fast" and "light". Actually, J16 is so light that
it is definitely something you can leave behind in this violent White street.

The initial stone placed at J16 is also picture perfect for illustrating 
"Ru Jie Yi Huan". Not only "unhurried" and "slow", J16 actually gives up 
the possibility to destroy White's area deep in North side. 

However,  it was the "slow" move at J16 which makes the later "fast" moves 
and "light" shape possible. It will result in a heavy group engulfed 
in the White sea if black rush deep into the north side in a hurry.
Often time, it's not important whether or not we can find two eyes 
in other people's territory. By getting out in a lightening
speed with a extremely light shape. Black has a much easier life 
and doesn't lose the control of the board to White.

This "R" rated article has finished. However, when I went back to 
read again an article by Otake Hideo before posting mine, I realized that 
I have to add an "X" rated postscript.

Postscript:

The Black in Board 2 is the Japanese legend Kitani Minoru 
(Famous Mu4 Gu3 Shi2 to Chinese) who together with Qing-Yuan Wu (Go Seigen) 
is believed to be the father of modern Fuseki theory (Bu Ju in Chinese).
When commenting on his teacher's game, Otake Hideo [9p] pointed out that 
"J16 appears to be too deep inside of White's territory at first look, but 
it's not an overplay considering White's weakness at F16". So, "unhurried",
"slow", "not too deep", or "Huan" in this particular board should be 
understood by taking F16 into consideration.

When commenting on black's shape in Board 2 after J10, "Black's shape
appears to be light and huan" said Otake Hideo. However, my understanding 
is that "Black's shape is light and fast" although it's resulted from the 
"huan" (slow, unhurryed) in the initial step at J16.
(Remember the Desert Storm? it took half year of planning and 30 days
of air bombardment --- slow and unhurried!, but only 24 hours once the
troop was moved in ---- fast! Also, remember the Over Lord 
in World War II? many people misunderstood "huan" as "no gut" before 
Normandy crossing).

Other similar comments about "Ru Jie Yi Huan" made by Otake Hideo 
also seemlying to suggest that he paid no much attention to the fact
that the Chinese characters "Ru" means "To enter" rather than "inside".
I wonder who likes to be "Huan" when he is already "inside" a street 
in Harlem of Manhattan.
 
I dare not to admit that there is an argument between Otake Hideo and someone
who he can easily give several stones. The problem here is likely
resulted from errors in Chinese-Japanese-Chinese translation.
