C[Try to remember 
<b> <font color=red> <u> the principles of Go: </u> </font></b> 

1) <b> connect own - separate opponent's stones </b>  (or vice versa)

2) <b> NO unnecessary ataris </b> (e.g. when you do not capture s.th. afterwards, or you cannot properly justify yourself why you're playing it

3) <b> think often in terms of miai </b> in fuseki, and in general (e.g. Life & Death)
<http://senseis.xmp.net/?Miai>
<http://senseis.xmp.net/?MiaiStrategy>, with other words,
- <b> keep flexible </b> <http://senseis.xmp.net/?Flexibility>

4) <u> Opening to Middle Game </u>:
<font color=red> think every move about the 4 Questions </font> :
<b>Do you have a weak group? </b>
If yes, reinforce it. 
<b>Does your opponent have a weak group? </b>
<i>If yes, plan to attack it. </i>

<b>Can you make a big territorial move? </b>
<i>If yes, do it. </i>
<b>Could your opponent make a big territorial move or does s/he have a big territory? </b>
<i>Try to prevent, destroy or reduce it with appropriate measures. </i>

<http://senseis.xmp.net/?StrategyForBeginners4Questions>

5) <b> Play Sente moves - think in terms of Sente! </b>
<http://senseis.xmp.net/?Sente>

etc. etc., that seems enough for the beginning.
If you adopt to these concepts, I am happy to lose with 100 points. Really!
It would indicate that I taught you something.
(Once you're 5 dan I could learn from you)

Have a nice game!]

C[good placement (b12) - dangerous!

Another reason is that there was possible the so-called stone-tower-tesuji something like this: 
<http://senseis.xmp.net/?TwoStoneEdgeSqueeze>

Would have been nice to finish-off the corner with dessert! (Only works if black want to resist fully - deep dissappointment for white if not - like you did!)

;W[eo]
C["...cut to pieces!..." 
"Atari, atari - vulgar play" I prayed several times during our games and in the course.

It strengthens the opponent (white).

When giving atari, you must know exactly why!
The first principle should be to 
- i)  connect own stones
- ii) disconnect other stones.

The atari does not help i) for you and destroys ii). It was not possible to avoid a (slight) separation by white, but black could have gotten a better exchange than that. 

But, o.k.  it's not over yet.]
;B[fk]
;W[ek]
C["I didnt want you to be able to play We7 after Bf9" Bf9 is a nice shape move - bravo!

However,
White would never do that! (play We7):

1st, because We7 is atari! 
(Joking, but it serves no purpose to play atari for the sake of it)

2nd: it (We7) doesn't serve any of the principles of Go, numbered i) and ii) above.]
;B[fl]
C[I see now I didnt need to play e6. At the very best it removes a Ko threat!]
;W[fj]
C["... it removes a Ko threat!" from Black's options!

Worse, it removes the possibility to capture the bcd5/d6-stones, which could have been later a nice 8-point endgame, or now the ...

Try to remember - and apply - the proverb about ataris.]
;B[gj]
C[I always remember the proverb, but somehow I always see a reason to play it. Here I wish to do some cutting! My aim is either to link my stones to the centre or cut and kill your lower group. The key point being j6. If you join your f10 stone, I will play h9 etc.]

C[Live and let live is often the devise.

Now the going gets rough (for both?)]

C[I lose nerves and chicken out.
We4 as a ko threat might not work,
if black calmly finishes of the central ko,
We3 , whereopun black threatens to live whith the corner and creates some liberties
and eventually  cuts at j6 (after winning the ko, black has the liberties to do so).

White would be left shattered 
1. lost the ko
2. the L3/4/5-group is cut off
3 the bcdefg5-group is dead.

Even if black was answering the ko threat We4, black could play more threats Bj18 or/and! Bk19
, hence white would be in the same position as now (losing something on top) but really having no threat left.

Sometimes it's better to finish-off a ko early (immedeately: e.g. in the beginning (proverb))]

C[After much thought, I opted to protect my middle groups cutting points.

I was also thinking about playing Bm13, but I thought it too risky for my central group.

With this move I hope to combine pressure on your upper group with defence of my middle group]
;W[jh]
C[All your considerations are very good and correct! Very good!

The conclusion however, the move , is not 100% correct.
The shape move here would been more this very k12 white is playing now,
either immedeatley or with a preparation before.

I'll telly you more somewhat later.]
;B[ih]
C[I considered Bk12 too of course, but I felt that Bl12 protected the cut also and enabled more play in the centre.]
;W[jg]
C[BL12 protected the cut too,
but gave white much more leverage, 
i.e. destroying black's eye shape, WHILE preserving white's eye shape (L15).

Therewith, the good shape BL12, because not being the best one (BK12)
 enabled LESS play in the centre (for black).

BK12 had enabled black quite much for an eye and the option to destroy white's eye L15 without remorse (because the cut is protected).

A higher level strategy might sometimes even be:
not to worry about the cut, abandon the black H11/12 stones and purely go for attack on the white group. (White does not need, therefore not want to capture the H11/12 stones, because the big white center group is clearly alive with 6 eyes and 40 points.)

I did not want to tell you this some moves earlier, because you might have attacked my eye then - outch!]

;B[lj]
;W[mj]
C[In for some fun?

I don't know whether it's good or too agressive.]
;B[mi]
C[lets go!]
;W[ki]
C[White would find black's connection BL11 more troublesome/frightening, because it creates B-liberties and connection problems for white.]
;B[lk]
;W[nc]
C[Brrgghhh!
That's empty triangle!!

How could you?

(at best it can serve as bad example -
hopefully its weaknesses can be exploited later)

If you want to play in that direction,
Bm8 makes good shape, because it is the 
protective "tiger mouth" before or after the black atari on white stone N10.

If white reacts with the attached stone
(he should perhaps/rather not),
then jump/attachment m8 creates the "driving tesuji" <http://senseis.xmp.net/?DrivingTesuji> last diagram or 
<http://www.european-go.org/magazine/articles/english/01-10-99-go-skills1.html>, usually more stylish then a blunt atari (which sometimes, after all IS necessary). 

Other ideas could have been ... (I'll tell later when we finished in this area here)]

C[retreat...]
;B[oe]
C[I couldnt decide which was better, Bp15 or p14. I gues p14 is better shape but p15 is more direct]
;W[ng]
C[Both have their merits here.
Actually your played move looks more stylish to me. P14 looks more like a move which will end up in damezumari problems (lack of liberties)
<http://senseis.xmp.net/?Damezumari>

P15 is more like "capturing through a ko" and obeys more to the principle "If you can capture stones by taking them off the board - Do so"
(they cannot be utilized anymore by the opponent and give eyes and connection)]

C["Where?"
 I found the connection/separation issue at L15 quite important (more than p17; There was no actual threat in the upper right black corner.
).

If black had taken that point L15 in sente, it would have made all previous white moves meaningless.

But still white is in heavy damezumari and is on the retreat.]

C["I'm surprised you only commented about my bad shaped Bq5 now. I thought it was better than Bp5 because of possible double ataris with Wr5. Now here is the move I have been wanting to play for a while....."

You're right that Bp5 would have been worse.
If black could not remove the double-atari threat in good shape, perhaps playing completely elsewhere is also an option? White does not need to capture any of these stones for living, perhaps it's not so urgent then.]

C[White could go for all stones by playing Ws8.
This would result in ko with many internal ko-threats for black. The lower right white corner group would be cut of and either had to live, win the ko fight and have enough liberties or capture the 3 black stones qr4q5.

Although white is convinced that this ko fight could objectively be ended in some beneficial way it is safer to go this safe way in the game.

White therewith follows the strategy proverb:

C["Yes, it was a good game. A pity I lost so many groups! Thanks for the lesson" 

No points in seki - hence I connect in order to avoid rule questions.
We will go over this game once again and I'll show you how you could have played better, separate white, connect your stones, survive yourself or kill white.

Many of these issues - perhaps all - relate to simple shape questions, as the basis of all moves.

It is a nicely taught lesson (it will stick) that an empty triangle (m9) must be avoided in all cases (except in L&D for killing or making seki, e.g. Wc2). The empty triangle m9 also contributed to the defeat of the lower right black group(s).

When we go over this game, we could also try to analyze,
<ul>
<li> which stones are important
<li> which stones can/have to be sacrificed
<li> how important is sente, kikashi/aji-keshi in Life & Death struggles 
<li> not to play ataris (they waste ko threats)
<li> not to play empty triangles
<li> how to think in terms of balance, e.g. furikawari (exchange of s.th.) 
- opponent threatens to destroy some territory, and if you defend it becomes to small?
- think of a counter strategy, e.g. threatening to destroy opponent's territory (you tenuki from your own territory and therewith take sente for another situation)
<li>  to win with 1 point is enough
<li> in a high handicap game, simply keep all your black stones connected in good shape (one-point jumps) and you play well and win.

</ul>
Now we pass again twice and count.]
