 GoAhead 19k :  time limits 45min + 15min/25 byoyomi
 GoAhead 19k :  so far: ManyFaces - GoAhead :  1-2

GoAhead 19k :  the one-space low pincer (Wc7) seems to be MF's 
 GoAhead 19k :  most frequently played joseki against the low 4/3-kakari ...

GoAhead 19k :  again, the atempt to "punish" W's tenuki with Bc8

MF: both programs following joseki all the way.

GoAhead 19k :  ouch, ouch (c6, f6)

GoAhead 19k :  certainly not the proper move - W can still go for b5 
  GoAhead 19k :  to cause some trouble. But even if B catches the two 
  GoAhead 19k :  stones, he has invested two more moves, while W got 
  GoAhead 19k :  two important fuseki points (the triangles stones)

MF: strange move.  should be on the right side.

GoAhead 19k :  MF got the super-big point r11

GoAhead 19k :  p18 would be a nice invasion point for W

GoAhead 19k :  W invades this way - also possible of course

GoAhead 19k :  p16 bad move (r18!)

MF: and the response to this bad move is in the invasion pattern 
database.

GoAhead 19k :  easy invasion for W

GoAhead 19k :  W leads (GA's score W+8)

MF: w+8.5

The programs generally seem to agree on the score when the position 
is quiet.

GoAhead 19k :  B helps to build W´s mojo this way 
  GoAhead 19k :  W should just play q11

GoAhead 19k :  Sq11 big move

GoAhead 19k :  close game
 GoAhead 19k :  Wm10 big point

GoAhead 19k :  big point in reverse sente
  GoAhead 19k :  B should have got to play there!

GoAhead 19k :  the LL corner is big now, taking into account W´s aji b5

GoAhead 19k :  good - big.

GoAhead 19k :  ManyFaces challenges in this way

GoAhead 19k :  GoAhead defended the corner (presumably)

GoAhead 19k :  GA's score is W+5

MF: w+13.5

GoAhead 19k :  Bc2 important and sente

GoAhead 19k :  Well, kind of sente

GoAhead 19k :  GoAhead lost one move here.
 GoAhead 19k :  A center mojo will be build by Manyfaces
 GoAhead 19k :  GoAhead is pretty bad in avoiding this

GoAhead 19k :  good move, two directions

MF: strange move.  it's trying to cut off the last move.

GoAhead 19k :  ManyFaces starts a fight

GoAhead 19k :  hm - ManyFaces lost an important move here (Wa10)

GoAhead 19k :  GoAhead reduced W's center, I´m impressed!
 GoAhead 19k :  but W is leading anyway (W+16)

MF: w+16.5

GoAhead 19k :  close game now!

MF: good sequence by goahead

GoAhead 19k :  GA's score is B+1 now

MF: W+1.5.  white makes a small move

GoAhead 19k :  hm - was Be2 possible instead of Bc1?

GoAhead 19k :  interesting - W takes sente

GoAhead 19k :  ah - things heat up now - Wj10 turns g13 back into living

GoAhead 19k :  Wk9 instead of k6 seems more natural

MF: too greedy.  tyring to cut

GoAhead 19k :  nice defense by B

GoAhead 19k :  score is B+6

GoAhead 19k :  W doesn't like to be cut here - but the cut 
seems pretty meaningless

GoAhead 19k :  oh - too bad: Se10 was so natural ...

GoAhead 19k :  score is W+0

GoAhead 19k :  around o12 anybody?

GoAhead 19k :  fine!

GoAhead 19k :  W takes profit in the center

GoAhead 19k :  Bn10 bad yose move

GoAhead 19k :  close match!

GoAhead 19k :  yes - this is the move I feared!

GoAhead 19k :  This time, I think that both program have indeed 
  GoAhead 19k :  understood the L&D probelm in the corner 
  GoAhead 19k :  (hopefully, I'm right!)

GoAhead 19k :  GoAhead thinks, the corner is stable

MF: also.

GoAhead 19k :  GA's score B+3

MF: b+8.5

GoAhead 19k :  the last trouble ...

MF gives away a point

MF gives away another point.  No need to defend after opponent 
passes :)

Black wins by 11.5 points.

GoAhead 19k :  This was a close game. Both programs played carefully 
- as if they were impressed by the opponent's way of playing and fighting 
ability observed during the first 3 games of this match. 
ManyFaces profited by the "joseki" played in the LL corner, where 
B made some shape errors. ManyFaces also got an easy invasion at 
the upper side. Consequently, W took the lead by a few points in midgame. 
But I think the game was decided by yose considerations.  ManyFaces 
failed to take more profit in the LL corner. GoAhead managed to win a 
small tactical fight around g13. GoAhead was also able to reduce 
ManyFaces' center mojo to a tolerable size.  These small fights decided 
the game.

Total result of the lader match: ManyFaces - GoAhead : 1-3

The game is over.  Final score:
   White = 67 territory + 4 captures + 5.5 komi = 76.5
   Black = 76 territory + 12 captures = 88
Black wins by 11.5.
