Ranginduck (b) vs. Tonkla (w)… w +5.5 (komi: 6.5, playtime: 30 min + 5×30 byo-yomi)
This game was played between two SDKs (5k) in 2009 on KGS… an interesting SanRensei opening played by white and black here answered with P4 – R4 for bottom right corner instead of Q4.
White traditionally attacked black’s top right corner and used the pincer on right side (R14) to run out. – It shows black’s weakness in reading deeply which gave white the chance to limit black’s extension (invasion) down to one single point (J13) …. white’s base on right side and playing back isolated black by playing L17 but failed to kill its group completly.
Untypically the defensive move 54 by white on C7 which gave black more space to expand into white’s moyo with K13… as a better option I would see F5 to extend the centre oriented moyo with two wings.
It was a close win for white with 5.5 points instead black had played first the centre stone (K10).
