;B[qd]C[It's always fun to watch such games, but difficult to comment. There are so many fights!
I only played with Matthew Macfadyen before and I was suprised that another top master from UK has similar playing style (more common strategy in fuseki, but later as aggressive as Matthew)
Here in Russia we don't have such fighters. Our aggressive players like Ilya Shikshin or Oleg Mezhov are much more peaceful and usually they don't fight, if they see that they are ahead. Other top players in Russia like me or Alexey Lazarev try to play as peaceful as possible]

;W[cg]TR[ic]C[Now we can see that marked stone is in bad position. It's the main reason why attachment at D14 is bad]
