A bit of my impression of the first game. I suspected at the beginning that the handicap configuration is going to be difficult to apply, and the flow of the game seems to confirm it. Those ten stones surround 2 points of territory, so white has to try to make about 150 points from the influence provided from the strong group if it were to be comparable with a more normal 10-stone handicap configuration.
Another difficulty lies with the fact that about 95% of the value of the stones comes from the influence radiating from the centre, and therefore black has to be very active in making sure that the presence of those ten stones are clearly felt (e.g. through driving opponent groups into it when attacking or connecting own groups to it when being attacked). This places the onus to being mindful of full board considerations and not settling situations too early into white's hands (compared to a more traditional configuration where the more experienced place has to be careful and not settle the position too early, which will make the game very difficult on other areas of the board).
Oca, please let me know if you have any questions or would like any clarification on either the above or any of my comments made during the game.
Any comments or questions from observers would be greatly appreciated

Edit: by the way, yeah, "black" and "white" is quite confusing XD
