C[ojmarcin: So, time to summary. Look at connestions: black has two groups, one in center and top, second at the bottom. White is divided to 7 groups and one stone.
ojmarcin: Look at eyes. Each group needs two eyes. Both black groups have two eyes. None of white groups have two eyes. N9 is not an eye because of M10 black stone. 
ojmarcin: same for M1 and N2 - these are not eyes because of black stones at L2 and M3.
ojmarcin: you shoud avoid empty triangles, like L4 and C4 - they lead to trouble 
ojmarcin: a10 was on wrong side of black wall, it would be better to play g11 instead to create living shape, it means space for eyes
ojmarcin: e12 created another empty triangle, g11 would be better for creating eye space, but anyway after black g10 it would be hard to live with this group.
ojmarcin: l7 was again empty triangle. It would be better to sacrifise this two stones and play l9 and l11 to create living grup in top right corner
ojmarcin: we can play again, if you would like. :)
