Tesuji from amateur Games 5
This example is from an 8d (White) vs 7d (Black) game on KGS, played on 2 January 2006.
Note: this is a difficult position. My daughter and I spent a very enjoyable period last night examining what we believe to be all the possibilites. There is much here to consider. High dan level reading and creativity (to see various moves) are required.
