It is known for dan players that they don't have a lot of problems with replaying their games out of memory, but for us mortable kyus it is different. For this reason many kyus use some tools to record their games. Today at the first day of the European Go Congress I have seen a lot of such tools (e.g. IPads, Nintendos, or paper kifus), even my opponent - a nice lady from Romania - had one. I tried several times to record tournament matches while playing, but always failed, so I liked the idea to memorize the kifu while playing. I've been struggling with memorizing for quite some time, but always lost track after a dozen or so moves. But this time it was different - for the first time ever - I can remember all 73 moves (well, that's not a lot, but still

). I have attached the SGF and enriched it with my thoughts that I had during the game. If someone wants to bother with looking over it, please leave some information where my comments went astray...
