We should have a segment here called "Losses", because most of the time I can learn more out of them. Before this win I lost two games to simple tactics. In both lost games I blundered a piece without noticing, that I could take a piece for free before that. This relies on my tunnel vision. In this Win I missed a tactic too and I lost my hard gathered advantage within one move.
Fortunately he blundered his bishop and I could win it.
