Annotated Game #182: Remember that your king can move (and other board sight freeze-ups)

This short, rather sad second-round tournament game illustrates the title quite well.  An example of how not to play the English very effectively, plus I got flustered by my opponent's sudden tactical threat at the end.  I occasionally have these types of board sight / move choice failures, which typically fall into the categories of not seeing: 1) king moves while on the defense; 2) pawn advances; and 3) backwards moves.  What I believe is going on is that my brain assumes that the pieces involved are either static, or should move in a different direction (forwards, in the case of missed backwards moves).  These are all understandable failures due to mental bias, but they will hold my play back if I don't think more dynamically on a consistent basis.
