Annotated Game #309: Don't assume the move is good

In this next tournament game, I make two bad assumptions about a move being good, and am punished for it. The first one is the e3-e4 break in the Stonewall Attack, which has to be more carefully prepared. The second one is the result of a hallucination and assuming that I could escape a pawn fork, which in fact I could not. For whatever reason I was more mentally tired than I should have been during the game, which led to the unfortunate short-circuiting of my thinking process.
