Black is, objectively speaking, not lost out of the opening, but it's nevertheless clear that I had little real idea of what to do, making the position an uphill struggle both on the board and psychologically. Perhaps this is why Black misses several equalizing opportunities, most notably on moves 9 and 14. It's also worth noting that these moves would have required Black to recognize the need for more active play; Black by move 16 looks stuck in a passive, defensive mode.
This is also one of those games whose result can be largely explained by psychological factors. In this case, I felt like I was struggling the entire time and was lost from a certain point on (around move 19), which became a self-fulfilling prophecy. In fact, White misses a killer move (29. f6!) and Black equalizes immediately, finally being able to generate counterplay - if only he could recognize it. The crowning moment of the game is when White apparently picks up a rook due to a Black blunder, which led to my resignation before it occurred. However, the rook is in fact poisoned and its capture would lead to White being mated.
Moral of the story: remember why you shouldn't play certain opening moves; never resign without running at least one final calculation of the position.
