Complicated Endgame Played Too Fast
Opening: A02: Opening: King's Gambit (Transposition)
Black falls into a trap in the opening and loses a pawn. He then questionably trades into an endgame but gets some play. Although lower rated, Black slowly outplays White and gets an advantage. White then has the option of trading into a very complicated king and pawn endgame. Instead of taking time to figure it out, both sides go headlong into the complications. However, once in the endgame, they decide not to calculate any of the complications and play quickly, amounting to host of missed opportunities. Black finally wins, but the instructive lines both sides made no attempt to calculate are the story.
