Alexey Dreev Blackmar-Diemer

GM Alexey Dreev faced the Blackmar-Diemer Gambit in two hard fought games. Dreev is a great blitz player and one of best defenders in the world with Black.

The main game is a BDG Gunderam where both players were rated over 3000 on the Internet Chess Club in 2004. That's way up there. "Over-Rated" as White got a small edge after a wild opening. The game lasted until move 97 when Black resigned.

Dreev faced the BDG on March 18, 2017, in a blitz game vs "Alright2015". This time Black chose the very weak fourth move 4...e5?! White has sacrificed a pawn. From this position, White usually wins three pawns in a row. GM Dreev improved over the normal play. He lost only two pawns. Thus he went from up a pawn to down a pawn. But then Dreev outplayed his opponent and won in70 moves.
