shr0pshire: When Basman plays these obscure lines, he isn't counting on the openings to win the game for him, he is looking to bring his opponent into new terrain, and let his superior middle and endgame lead him. He has strong tactical and endgame skills that won a number of games for him against master (Fm Im and Gm) titled players.
Unfortunately I think that Basman is lost before move 21, and I don't think he played this opening as well as he could have. I think that Basman allows himself to get kicked around too much in the opening. I play the borg myself with good results, and there are a few things I would do differently.
4. .... Bg2!? this is more aggressive attacking the d4 pawn, and forcing white to solidify his forces early on. Black can follow that up with his next move with a c5, fighthing for the center, and strengthening his dark bishop diagonal.
7. ....e5 is a better move. Basman is allowing Bryson to get a stronghold in the center for too long. White's center with Bg4 allows the center to become too strong and overwhelming for black temporarily.
13. ... Nd7. Make this transpose into a quasi french. Let the bishops defend kingside, and let the knights go to the queenside.
Although Basman evens it up incredibly by move 38. Basman commits a critical error.
