{One cannot say that Junior7 won this game, one must say that Hiarcs732 lost
this game due to his less accurate defence. But it was one of those games
where Junior7 with already two pawns behind got and realized some attacking
chances against the opposing king. Nicht Junior7 hat diese Partie gewonnen,
nein vielmehr hat Hiarcs732 dieses Spiel infolge ungenauer Verteidigung
verloren. Junior7 mit bereits 2 Bauern im Rueckstand erhielt erfolgreich
Angriff gegen den weissen Koenig.} 1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 c5 5. a3
