If you consider that the position is roughly equal, then there has to be some merit in making Black think from move 5, rather than being able to fluster his opponent with loads of memorized lines. If nothing else White should be ahead on the clock after the opening. } ( { Instead, } 6.Qe2 { is the tricky reply, hoping for the Keres's trap of Nd6 checkmate; for example, } ) 6...Nxe4 7.Qxe4 Qa5+ ( { Alternatively Black can play } 7...Nf6 { , when } 8.Bxf6 gxf6 9.Bc4 Qa5+ 10.c3 Qf5 11.Qxf5 ( 11.Qe2 { is also possible, just maintaining the tension } ) 11...Bxf5 12.Ne2 { led to an equal ending in S.Gregory-T.Dickinson, British League 2006. } ) 8.Bd2 Qb6 9.O-O-O Nf6 10.Qe5 Be6 { The grandmaster is oblivious to the danger and concentrates merely on developing his queenside. After all, in standard lines of the Caro-Kann the tricks are well known, but in this less familiar position Black suddenly goes horribly wrong. } {#r} 1-0
