Riga Variation #2
The Riga Variation in the Open Ruy Lopez (1 e4 e5 2 Nf3 Nc6 3 Bb5 a6 4 Ba4 Nf6 5 0-0 Nxe4 6 d4 exd4) was first played during a correspondence match in 1907 between the two cities of Berlin and Riga - and despite many believing it is ultimately unsound, its reputation is better than once thought and new discoveries in it were revealed in NIC YearBook 85 by Correspondence GM Peter Boll. The Riga variation is exciting and often leads to many wild sacrificial gambits galore, where, if White is unsure of what is going on, can easily lead to many a Black quick wins.
