It was back in the 1920s that the Russian master Benjamin Blumenfeld invented
his famous gambit 1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.d5 b5!?,
and to the present day the opening retains great popularity. Black plays
for the initiative and the win from the word go. We have a marvellous new
Fritztrainer by the very popular English chess trainer Andrew Martin, 4
hours 44 min of intense training with interactive video feedback.
