00:00Exclusively until 1977, when I switched to D4, and then, again, almost exclusively until I played Antelikarpov, I sticked with D4.
00:13And I have to say that I believe that D4 was even more aggressive move, because I actually found ways of playing fairly aggressive openings.
00:22Even, for instance, against the Queen's Gambit.
00:30So I managed to work out quite an aggressive system, taking one of six, playing E3, and then playing Queen D2, and then Longcastle, or Queen C2 and Longcastle.
00:42Now we all know how to equalize.
00:44There are many ways for black to equalize, but at the time, it was quite a revelation, and it was difficult for strong players to resist the pressure.
00:55I also played D4, and what I liked was the so-called Petrosian system.
01:00In the Ninsa Indian, playing E3.
01:05It's quite amazing that's how this move, E3, helps you to fight for the central squares.
01:11Because at the end of the day, it looks like E3 is just a waste of time.
01:15That would be an instant reaction of Zygmuntar or any old classical player from the 9th century or the 20th century.
01:24But E3 prepares Knight C3 and preventing Bishop B4, pinning the Knight, and thus helping White to fight for the control of the central squares.
01:33So I remember that I've been promoting this idea of E3, saying this is the best way to fight for the center, and creating stronger position in the center, and you can have a powerful attack.
01:44I also remember that in late 70s, I was highly critical of Greenfield defense.
01:49Because for me, you know, playing D5 meant that after exchanger coin D5, playing E4, Knight C3, BC3, White had a pass pawn that should be promoted.
