Apertura Benko por Pal Benko
Translation to English:
The Benko Opening (ECO A00) only seeks the fianchetto of the bishop on g2. It can lead to major openings where this fianchetto is useful, and it's like playing an Indian system with Black, but with White. Also, it reveals ahead of time where White is going to castle, so Black can launch an attack right away, given the weakness created on g3. It's Pal Benko's idea. It has the merit of surprise, which is not little. If you don't want to transpose to main lines, you have to play very well to avoid falling into lower lines.
