[center]WHITE[/center][center]West India Game: Tal-Indian Defense (Sämisch Opening)[/center][center]Position after 6...c7c5[/center]

• The most common move here is 6...e5, the King's Indian Defense.
• The text set up often -- usually, in fact -- called a King's Indian, but my staff and I believe that it makes a big difference whether Black advances his c-pawn or his e-pawn, enough so that one merits independence from the other.
• Therefore, Tal-Indian Defense shall not merely be a new name for the Modern Benoni, but any West India Game where Black's pawn pressure in the center is derived from the move ...c7c5 without playng ...e7e5.

• Hold out baits to entice the enemy. -- Sun Tzu, The Art of War
