Train this openingAbout this opening
Black grabs kingside space on move one and plays for an attack, at the cost of weakening the diagonal that runs at the black king. That weakness is permanent, and it is the first thing to look at. c4 is the most played move here, taking queenside space and getting on with a normal game. g3 is the most testing plan, because putting your bishop on the long diagonal aims it straight through the hole Black has just created. Look at the scores: g3 does better than the popular c4, which tells you the fianchetto is the more accurate way to punish the setup.
Plans
- Play g3 and put the bishop on the diagonal Black weakened.
- Play c4 to take queenside space and develop normally.
- Aim at the weak light squares near the black king.
- Avoid opening the kingside for Black, which helps the attack.
Where the pieces belong
- Bishop: g2, pointed through the hole in Black's kingside
- Pawn: c4, queenside space
- Knight: c3, supporting a central break
- Pawn: d4, the center already held
- Queen: b3 or c2, adding to the long diagonal pressure
Black attacks on the kingside, you play in the center and on the light squares. Opening the center is the standard antidote, because it cuts the attack off from support.
