9...c5

The 9...c5 is a rock solid variation. GM Timman went wrong when Adams pressured the kingside.

Queen's Indian Hybrid 7...Ne4(E13)

This game shows the advance of theory since IM Greet's Play the Queen's Indian(Everyman 2009).

I defended the Queen's Indian Hybrid in my last tournament with nothing but the most superficial knowledge but now the time has come for a serious upgrade.

Key Position
Here Greet gives 14...Qf6 and notes that 14...0-0 is 'playable looking'.

14.0-0

Here is the feature game where British GM Michael Adams plays 14...0-0 and the move has now become part of main Queen's Indian theory.
