Jobava Attack vs the Grünfeld (Part 3)
This week I want to look at when Black doesn't castle, but plays 5...c5 / h5 / c6 / a6 etc.
1) Black tries to strike back against the White centre with 5...c5:
With c5 Black is permanently weakening the b5 square. Thus, you play 6. Nb5:
2) Black tries to stop h5 by playing 5...h5 himself:
Here there are different ways of going forward, but the most natural plan is to play 6. Be2, Nf3-Ne5, and f3, preparing the eventual g4. Other options are immediate Qd2 or Nge2 (so you can meet Bg4 with f3)
Let's start with a game by Baadur Jobava where he plays ...h5 in response to a combination of an earlier a6 and c6 (this game is also discussed here).
