is a relatively easy Catalan for Black to 'huddle and survive'. The plus-side
being that after he does, he has a slightly better structure to try and work
with. The analogy to Karjakin's line in the 'Korchnoi-Karpov variation' is
obvious.}) 7... Bd7 8. Na3 cxd4 9. Naxc4 Be7 10. Qb3 Qc7 $1 {Now the main line

at least optimistic.} (10. a4 b6 11. Nf3 Bb7 12. O-O O-O {and Black need not

king, or the ...h4 break- but both are on the cards.} 23. Rhf1 {This move
tries to keep both rooks, with the idea of (at some distant moment) doubling
them on the c-file.} (23. Rhd1 Rd7 24. Nd4 Qg5 {will also swap off some rooks.}

popular line of the Catalan system. The idea is as obvious as it looks. White

this decision. Clearly his first choice would have been just to play Bd7 but
