Originally posted by Paul DiracIt does both, a fact that won't have escaped my opponent. As it turned out the g-file never needed to be occupied by a rook, and the fianchetto makes the rook less effective along that file. If the centre breaks up in a way that allows my bishop to give a check along the a2-g8 diagonal then there could be a way to exploit that that gets me something, so if the opportunity comes along he'd want to put his king on h8. The thing is that my last rook move (move 13) didn't really achieve anything (I thought I was being clever putting 'x-ray' pressure on his queen) so I'd presented him with a chance to make a free improvement.
AThousandYoung saw it as preparing for an offensive move with the rook, whereas you seem to be saying it was more a defensive move to tuck the king away.
If IronMan31 sees this, maybe he will enlighten us. 😕
Just remembered another possibility, 1... c6
I sometimes play this as I play the slav, so like to try and give my opponents the chance to play d4 (although they usually follow up with d3 🙁 ). It also gives possibilities for some sharp lines such as c4 c6 Nc3 d5 xd5 xd5 d4 e5!? or c4 c6 b3 d5 Nf3 xc4 xc4 e5!?
