I strongly suggest the reading of a very old forum post https://www.chess.com/clubs/forum/view/greek-kia-series
it has a whole series of options that are frequent and excellent explanations of why certain moves are good and bad. I think the first set up you inquired about are in part 2
Hi All,
Hopefully this post will work out... I've not done many of this complexity (with embedded diagrams).
When I play experienced opponents, I seem to encounter the following lines. I'd like advice on how to handle them, if anyone cares to weigh in.
Line 1 - 1. Nf3 Nf6 2. g3 d5 3. Bg2 c6 4. O-O Bg4 5. d3 Nbd7 6. Nbd2 e5 7. e4 Bd6
How do you guys like to handle this (and why, so I understand the idea, not just the moves)? I find the B on g4 very annoying, but am not sure that h3 (seems frequently played, and a sometimes theme in the KIA) is wise here, or how to follow-up.
Line 2 - 1. Nf3 Nf6 2. g3 d5 3. Bg2 c6 4. O-O Nbd7 5. d3 e5 6. Nbd2 Bc5 7. e4 O-O
Likewise, how do you like to approach this? I find the B on c5 very annoying. 8 exd5 to open the game seems to have ok results? Or, (is this still KIA?) playing 6.c4 instead of Nbd2 also seems to work OK (in databases)?
