I have posted The Complete Caveman Caro-Kann (download PGN) analyzing 1.e4 c6 2.d4 d5 3.e5 Bf5 4.h4 h5 5.Bg5, about which I have written several articles over the years. This latest piece offers a complete overview of the system after 5.Bg5 and features annotations by Angus French of his great win with the line at the London Chess Classic Open (which was published in IM Malcolm Pein's column in The Telegraph). If time allows, I will eventually offer up a complete repertoire for White, including interesting approaches against the topical 3...c5 and alternatives at move four.
I have carried the analysis as deeply as possible, but there are still some positions that are quite unclear, where "White has compensation" is all that can reasonably be claimed. The complexity of the situation will definitely favor the well-prepared player and computers will offer no easy answers to either side, even in correspondence. In this way the opening resembles the complex lines of the Botvinnik Semi-Slav and the King's Indian Defense and represents a very interesting challenge for analysts and players alike.
One thing is certain to me now: White is definitely better if Black goes after the Rook by 5...Qb6 6.Bd3 Bxd3 7.Qxd3 Qxb2? 8.e6! This is a common misstep among players who have not seen this line before (and who therefore assume White has simply lost his mind).
|Position after 7...Qxb2? 8.e6!|
The most complex play results not from grabbing the Rook in the corner but instead from swiping the d-pawn right in the center of the board with 6.Bd3 Qxd4!? 7.Nf3 (Black can meet 7.Bxf5? with 7...Qxe5+ winning back the Bishop) and now 7...Qg4! -- a variation that I did not even consider in my initial analysis.

A more strategic choice is to decline the gambit with 5...Qb6 6.Bd3 Bxd3 7.Qxd3 e6, after which Black should prefer a quick c5! over Anand's idea of Qa6 offering the trade of queens, which White can exploit or even accept with some advantage. Note, for example, that White can meet Anand's 7...Qa6 (played before White is ready to block the diagonal with c4) with 8.Qh3! e6 9.Nc3 transposing to our main game in the 8.Nc3 which looked very good for White. And 8.Qxa6!? Nxa6 9.e6!? should also favor White.
After 5...Qb6 6.Bd3 Bxd3 7.Qxd3 e6, the chief question is whether to play 8.Nd2 (which leaves open the option of a quick c4 advance) or 8.Nc3 (where White focuses on speedy development and a potential piece breakthrough). In practice, 8.Nd2 has proven more popular, but White needs to think about how to meet the immediate 8...c5! -- when best must be to fight fire with fire by playing 9.c4! The resulting play will emphasize White's lead in development.

1.e4 c6 2.d4 d5 3.e5 Bf5 4.h4 h5 5.Bg5 Qb6 6.Bd3 Bxd3 7.Qxd3 e6 8.Nd2 c5 9.c4 Ne7 10.Ne2 Nd7 11.0–0 cxd4 12.cxd5 Nxd5 13.Nc4 Qc7 14.Rac1 Nxe5 15.Nxe5 1–0While 8.Nd2 is attractive, my personal preference is for the less common 8.Nc3 (not considered by Lukacs and Hazai in their ground-breaking article in NIC Yearbook #100), which can be quite dangerous for Black unless he immediately challenges the center with 8...c5!

In posting my analysis online for free, I hope to encourage more games and analysis that should eventually yield a more complete understanding of this fascinating line. I welcome games and new ideas from my readers.
