White: HikaruShindo (1590), Black: moonbus (1870), notes by moonbus
1... c6 2. d4 d5 3. e5
Caro-Kann Advance Variation. White usually enjoys a slight advantage in space; Black's position is usually slightly restricted but hard to crack open.
3... Bc8f5 4. Ng1f3 e6 5. Bf1e2
In earlier times, it was thought necessary to play the light-squared B to d3 and trade the good White B for the bad Black B. Nigel Short (vs Karpov) demonstrated that this line is also playable.
5... Nb8d7 6. O-O Ng8e7 7. Bc1g5 h6 8. Bg5h4 g5
White will find his dark-squared B poorly placed now, as it is hemmed in by the Black g and h pawns as well as his own e and d pawns. He might have done better to have exchanged it for the Black KN on e7 a move ago.
9. Bh4g3 Ne7g6
Targeting f4, which will prove to be the key to this opening.
Black has good play on the K-side, so White must make a counter-demonstration on the Q-side and try to break open the center.
This forces a critical weakness in the White K-position.
The h3 pawn will become a target in due course.
There is no point in ... h5-h4, forcing the White B back to h2; the White B is quite useless just where he is already. Black now clears d5, preparing a QN maneuver, ultimately heading for f4 via b6 and d5.
12. Be2xc4 Nd7b6 13. Bc4b3 Nb6d5 14. Nb1c3 Bf8h6
One precautionary move here, before ... Nd5-f4. Bh6 prevents White's natural developing move Rc1 (on pain of ... g4).
