[Event "Import"] [Site "https://lichess.org/0erv45Ek"] [Date "2024.01.08"] [Result "*"] [TimeControl "-"] [Termination "Unterminated"] [Variant "Standard"] [ECO "B10"] [Opening "Caro-Kann Defense"] [Annotator "https://lichess.org/@/alanthejudoka"] [Source "https://lichess.org/study/UXe68SVo/JAEiGHzx"] [Orientation "white"] 1. e4 c6 2. Ne2 { already here I was planning to play 3. e5 and not to allow a pin of the knight } 2... d5 3. e5 Bf5 4. Nd4 Bg6 { before playing e6 I want to weaken b1-h7 diagonal } 5. h4 h6 6. h5 Bh7 7. e6 { And here is the e6-pattern! – see the picture above } 7... Nf6 8. Qe2 Qd6 9. d3 Na6 10. g3 fxe6 11. Bf4 Qd7 12. Bh3 { Notice that White is not obliged to take a pawn back immediately. One of the ideas of the e6-pawn sacrifice is to constrain Black globally and to capture a black pawn by most effective way } 12... Bf5 13. g4 Bh7 14. Nxe6 { here I had calculated a variant when I could win a queen for three pieces. 14. g5 hxg5 15. Nxe6 gxf4 16. Nxg7 Bxg7 17. Bxd7 Kxd7 but Black is OK in result of it } 14... d4 15. g5 Qd5 { Only move! By the previous and this move Sujia executes her best defense! } 16. O-O { it is probably better 16. Rg1 with an idea to take on g5 by the rook but I was not sure at the time of play } 16... hxg5 17. Nxg5 Bg8 18. c4 { this and the next move are good since White has to secure for his light-square bishop f5-square } 18... Qa5 19. Bd2 Qb6 20. Bf5 { Now if Black takes 20. Qxb2 then White gives a perpetual check by 21. Bg6 and 22. Bf5 since the black king cannot step on a dark square due to Ba5. Having made my last move I offered Sujia a draw which she accepted. Probably earlier in a game I could get more pluses from e6-pawn but Black defended well. Draw! } *
