I have checked and added a few of my own lines. Kojima's comments are bracketed as applicable.} 1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. Nf3 dxc4 5. a4 Bf5 6. e3 e6 7. Bxc4 Bb4 8. O-O O-O 9. Qe2 Bg6 10.

Nbd7 {[#]} 11. Ne5 $6 { After this inaccurate move Black is able to resolve the central tension in a safe manner (Kojima)} (11. h3 {Computer's suggestion is a bit weird, but not quite clear to me how White should improve, perhaps Bd2 with Rac1}) 11... Nxe5 12. dxe5 Nd7 13. e4 Qe7 14. Bf4 a5 15. Qe3 h6 16. Na2 Nc5 $2 {I came up with a strategy of placing the bishop on c4 from Nd7-Nb6 and retreating to Bb4-Bc5, and touched the knight to point it, but the knight I placed on b6 was taken by the queen for free. ! It can't be helped that I touched the knight, so I have no choice but to point to the actual hand. (Kojima)} ({To illustrate, consider (Kojima)} 16... Bc5 17. Qg3 (17. Rxd7 Bxe3 18. Rxe7 Bxf4 19.

Rxb4 $2 Rxa6 $17 {The weak b-pawn may turn into a target}) 20... Rxa1+) 19. f3 Ng5 $6 $18 ({Probably this is better than what Kojima played} 19... Nc5 20. Rd6 Na6 21. Qb6 $16) 20. h4 $6 {This is the move he regretted after the match, and the knight wants to improve his position with g5-h7-f8, so the knight's drive back from h2-h4 ends up helping black. If White simply jumps in with 20. Rd6 , White will be able to advance the game advantageously by controlling the d-file even without any pawns. (Kojima)} (20. Rd6) 20... Nh7 21. Bg3 Rfc8 22. Qb6 Nf8 23. Rd6 c5 24. Qb5 Qc7 25. b3 h5 $1 { By replacing the knight with f8, we were able to prevent the rook from entering d7. After that, I think it would be good to have a chance for Bg6-Bf5, Nf8-Ng6 in the future, so I will increase the h-pawn. (Kojima)} 26. Kh2 Bf5 27. Rb6 Ra7 28. Rd1 Rca8 29. a6 $2 {Although we tried to improve our pieces, just when we thought we had reached a stalemate, our opponent made a crucial mistake. Having been hit by two rooks on the a pawn, he rushes forward with his pawns, but immediately after the a5 pawn is captured, he makes a counterattack to take b7. Don't worry about A5, 29. Bf4 would have been fine. (Kojima)} (29. Bf4) 29... bxa6 30. Qc6 a5 31. Ra1 Nd7 32. Qxc7 Rxc7 33. Rd6 Kf8 ({The endgame is 2 pawns up, and from here on, we need to think of a strategy to take advantage of the queen-side majority. In this version, I safely placed the king in the center.} 33... a4 $1 34. bxa4 Bc2 {was the quickest deciding factor. (Kojima)}) 34. Rad1 Ke7 35. Bb5 Nf8 36. Ba4 Rb8 37. Ra6 c4 $1 {a4 was stopped, but he came up with a strategy to push out the opposite c-pawn and made a decisive break. White must discard the bishop to stop the b pawn, which has become a passing pawn.

Bc5+ Ke8 {The black king looks a little dangerous, but the knight covers squares e7 and f8, and you can also secure squares f7-f6 to f7, so there is no problem. (Kojima)} 45. Bd6 f6 46. Ra8+ Kf7 47.
