This is the analysis that the experts will be quoting tomorrow, and we have it exclusively here at Chess Life Online.

Nf3 Nc6 3. Bc4 Nf6 4. d3 Bc5 5. c3 d6 6. O-O O-O {After years of a German occupation of top chess, we are no longer in the grip of the Berliners, that have lost ground to the previously ridiculed Italians and their slow play. In other words: this is what everyone do these days. And after Ding Liren proved to be very solid in the Spanish, Alekseenko comes with nothing new.} 7. h3 h6 8. Re1 a5 9. b3 $146 {A novelty of no importance that quickly leads to a transposition. Generally I think it is an ugly move. But nothing is really bad here.} (9. Nbd2 {is the normal move.}) 9... Bb6 10. Nbd2 {[#]} Be6 $146 {By transposition, this is the real novelty.} (10... Ne7 11. d4 Ng6 12. Bf1 {Svidler – Nakamura, Interrnet Blitz 2020.}) (10... Re8 11. Bb5 Bd7 12.

Kh2 Rad8 16. Ba3 ( 16. Nxe5 $6 Nxe5 17. Rxe5 Nxc3 {is still equal in principle. But there is no point in taking on e5 if you do not at least get a pawn for it.}) 16... Rfe8 17. Nxe5 $5 (17. Rad1 {with complete equality existed too.}) 17... Nxe5 18. Rxe5 c6 $1 ({Another idea is} 18... Nf4 $5 19. Bxe6 Nxe6 20. Rd1 c5 $1 21. Re3 Bc7 $44 {with compensation.}) 19. Bxd5 {[#]} Rxd5 {There is nothing wrong with this move on principled grounds, but I do not see the point in exchanging pieces for Black, if you are trying to win.} (19... cxd5 $1 {was more natural to my taste.} 20.

But he has a pawn. The engine calls everything equal these days and suggest hilarious things like:} Bxh3 26. gxh3 Qc6+ 27. f3 $5 (27. Kg1 Qg6+ {satisfy the digital beast and its shameless longing for peace.}) 27... Qxf3+ 28. Rg2 Re6 29. Nh2 $1 {The only move.} Qxh3 30.

Kh1 Qh5 $6 {It seems clear to me that Ding here could not find a way to continue.} ({ I believe he should play something where the bishop ends up on c6, like} 24... b6 $5 {with the idea ...c5. The chances are about even. And in such a situation, being equal with an extra pawn is more enjoyable in my view.}) 25. Re3 $1 Qe5 26. Ng3 Qa1+ 27. Kh2 Qf6 ({I think White's advantage is very very tiny after} 27... Be5 $5 28. Be7 Rd7 29. Bc5 Bf4 {, where White is not able to stabilise his pieces yet.}) 28. Bb2 Qg6 {[#]} 29.

Qe2 $5 {looked nice as well.}) 31... b5 $5 {I am not sure eactly what the idea is here, except there is a need to do something.} (31... Bd7 $1 32. Re3 c5 {improving the bishop is the most logical as far as I am concerned. Black is fine.}) 32. Qe2 bxc4 33. bxc4 a4 34. Qe3 Qg5 $1 {With the white rook poorly placed, exchanging the queens is a reasonable proposition. And an opposite coloured bishop endgame is getting closer.} 35. Qe1 $1 Qg6 36. Qe3 Qg5 37. Qe1 Qg6 38. Qe2 a3 $1 {Fixing the a2-pawn on a light square.} 39. Bb4 {[#]} Rb8 ({Black has plenty of chances to draw this game. For example:} 39... Bxc4 $5 40. dxc4 Qb1+ 41. Be1 Rd1 42.

Nd4 {[#]} Be4 $2 {A serious tactical mistake, but probably what Ding had been planning all long. He spent 9 minutes on this move and saw no reason not to play it.} ({With normal play, like} 44...

Not just because it is missing the winning continuation, but also because there were plenty of moves that did not lose on the spot.} (47. Bb2 {is the most important move to consider. Ding had probably prepared:} c5 (47... Qf4 48. Nf3 Bxc3 49. Rxd8+ Kh7 50. Bxc3 {also gives White a winning position. The three pieces from the pick 'n mix are far stronger than the queen.}) 48. Nf3 $3 {Of course Alekseenko missed this basic tactic. Probably he was not emotionally prepared for tactical chances to arise and thus not looking for them. It is not much of an explanation, but it is the best I have.} Bxc3 (48... Rxd3 49. Qxe5 {also wins easily.}) 49. Rxd8+ Kh7 50. Ng5+ {[#] White wins.}) 47... Rb8 {Black is now winning.} 48. Bb4 {It is hard to grasp what Alekseenko was imagining. For example:} (48. Rd1 Rb1 49. Qd2 Bf4 {or 49...Qf4, and Black wins.}) 48... Rxb4 49. Qxb4 Qxd3 {[#] Black wins. White get to give a few revenge checks.} 50. Nf3 Qf1+ 51. Ng1 Bd4 52. Qb8+ Kh7 53. Qf4 Bxf2 54. Qf5+ Kh6 55. Qf4+ Kg6 56. Qg4+ Kf6 57. Qf4+ Ke6 58. Qe4+ Kd6 59. Qf4+ Kc5 60. Qe5+ Kxc4 61.
