  Mateo: <Pawn and Two: White's last chance to hold the game was with 44. Bc2!! dxc2 (-.27) (18 ply)> Interesting but then what? I think Black can reach a Queen ending with good prospects of a win.

45. g6 Rg5! 46. Re1 Kb3 47. Kf7 Kb2 48. Ne4 Rg2 49. g7 c1Q 50. Rc1 Kc1 51. Nc3 Kc2 52. Ne4 c3 53. Kg5 c2 54. Ng5 Rg5 55. Kg5 c2 56. g8Q c1Q 57. Kf6 (only move) Qf4!.

Feb-27-06  ashalpha: I see, after 54.Qb7 Kc3 55. Qf3 Qd3 56.Qe5 will not work because when the queen is at b3, c3 comes with check. The problem there of course is that 56.Qe5 is not forced. There may be a refutation to 56.Qf2 but I guess I am too biased at holding the draw to see it. Any refutations to 56. Qf2?

  Pawn and Two: <ashalpha> If 54. Qb7+ Kc3 55. Qf3+ Qd3 56. Qf2 c1(Q) would be decisive.
Feb-27-06  ashalpha: pawn and two, sorry about that I just posted that without really looking at what I posted and left to go eat. I missed a whole series of moves on the line above. Let me see, the line would be something like this 54. Qb7 Kc3 55. Qf3+ Qd3 56. Qf4 Kb2 57.Qf2 not Qe5 since as you said it allows the Black Queen to maneuver to Qb3 with c3+. So on the previous post I meant 57.Qf2, not 56. Qf2. Sorry for the confusion.

  Pawn and Two: <Mateo> This is a very interesting ending. I believe 44. Bc2 was White's best chance, but apparently it does not save the day for White. However, I think there is an improvement in your line.

In your line there are a couple of typos. At move 53, you probably meant Kf6 for White and maybe Kb2 for Black, as you later have Black playing c2 on move 56.

The position you give after 57. Kf6 Qf4 is still very difficult. White has to play 58. Ke7 and then you would have a Queen + Pawn vs Queen ending.

Rueben Fine in Basic Chess Endings states that in endings of Queen + Pawn vs Queen that in general it is a draw unless the side with the Pawn has a BP or center P on the seventh supported by the King. He notes that in general it is impossible to advance a Pawn very far. The other side will keep on checking and when he runs out of checks will pin the Pawn.

However, I do think you are right that Black can win this game, but not by going into a Q+P vs Q ending.

I checked your variation using Fritz 9 and it provided some improvements. One of these was: 51.Nc3 e5!. With 51...e5, Black is clearly on the winning path.

  Pawn and Two: <ashalpha> If 54. Qb7+ Kc3 55. Qf3+ Qd3 56. Qf4 Kb2 57. Qf2 Kb1. It looks like the Pawn will Queen in this line also.

  Mateo: <Pawn and Two> <In your line there are a couple of typos. At move 53, you probably meant Kf6 for White and maybe Kb2 for Black, as you later have Black playing c2 on move 56.> You are right. My script was mistaken.

Please read: 45. g6 Rg5! 46. Re1 Kb3 47. Kf7 Kb2 48. Ne4 Rg2 49. g7 c1Q 50. Rc1 Kc1 51. Nc3 Kc2 52. Ne4 c3 53. Kf6 Kd3 54. Ng5 Rg5 55. Kg5 c2 56. g8Q c1Q 57. Kf6 (only move) Qf4!.

I will have a look tomorrow to your computer variation.

Feb-27-06  LancelotduLac: A gem of a game from Aronian, starting with an opening novelty that required very deep preparation, straight through into an imaginative and dynamic endgame. The position was very messy throughout, which is Aronian's style, dragging his opponent out of his comfort zone and slugging it out with bare fists. The evaluation wasn't clear until the end, but Bacrot certainly had his chances, for example move 37 (to be fair, Bacrot was in dire time trouble), he had 37.Rd1!, and now if ...d3 White has 38. Bxd3 cxd3, 39.h7 c2, 40.Ra1 and wins. But Aronian could have played differently before to avoid that, so it's not like there was a static evaluation throughout most of the game.

This variation does not mar the beauty of Aronian's win; on the contrary, it just makes it more "real." These kinds of slugfests that Aronian often aims for will, by their nature, offer mutual chances in a rollercoaster game -- but in the end the stronger, braver, and more creative player will come out on top. In yesterday's game against Bacrot, Aronian showcased those very qualities and was the deserving winner.

This is only his second closed supertournament, and if there were any doubts about him being unable to hold his own, he has dispelled those myths in Morelia. Aronian is here to stay, and I expect him to be one of the top 5 players in the world for a few years at least. World Champion someday? It seems too soon to make such pronouncements, but don't count him out...

  Mateo: <Pawn and Two> No doubt, your improvement gives a clear win for Black. So, after 45. g6 Rg5! 46. Re1 Kb3 47. Kf7 Kb2 48. Ne4 Rg2 49. g7 c1Q 50. Rc1 Kc1 51. Nc3 e5!, then if 52. Ne4 Kb2 53. Nc5 Kc2!, Black wins (but not 53... c3? 54. Nd3 Kb1 55. Ne5, draw).
Feb-28-06  euripides: <Rueben Fine in Basic Chess Endings states that in endings of Queen + Pawn vs Queen that in general it is a draw unless the side with the Pawn has a BP or center P on the seventh supported by the King. He notes that in general it is impossible to advance a Pawn very far. The other side will keep on checking and when he runs out of checks will pin the Pawn.> Computer analysis has changed the evaluation f this ending in favour of the side with the pawn. Acording to Mueller and Lamprecht, with a bishop's pawn or a central pawn, the defender needs to get his king in front of the pawn. With a knight's or rook's pawn, he can sometimes draw by putting his king in the opposite corner.

  Mateo: <LancelotduLac> <he had 37.Rd1!, and now if ...d3 White has 38. Bxd3 cxd3, 39.h7 c2, 40.Ra1 and wins.> The fact is that 37. Rd1 wins for White. Another variation after 37. Rd1 is 37... Rg3 38. Rd4 Kc6 39. Bg6 Nh6 40. Kh6 Kc5 41. Re4, and White wins.

  Mateo: 36... c4 leads to a clear win. But what else? If 36... Kc7 (out of the d file after Rd1) 37. Bc2 Nh6 38. Kh6 d3 39. Bd3! Rd3 40. g4 c2 41. Rc1, White wins.

  Mateo: 33... Re2 (?) could be the mistake that should have given Bacrot a won game had he played the excaliburian 37. Rd1!, the Graal pointed by <LancelotduLac>.

I suggest the improvement 33... Ne3. For instance, 34. Kg7 Rh2.

  Pawn and Two: <euripides> Thank you for the information regarding computer analysis for evaluation of the Q+P vs Q endgame. One can learn something new about chess every day on this site.
Mar-01-06  vardan: To Mateo:
I think that after 37. Rd1 Rg3 38. Rd4
the black can move 38. ... Ke7 and in this situation white has to fight for a draw. F. e.
a) 39. Rc4? Ne5+
b) 39. Bg6 Ne3 40. h7 Nf5+
c) 39. Nd8 Ne5+ 40. Kh8 Ng6+ etc.
Black can also try 40. ... Nd7 or 40. ... Ke8.

1) 40... c2 41. Nc8 #.

2) 40... Nd5 41. Rd5! Rg6 (41... ed 42. Nf5) 42. Kg6 ed 43. Nf5, White wins.

3) 40... Nf5 41. Nf5 ef 42. h7, White wins.

Oct-17-06  positionalgenius: One of the best games this year.
Feb-23-07  micartouse: Another game where Aronian ends up down two pieces in the ending but wins.

Aronian vs Anand, 2007

He's not pulling these games off against lightweights either. It must be very hard to concentrate when playing such sharp positions.

  GrahamClayton: There was some interesting play from moves 16-20. Is the reason why White did not play 19. ♖a1 because of 19...♖a8, where he will end up with either R + N or R + B versus R + R?
Feb-03-13  master of defence: Maybe better for white was 17.Nxb7 Nc2+ 18.Kd2 Nxa1 19.Rxa1 Ra7 20.a4 Rb8 21.a5 Rbxb7 22.Bxb7 Rxb7 23.a6 Rc7 24.Kc3.
Aug-17-15  Imran Iskandar: This is probably one of the most epic games made GOTD this year. Amazing.
