Botched Endgame

Round 1

5.d4  Not the most challenging line, but I had an idea.

7.Nc3  My head is not in the game yet.  My idea was to play the line I had played against Daniel.  7.a3, with 8.Bd3, even thought about it, but somehow played this instead.

8…Qa5?  I had never seen this move before, and thought it bad, but could not come up with a refutation.

9.NxNd5  In my mind, I suffered a hallucination here, thinking that if Black took with the queen, that I would win the Bb4, as if my queen were forming a battery from e1.  Anyway, I looked at 9.Rc1, and should have played it, also 9.a3 is good, but I even miscalculated this OTB and saw how it worked almost as soon as I noticed the computer’s eval on it.  Just wasn’t firing on all cylinders yet.

10.a3  Again, plugging this in, it makes sense that 10.BxB is a better move, as it decentralizes his knight.

12.b4  I knew this was bad almost as soon as I played it, still too afraid to make 12.Rc1 work, which it does easily 12…Na5, 13.Qe3.

24…Rfd8?  The mistake I had been hoping for.

25.Nc4?  I needed to take on c8 first, to ensure that a rook would be on that square as a target.

25…a6?  He misses, as did I, the creepy looking but effective …d6!  Taking away this future outpost from my knight.

29.Rc8  I figured there had to be a stronger move than playing this right away, and 29.a4 and 29.Kf2 are equally good.

31.Nxb6?  I strongly considered 31.Be2, but didn’t realize that this was so necessary.  Gifting him the d4 pawn was drawing (I thought he might even take the h2 pawn instead).

33…Nc2?? I was hoping for this blunder, as I could see that 33…Kf7 looked equal, and is.

38.Ke3??  Paul had spent so much time on his last move, that instead of playing the winning 38.Bb7, I decided to be sneaky and played this blunder instead.  As soon as he had moved, this was the last thought that I had had in my head, so that I played it immediately, not even blunder-checking the same obvious reply 38…Nd5+, such that I played 39.a5, and he said “You’re in check”.  I didn’t know if I could still win it after this, but I knew instantly that I had blown the win, if there was one there, and let out a sigh.

I’ve examined quite a few lines with Stockfish, and there are tricky forks that obviate many a strategy.  The most direct line for a win is 38.Bb7 (dare I say the only winning move, this is what I found out by going deep into the other lines, anyway) Nd5 (here I had noticed, OTB, that taking the knight would be a draw), and here simply 39.a5 Kd6, and now for some reason it’s tempting to play 40.a6?, but 40.b6! is the win, forming a cage against his king.  It’s always important to remember that, outside of a forced pawn-race, the king and then other piece(s) become the major targets, such that one should aim to lock the opponent’s pieces out of play, unless it’s still necessary to snipe pawns.

Continuing the line above, 40.b6 Nxb6, 41.axN Kc5, 42.Bxe4 Kxb6, and now the seemingly natural 43.Bxh7?? would still draw, as the Black king can get back to h8 in time.  Correct is 43.Kf3, Kg3 or Ke3 because the important thing is not the pawns, but to block out the Black king!

Time-pressure makes fools of us all, and leaves us to guesswork.  This was my biggest mistake of the game, I was playing under 2 minutes while my opponent had an hour and 2 minutes, and these were the times basically at the very end of the game!

  1. Yeah, 25… d6 was good.
    Yes. 33… Nc2 looks like a serious blunder, missing the fork.
    Instead of 38. Ke3 computer recommends 38. a5, then 39. Bb7.
    52… e5 and 53. Kf3 were mistakes, you could play 53. Kf5 with advantage.

  2. You are right, with your comments, of course. I was so low on time the last 20-30 moves, that I was having trouble moving while keeping score correctly. I don’t think the end of the game is accurate, so I might try to fix it, but it’s sort of a lost cause. I don’t think he ever gave me that chance to play Kf5.

    It’s a pity I didn’t just win this game, let nerves get the better of me, I like your a5 idea as well as Bb7, just blundered there.
