In round 1 I lost (well, sacrificed) a pawn and managed to draw. In round 2, as I showed in my last entry, I was down an exchange for a pawn and still managed to win. Round 3 was my only relatively simple game, a 35-move victory.<\/p>\n<p>But then things got seriously crazy. In round four I played a never-to-be repeated gambit that I actually analyzed about 10 years ago and thought was okay for me. But it wasn&#8217;t. My position spiraled downhill to the point where I was three pawns down (on the board) &#8212; but even worse than that, in Rybka&#8217;s analysis I was TEN pawns behind! Nevertheless, I managed to save a draw. It&#8217;s hard to remember a single game, at least since I was a beginner, where I was more busted and yet saved the game.<\/p>\n<p>I was not intending to show the game in this post, because I didn&#8217;t want to embarrass my opponent.

Bg2. Black to move.<\/p><\/div>\n<p>This position marks the absolute nadir of my game, according to Rybka. It&#8217;s easy to see why. Not only am I down three pawns, I am also effectively down a rook, because neither my rook on a1 nor my king on b1 can ever move. Rybka evalutes the position at +10.04 pawns for Black, mostly because after 33. &#8230; a2+ it sees a forced mate or win of a ton of material. (I think the point is 34. Kb2 Nb6.) However, this takes a little bit of calculation. The move that my opponent played, <strong>33. &#8230; g5<\/strong>, should have been good enough. But things started going a little bit haywire for him after <strong>34. cd Bxd5?<\/strong> Why did he take this way? Simply 34. &#8230; ed should be killing. Black doesn&#8217;t mind opening the e-file because he can play &#8230; Re8 and trade rooks, and then (as noted before) he is essentially a rook up.<\/p>\n<p>Well, I don&#8217;t want to do a lot of analysis because there are a million and one ways that Black should have won this game. After <strong>35. Nxd5 Nxd5 36. gf!<\/strong> all of a sudden his center is collapsing. He played <strong>36. &#8230; Nc3+<\/strong> (which is also Rybka&#8217;s top choice) <strong>37. Kc1 ef 38. Bxa8 b2+ 39. Kc2 baQ 40. Rxa1 Rxa8 41. Kxc3<\/strong>, leading to the second diagram position.<\/p>\n<div id=\"attachment_2450\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-2.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2450\" class=\"size-medium wp-image-2450\" title=\"mackenzie rand 2\" src=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-2-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-2-300x300.jpg 300w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-2-150x150.jpg 150w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-2.jpg 498w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-2450\" class=\"wp-caption-text\">Position after 41. Kxc3. Black to move.<\/p><\/div>\n<p>It&#8217;s amazing how much progress White has made, yet I am still totally busted. Previously I was down 3 pawns (really) and 10 pawns (according to Rybka). Now I&#8217;m down 2 pawns (really) and 4 pawns (according to Rybka). And yet there really should be no hope here for White.<\/p>\n<p>But a funny thing happened. I just kept playing and playing, constantly expecting almost every move to be put out of my misery, and yet it never happened. There was always another resource. I would have resigned if he had given me a good excuse to, but he never did. We finally got to a position with R+N+2P versus R+N that still should have been a win, but it got harder and harder, and finally I was able to trade rooks and get to a drawn endgame of N+P versus N.<\/p>\n<p>The only problem was that I was almost out of time! By move 68, when the above scoresheet ends, I was down to less than a minute. So even though the position should be a dead draw, it was not at all clear that I was going to succeed in drawing before my time ran out even with a 5-second time delay on the clock). But finally, with 14 seconds left on my clock, we got to the position shown here.<\/p>\n<div id=\"attachment_2451\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-3.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2451\" class=\"size-medium wp-image-2451\" title=\"mackenzie rand 3\" src=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-3-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-3-300x300.jpg 300w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-3-150x150.jpg 150w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2013\/09\/mackenzie-rand-3.jpg 498w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-2451\" class=\"wp-caption-text\">Position after move ??. White to move.<\/p><\/div>\n<p>Here I played <strong>1. Ne4!<\/strong> and at last the draw is completely clear. If Black plays <strong>1. &#8230; Ne5<\/strong> I will play<strong> 2. Nf2<\/strong> and sacrifice my knight for the pawn. Instead he played<strong> 1. &#8230; Nf4<\/strong>, and with 12 seconds left on the clock I played<strong> 2. Nd6+ Kg5 3. Ne4+ Kh5 4. Nf6+ Kg5 5. Nxg4<\/strong>, draw.<\/p>\n<p>Amazingly, a very similar situation occurred in round 5, where I was Black against Igor Traub. Again I got a very difficult endgame a pawn down, and again I somehow managed to wriggle out of it. My opponent couldn&#8217;t believe it, because he had thought all possible king-and-pawn endgames were won for him, but I was able to set up a fortress. He agreed to a draw when I had 28 seconds left.<\/p>\n<p>In both of these games, as well as round 2, my game was the very last one to finish, and each time the TD, Richard Koepcke, was watching like a hawk in case he would be called upon to make a ruling on a draw claim or a flag fall. I joked that this was starting to become a habit!<\/p>\n<p>Round 6 was fairly sedate by comparison. Against Eric Steger I got a position that seemed a little bit superior, but I wasn&#8217;t able to find a win and we agreed to a draw around move 45. This time my game was one of the last to finish, but not the very last, and I told Richard, &#8220;I finished early this time!&#8221;<\/p>\n<p>So my final record was 4-2, with 2 wins, 4 draws, and no losses (but a lot of heart-stopping moments). All in all I feel pretty good about my result. I think I tied for fourth in the expert section and will receive a small cash prize. It would have been nice to do better today (rounds 5 and 6), but it&#8217;s tough to compete for first when you have Black in both of the last two\u00a0 games.<\/p>\n<p>Now here&#8217;s where I should report on the rest of the results of the tournament &#8212; who won the master section, the expert section, etc. But I have to apologize. After my game with Steger I was too eager to get home, and I completely forgot to look at the other results. But Bay Area Chess usually posts their results quite promptly, within a day or two of the end of the tournament, and I will do a short update when they do.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The 2013 CalChess State Championship had one recurring theme for me &#8212; amazing escapes.
