That was not the case the second time.<\/p>\n<p>On the weekend after New Year&#8217;s Day in 1988, I decided to play in one of Bill Goichberg&#8217;s big tournaments, the Continental Open, to start the year. I was living in North Carolina at the time and the tournament was in Rye, New York, so it was a pretty long trip. But I was on the cusp of making my first National Master rating (2200), and I had just won my second state championship. I was feeling very confident in my chess and thought that I had a good shot at a prize in the Under-2200 section.<\/p>\n<p>In fact I tied for second, with a 4\u00bd-1\u00bd score, and I did reach my goal of 2200. So it was a great tournament for me.<\/p>\n<p>The one person who finished ahead of me, at 5\u00bd-\u00bd, was an UNRATED player named Gustavo Hernandez. Right away, when you are playing at a Bill Goichberg tournament and you see an unrated player from a foreign country winning game after game in the under-2200 section, you think, &#8220;Ringer.&#8221; It&#8217;s a problem Goichberg has faced throughout the years, because he organizes the biggest money tournaments in the U.S., and they are a magnet for sandbaggers and foreign players with no USCF rating. Goichberg does his best to figure out the true strength of these people, but he doesn&#8217;t always succeed.<\/p>\n<p>So going into this game, I knew I was facing a strong player but I didn&#8217;t know how strong. I heard after the tournament that he was the champion of the Dominican Republic. But nobody told me &#8212; probably nobody knew &#8212; that he was in fact the world under-18 champion! I didn&#8217;t find out until 23 years later &#8212; last year, in fact &#8212; when I just happened to read the Wikipedia article on the <a href=\"http:\/\/en.wikipedia.org\/wiki\/World_Youth_Chess_Championship\" target=\"_blank\">World Youth Chess Championship<\/a>. At the very top of the list of winners of the under-18 title, the winner of the first tournament in 1987, was &#8230; Gustavo Hernandez of the Dominican Republic!<\/p>\n<p>In future years, the winners of this title would include a virtual Hall of Fame of chess talent: Vladimir Kramnik, Shakhriyar Mamedyarov, Ruslan Ponomariov, &#8230; I&#8217;m still very proud of earning a draw against a player on such a list. (Hernandez, by the way, is still active in FIDE chess and is an International Master.)<\/p>\n<p>The opening and middlegame of this game are not too interesting, but the endgame is very interesting indeed. Hernandez felt after the game that he must have missed a win somewhere. I didn&#8217;t think so. I was especially proud of my move 35. &#8230; b4, a pawn sac that allowed me to activate my rook.<\/p>\n<p>Twenty-four years later, Rybka reveals the truth &#8230; but you don&#8217;t want me to give it away so easily, do you? For readers who want an analytical challenge, play through the game in the PGN viewer below. I have deliberately not made any comments after move 23. You have two questions to answer:<\/p>\n<ol>\n<li>Was Hernandez right?

Kxe4 (analysis). Black to move.<\/p><\/div>\n<p>FEN: 8\/1p6\/p1ppk3\/7p\/3PK3\/7P\/PPP5\/8 b &#8211; &#8211; 0 30<\/p>\n<p>Win for White or draw? This one is right on the borderline. The idea for Black is to play 30. &#8230; Kf6 31. Kf4 a5! Note that Black can never win the battle for the opposition, because White has a free move (h4) and Black doesn&#8217;t (&#8230; h4 loses a pawn). Nevertheless, White cannot break through unless he dislodges the pawn at d6. In order to do this, White has to play for the break\u00a0 c4-c5. Black&#8217;s defense is to play &#8230; a5 and &#8230; b6 and exchange as many pawns as possible. Rybka says that this idea is just good enough to draw, although Black has to find a couple of only moves. I&#8217;ll leave it to you (or your computer) to figure out the remaining details.<\/p>\n<p>Hernandez&#8217;s 25. Rd3 showed great judgement. He obviously couldn&#8217;t work the K+P endgame out to a clear win, and there&#8217;s an old saying that you don&#8217;t want to enter a K+P endgame unless you&#8217;re absolutely sure it wins. The point of 25. Rd3! is that White would like to enter <em>the same K+P endgame\u00a0 a tempo ahead<\/em>, after 25. &#8230; Kd7 26. Rg3 Rxg3 27. Kxg3. Now he would be completely winning!<\/p>\n<p>Of course Black doesn&#8217;t have to allow this. The simplest solution, as Rybka points out, is just to play 25. &#8230; Rg7 with the idea of answering 26. Rg3 with 26. &#8230; Re7 pressuring the e5 pawn. I can&#8217;t argue with that. So technically, Rybka is right. White&#8217;s subtlety with 25. Rd3 made no difference if Black defended perfectly.<\/p>\n<p>However, humans aren&#8217;t perfect! I was afraid of 26. Rg3 and played <strong>26. &#8230; h4?!<\/strong> This isn&#8217;t the losing move but it is an inaccuracy, because the pawn on h4 is an easier target than it was before.<\/p>\n<p>Now let me get to those questions I started out with. I&#8217;ll answer the second one first.<\/p>\n<div id=\"attachment_1431\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-4.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1431\" class=\"size-medium wp-image-1431\" title=\"hernandez 4\" src=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-4-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-4-300x300.jpg 300w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-4-150x150.jpg 150w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-4.jpg 498w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-1431\" class=\"wp-caption-text\">Position after 34. c3.

His move <strong>34. c3!<\/strong> has created a zugzwang, where Black has to retreat with either his rook or his king. I played <strong>34. &#8230; Rh7<\/strong> and Hernandez played <strong>35. Rg8<\/strong>. And now I played the surprising <strong>35. &#8230; b4<\/strong>, with the idea that after 36. cb? Rb7, essentially all five of White&#8217;s pawns are islands. None of them can defend the others.<\/p>\n<p>However, Hernandez continued to play perfectly for several more moves and achieved a winning position. So we have to conclude that 35. &#8230; b4 was a blunder, even though it looked great at the time. Rybka says that Black must first safeguard the d-pawn with 35. &#8230; Rd7! and only after a move like 36. Rh8 play 36. &#8230; b4! If White tries to stop &#8230; b4 altogether with 36. Rb8, Black seizes the g-file with 36. &#8230; Rg7! and sinks the rook into g3, with enough counterplay to save the game.<\/p>\n<p>In other words, I had the right idea but the wrong execution. Chess is pretty darned subtle sometimes. When you see a great shot like &#8230; b4 it&#8217;s very hard to hold back from playing it.<\/p>\n<p>Hernandez capitalized on my error in exactly the right way, according to Rybka: after <strong>35. &#8230; b4?<\/strong> he played <strong>36. Rd8!<\/strong> (hitting the d-pawn) <strong>bc 37. bc Ke6 38. Kg4 Rc7 39. Ra8 Rxc3 40. Rxa6+ Ke7 41. Ra7+ Ke6 42. Ra6+<\/strong> (obviously played to gain time on the clock) <strong>42. &#8230; Ke7<\/strong> and now we reach the position where White makes his only blunder of the game.<\/p>\n<div id=\"attachment_1432\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-6.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1432\" class=\"size-medium wp-image-1432\" title=\"hernandez 6\" src=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-6-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-6-300x300.jpg 300w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-6-150x150.jpg 150w, https:\/\/danamackenzie.com\/blog\/wp-content\/uploads\/2012\/04\/hernandez-6.jpg 498w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-1432\" class=\"wp-caption-text\">Position after 42. ... Ke7. White to move.<\/p><\/div>\n<p>FEN: 8\/4k3\/R4p2\/P2p4\/3P2Kp\/2r4P\/8\/8 w &#8211; &#8211; 0 43<\/p>\n<p>I&#8217;ve said before that one reason chess is so much harder than it appears to be in books is that when you&#8217;re playing a game, you never have someone to tap you on the shoulder and say, &#8220;White to play and win.&#8221; That gives you two big clues: First, White should be looking for a win. (Well, that is obvious here, but sometimes it isn&#8217;t.) Second, the fact that it&#8217;s a puzzle in a book means the obvious move probably isn&#8217;t the right move.<\/p>\n<p>In the game Hernandez played what seemed like a completely natural move: <strong>43. Kxh4?<\/strong> I doubt that he even took very long thinking about it. This is exactly where he needed someone to tap him on the shoulder and say, &#8220;Think about it.&#8221;<\/p>\n<p>What&#8217;s wrong with 43. Kxh4? The answer is that it gives Black enough time to win the d-pawn. With 43. Ra8! the a-pawn gets moving one tempo quicker and Black<em> does not have time<\/em> both to win the d-pawn and to get his king to the &#8220;safe haven&#8221; of g7 and h7. After 43. &#8230; Rd3 44. a6 Rxd4+ 45. Kf5 Ra4 46. a7 Kf7 and White wins with the oldest trick in the book: the X-ray check 47. Rh8! Rxa7 48. Rh7+. Black was one tempo short of a draw.<\/p>\n<p>But after the tempo-losing <strong>43. Kxh4?<\/strong> Black does have time both to corral the d-pawn and to stop the a-pawn. The game concluded <strong>43. &#8230; Rd3 44. Rb6<\/strong> (some kibitzers criticized this after the game, but there was nothing better) <strong>Rxd4+ 45. Kh5 Ra4 46. a6 d4 47. Kg4 d3+<\/strong> (my second discovered check with a pawn in one game!) <strong>48. Kf3 Rd4! 49. a7 d2 50. Rb1 Ra4 51. Rb7+ Ke6 52. Ke2 Ra2 53. h4 f5<\/strong> \u00bd-\u00bd. With the threat of &#8230; f4-f3+ looming, White has to give up his a-pawn to win the d-pawn, and the game is then a complete draw.<\/p>\n<p>I think that the position on White&#8217;s 43rd move is a beautiful case study to illustrate the fact that TEMPI are more important than MATERIAL in rook endgames. It&#8217;s ironic that White&#8217;s excellent 25th move showed his awareness of the value of a tempo, but he forgot to be aware of it later.<\/p>\n<p>Also, this game shows that you can&#8217;t see what you don&#8217;t look for. An IM-level player should be able to spot the winning idea with Ra8 and the X-ray check &#8212; it&#8217;s a familiar pattern that is in every endgame book. I think that Hernandez just took the h-pawn automatically and forgot to look for something better.<\/p>\n<p>Hope you enjoyed this game!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When I played my first game against a world champion (the world computer champion, Belle, in 1983), I knew that I was playing a world champion.
