Logjam Atop Leaderboard at U.S. Junior ClosedBy Brian JerauldSAINT LOUIS (June 19, 2013) -- Still, no one can find distance in the standings at the 2013 U.S. Junior Closed Championship.Today marks the players? rest day after Tuesday?s round 5 pushed the nine-game round-robin tournament past its halfway point. But despite a finish line that now looms, seven of ten players still sit within a point of each other, now with three tied atop the standings at 3.5/5 points.California IM Daniel Naroditsky, the field?s highest-rated player, was the sole leader entering Tuesday and has yet to lose a game this week at the Chess Club and Scholastic Center of Saint Louis. But his fifth-round draw against FM Sam Sevian slowed the pace, and wins from both FM Luke Harmon-Vellotti and FM Robert Perez brought them both up to speed. Harmon-Vellotti?s come-from-behind shocker over IM Victor Shen made it two wins and a draw against the field?s three top-seeded IMs; and Perez has shrugged off a slow start to the tournament to notch three straight victories, including Tuesday?s turnaround matchup versus FM Yian Liou.After an outstanding opening that found Shen up two pawns, including one passed on the sixth rank, he did everything he could to let his solid position slip away against Harmon-Vellotti ? and he eventually got his wish. The game transposed to a Queen?s Indian, with Shen grabbing a solid foothold in the center and prepping his bishops for dominance. But Harmon-Vellotti?s 12. ? Qf6 was very suspicious, begging for Shen?s 13. Bc3 response. The move showed Shen?s position clearly winning, with an advantage in development, a better dominance of space and several tactical opportunities brewing. He quickly converted it to a material advantage.But after wrecking the black queenside, Shen found trouble re-coordinating his pieces and was never able to find traction behind his three passed pawns, including two connected. Meanwhile, Harmon-Vellotti slowly pieced together a harmonious defense and let Shen sink into time pressure.?That was going into a winning endgame [for Shen], so I just tried to make it as complicated as possible,? Harmon-Vellotti said. ?And then he blundered in time trouble.?Indeed, with under five minutes on his clock and eight more moves until time control, Shen offered up 32. Rxb5 with tactical eyes. But Harmon-Vellotti defied the play with 32. ? Rbxb6, ultimately releasing nearly all of white?s pressure and gathering the d6 passer. Even still with winning chances, Shen struggled to find any continuance, and Harmon-Vellotti wreaked havoc on the white king with his remaining knight and rook. The move 57. ? h5 kicked off a race to queen ? one that Shen actually won, but left him positionally inferior.?[Shen] was winning all the way down to [53.]Kg1,? Harmon-Vellotti said. ?I think if he had gone Ke1, he would have won.?Perez performed his own climb out of a dark position thanks to an outstanding endgame and some fantastic work with his king. The game progressed through an unusual line of the Sicilian, but one Liou was up to the task of pressing. For more than 20 moves, he kept Perez on the defensive and looked primed to push solid queenside space into an advantage.But his 23. Ncd5 ignited a massive swap-out of material, ultimately leaving Perez with a bad bishop and Liou in control of the outpost ? though limited in attacking ideas. ?He was still better, but compared to what the position was before, I was able to get rid of a lot of pieces and centralize my king,? Perez said. ?Yeah, my d6 was weak, but bad bishops defend good pawns.?That d6 pawn was more than ?good? ? it was the winner ? as it was able to work its way over to the e-file and eventually down to its queening square. And it would not have been possible without the major play of Perez?s king, who helped open up some lanes against Liou?s kingside pawns and then escorted his passer to safety.After 37. Rdxe5 dxe5 38. Bxf8 won white a pivotal pawn advantage, 42. c5 allowed
