You can follow GM Evgenij Miroshnichenko's review from the rounds 4 - 8 below;

Well, instead of the proper review with all the important results (which all of my readers can easily find on the webpage you’re reading this text from) covered for a second consecutive time I’m rather bringing you just a few fragments of the whole puzzle, although I hope you can restore the picture of how tense this tournament is, and while it may seem to one that I’m pretty much criticizing the guys (and young ladies of course) for the mistakes they make, one should note that your truly has never actually managed to qualify for U20 World Championship in his past, so it might be just a sign of my envy speaking inside of meJ. While it’s an obvious thing how important those “middlegame” rounds have been for the leading group (I hope my daily reports are enough to cover this subject at least partly), my belief is the most important in a chess review is that it actually has to be easy to read, and I hope you’ll enjoy those spectacular (and sometimes funny) moments I’d like to share.

White probably thought he's going to win d5 pawn with his next move. 16.g4 Bxg4 Brave piece sacrifice, although the alternatives were hardly sufficient: [16...Bg6 17.g5 Nh5 18.Nxd5 and White is just a pawn up.; Perhaps Black can try 16...d4!? 17.Ne4 Nxe4 18.Bxe4 Bg6 19.Nxg6 hxg6 20.Qc4!? Qe7! 21.b4 where still I believe White to be better with a pair of bishops.] 17.hxg4 Qxg4 18.Nf3 Black's compensation shouldn't be underestimated, particularly in a practical game as when your king is under attack, nothing comes that easy... 18...e4! [In case of 18...h5 White should've to find the only way to defend h3 square - 19.Kf1 h4 20.Ng1! with an advantage.] 19.dxe4 dxe4 20.Nh2?! [Dangerous for White could be a try to leave the king on his own - 20.Nd4 Rac8 21.e3 Ne5 22.Qe2 Qg6 23.Rad1 Bc5 24.Kf1 Rfe8 where Black is not in hurry to attack but just keeps positional pressure.] 20...Bxh2+ 21.Kxh2
 



21...Qf4+ This should've lead to a draw. [Black could've started with 21...e3!? where he seems to have at least a draw as well - 22.f3 (Bad is 22.Nd1 Rac8 23.Bc3 Rfe8 intending to bring one of the rooks into attack via 5th rank.; Scary as well looks 22.fxe3 Qh4+ 23.Kg1 Ng4 24.Nd5 Qf2+ 25.Kh1 Rfe8 26.Qc4 Qh4+ 27.Kg1
 



27...Rxe3! although after 28.Qxg4! Qxg4 29.Nxe3 the position is rather unclear - 29...Qg5 30.Nd5 Re8 31.Rac1 h5 32.e4 and I'm still not sure who's better) 22...Qh4+ 23.Kg1 and it seems Black has to accept a draw by perpetual, as tempting 23...Rac8 is refuted nicely with 24.Qf5! Rc5 25.Qh3 Qf2+ 26.Kh2! Rh5 27.Rf1 Rxh3+ 28.Kxh3 where Black's queen is trapped right after he captured the opponent's.] 22.Kg1! e3 23.Nd1 [In case of 23.f3? Black would have to find 23...Rac8! 24.b4 (defending c5 square, thus not letting Black to transfer the rook via the 5th rank) 24...Ne5!µ and Black slowly increases the pressure.] 23...Ng4! 24.f3 [Bad would've been 24.fxe3 Qg3 25.Bc3 Ndf6! 26.Qf5 Rac8 27.Bb4 Qh4! and Black is threatening to bring his knight to g3 via h5. 28.Qf3



28...a5! 29.Bc3 Qh2+ 30.Kf1 Rxc3 31.Nxc3 Qe5 32.Kg1 Qxc3 with advantage for Black.] 24...Qg3 25.Qc3 [After 25.Bc3 Nf2! Black seems to be fine - 26.Qf5 g6 27.Qxd7 Rad8 28.Qe7 Nh3+ 29.Kh1 (29.Kf1 Qh2 30.Qxe3 Rfe8 31.Bxh3 Qxh3+ 32.Kg1 Qg3+=)



29...Rxd1 30.Raxd1 Nf2+ with perpetual] 25...Ndf6! 26.fxg4 Rfc8



27.Qxe3 [Too dangerous would've been 27.Qb4 a5 28.Qxb7 Qxe1+ 29.Bf1 Nxg4] 27...Qxe1+ 28.Bf1 Nxg4 29.Qf4 Rc6! 30.Nf2 Qxf2+ 31.Qxf2 Nxf2 32.Kxf2 



The resulting endgame is balanced, although Black didn't manage to carry it properly and lost in the end... 32...Rb6 33.b4 a5 34.Bd4 Rd6 35.Bc5 Rf6+ 36.Ke1 axb4 37.Bxb4 h5 38.Bg2 Rb8 39.Rd1 b6 40.Rd7 Re8 41.Bc3 Rfe6 42.Bf3 Re3 43.Kd2 g6 44.Rb7 R3e6 45.Bd4



45...Ra8? [45...R8e7! would've been just enough for a draw - 46.Rxb6 Rxb6 47.Bxb6 Re6 48.Bc5 h4 49.Ke1 g5 50.Kf2 Kh7 and Black doesn't seem to be worse.] 46.Bd5! Rd6 47.e4 Now White's superbly coordinated pieces create a deadly threats against black king. 47...Rdd8 48.Rxb6?! [Perhaps after 48.Rxf7 Rxd5 49.Rg7+ Kf8 50.exd5 Ra5 51.Rxg6 Rxd5 52.Kc3 Ke8 White could be a bit worried about "the wrong bishop", but of course with the rooks being on the board it doesn't have to be hard to win.] 48...Ra4 49.Ke3 Rxa3+ 50.Kf4 Rd3 51.Bf6 [51.Be5!]



51...Rf8 [A try to transform into R+B vs R with 51...g5+ doesn't work, as after 52.Kxg5 R3xd5+ 53.exd5 Rxd5+ 54.Kh6 White will mate soon.] 52.Be7 Rc8? [After the most stubborn 52...Re8 53.Bg5 Rd1 54.Rxg6+ Kh7 55.Rh6+ Kg7 56.Rxh5 Rf1+ 57.Kg4 Re1 White still can avoid R+B vs R endgame - 58.Kf5 Rf1+ 59.Bf4 f6 60.Kg4 Re1 61.Kf3 Rf1+ 62.Kg3 Re1 63.Rh4! although his task to win would be much harder compared to the game.] 53.Rxg6+ Kh7 54.Rf6 Rcc3 55.Rxf7+ Kg6 56.Rf6+ Kg7 57.Ke5 [57.Kf5!! Rf3+ 58.Ke6 Rcd3 (58...Rxf6+ 59.Bxf6+ Kg6 60.Bxc3) 59.e5+-] 57...Rf3? [57...Rc8 could still prolong the game.] 58.Bf8+ [58.Bf8+ Kh7 59.Rh6#] 1–0

Black went for a sharp break on the queenside, which was the start of all the funny little things which happened in this game 15...b5?! Could've give white an advantage, although till the certain point this move worked just fine. 16.axb5 axb5 17.cxb5?! [More precise would've been 17.Ne7+ Kh8 18.cxb5 Nb6 19.Nc6 Nxc6 20.Rxa8 Na7 21.Rxa7 Qxa7 22.0–0±] 17...c4?! [Most stubborn 17...Nb6 18.Ng3 Bd7 19.c4 is still not so promising for Black, and after all, he didn't sacrifice a pawn to defend such a position.] 18.Bxc4 Nb6 19.Bxb6 Qxb6 20.Ne7+ Kh8



21.Qf2? [White should've continued 21.Nc6 Bd7 22.Kd2 Nxc4+ 23.Qxc4 where 23...f5 seem to give Black at least some initiative in reward for two pawns he sacrificed. 24.Rxa8 Rxa8 25.Rf1! f4! 26.Kc2 Qe3 27.Rd1 Ra3 28.Kb2 Ra8 and it's still not over yet.] 21...Qb7! 22.Nc6 Nxc6?! [Black should've preferred 22...Nxc4 23.Rxa8 Qxa8 24.Qa7 Qxa7 25.Nxa7 Bd7 26.Nc6 Ra8 with decisive advantage, as white pawns are safely blocked for the moment.] 23.Rxa8 Qxa8 24.dxc6! Qa1+ 25.Ke2 Qxh1 



26.Qf1! Qxh2 [26...Qxf1+ 27.Kxf1 g6 28.b6 Kg7 29.c7 Kf6 30.Bd5 Ba6+ 31.Ke1 Ke7 32.b7 Bxb7 33.Bxb7 Kd7 34.c8Q+ Rxc8 35.Bxc8+ Kxc8 36.Kd2 looks like a draw, but why not to keep queens being a rook up?] 27.b6 Qh4 28.b7 Bxb7 29.cxb7 Rb8 [Easier seems to be 29...Qd8 30.Bd5 Qb8 and then just moving the king on g8 and h8 as I don't see how to make any progress for White.] 30.Bd5 With such a strong passed pawn White definitely has a compensation, but it's still hard to imagine how to lose it with Black... 30...Qe7 31.Qb1 Qc7 32.Kd3 g6 33.Qb5 Kg7



34.Qc6! Qxc6 [Black should've kept the queens on the board with 34...Qa5 , as after 35.Qxd6 Qb5+ 36.Ke3 Rxb7 37.Bxb7 Qxb7 38.Qxe5+ Kg8 there's a fair chance to escape in the resulting queen's ending, although it wasn't easy to understand that an endgame in the game would be lost.] 35.Bxc6 Kf6 36.Kc4 Ke7 37.Kb5 Eventually white king reaches b6 and Black finds himself in a zugzwang as soon as he runs out of pawn moves.

37...f5 38.Kb6 Kd8 Unnecessary trick, which, while still wins a game, could've slightly complicate matters. 39.f4!? [White could've just wait with 39.Bb5 where Blacks eventually runs out of moves - 39...fxe4 40.fxe4 h5 41.Kc6 g5 42.Be2 g4 43.Bd1+-] 39...fxe4 40.fxe5? But this mistake could've coasted White a win! [40.Bxe4 exf4 41.c4 Kd7 42.Bc6+ Kd8 43.Bf3 Kd7 44.Bg4+ Kd8 45.Kc6 was just enough to take the point.]



40...e3 41.Bf3 dxe5?? Incredible mistake when Black was just a step away from salvation! [Correct was 41...d5! not giving White the passed pawn on c-file. 42.Kc6 Ke7 43.Kc7 Rf8 44.Bg4 (Bad would've been 44.b8Q Rxb8 45.Kxb8 Ke6 and White just gave to many pawns - 46.Kc7 Kxe5 47.Kc6 d4! 48.cxd4+ Kxd4 49.Kd6 Kd3 50.Ke5 e2 51.Bxe2+ Kxe2 52.Kf6 Kf2 53.g4 Kg3 54.g5 Kf4 and Black is finally winning.) ] 42.c4 Ke7 43.c5 Rf8 44.c6 [44.c6 Rxf3 45.b8Q e2 46.Qxe5+ Kf7 47.gxf3+-] 1–0

This game wasn't really important in the fight for the medals, but the position was so picturesque that I couldn't resist putting it into this review. 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5 5.dxc5 Bxc5 6.Nf3 Qb6 7.e3 Qc7



8.g4!? And interesting idea, which already has been played on a grandmaster level. 8...Nxg4 9.Rg1 Ne5?! [9...Nxh2 10.Nxh2 Qxh2 11.Rxg7 Nc6 12.Rg3 b6 (12...h5!? could be an idea to improve on Black's play) 13.a3 Bb7 14.b4 Bd6 15.Rh3 Qg1



16.Bb2 Be5 was played in Bareev,E (2675)-Gurevich,M (2635)/Elista (m/1) 1998/, where after 17.f4! Bxc3+ 18.Bxc3 Rg8 19.0–0–0 White supposed to have much better chances.] 10.Nxe5 Qxe5 11.f4 Qf6 12.Bd2 Qh4+? A start of unlucky sequence of moves, which eventually delivered quite an unusual position after 14th move. [12...Qh6 13.0–0–0 Nc6 14.Rg3 still looks much better for White though.] 13.Rg3 Bf8? 14.0–0–0 Qd8?



I've hardly seen such a bad lack of development any time before! No surprise it didn't took White too much time to finish the game. 15.Ne4 f5 16.Ng5 Nc6 17.Bc3 Qe7 18.Be2 Kd8 19.e4 h6 20.Nf3 fxe4 21.Qxe4 Qf7 22.Ne5 Nxe5 23.Bxe5 Qf5



24.Qd4 And with most of his pieces being still on their initial squares Black resigned the game. 1–0

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.f3 0–0 5.e4 



5...b6? [5...d5 is well-known and strong here.] 6.Bd3 Ne8? Those two last moves need an explanation I'm afraid. Black was (If I might guess) shown a variation with 5.a3 Bxc3 6.bxc3, where moves he's playing in the game are actually to the point, and decided to wait for White to play a2-a3 in order to transfer into familiar position.:) 7.Nge2 Nc6 8.Be3 e5 9.d5 Ne7 10.Qc2 Nd6?! This is too artificial, so no wonder Black get's into trouble. [10...Ng6 11.0–0–0 Bc5 12.Bd2 would've been still much better for White, although it would've at least keep the game "normal".] 11.a3 Bc5 12.Bd2 a5



13.Na4! After this move White gets huge advantage by force. 13...Nb7 14.b4 axb4 15.axb4 Bd4 [Relatively better would've been 15...Bd6 16.0–0 c5 17.Be3 Ra6 where White is "just" much better. ] 16.Nxd4 exd4 17.0–0 d6 18.c5 bxc5 19.bxc5 dxc5 20.Nxc5 Rxa1 21.Rxa1 c6 This allows nice tactical finish!



22.Nxb7 Bxb7 23.Qb2 Ba8 24.Bb4 cxd5 25.Qa3 [25.Qa3 Re8 26.Bxe7 Qxe7 27.Qxe7 Rxe7 28.Rxa8+ Re8 29.Rxe8#] 1–0

White king is caged in the corner, so White's next move (the last before the time-control) is a try to give some fresh air to his monarch. This interesting endgame may change my beliefs about girls and an endgame technique :). 40.h3 [In the case of not playing the text White could've have better chances to escape - 40.Bb8 h3 41.Bf1 a5 42.a4! (42.Bc7? a4 finishes the game at once) 42...Kf6 43.Bc7 Bc3 44.Bd6



44...Bb4! (After 44...c4 45.bxc4 hxg2+ 46.Bxg2 Bxa4 47.h3 gxh3 48.Bxh3 White seems to be just in time to stop the opponents pawn - 48...Bc6+ 49.Bg2 Bxg2+ 50.Kxg2 Bb4 51.c5 a4

 


52.Kf3 a3 53.Ke4! Bc3 54.c6 a2 55.c7 a1Q 56.c8Q=) 45.Kg1 Bd5! 46.Bc4 (46.gxh3 Bxb3 47.hxg4 Bxa4 and black pawns are running faster.) 46...Bxg2, with an extra pawn and still good chances to win in the end.] 40...gxh3 41.Bf1 Kg6 42.Kh2 hxg2 43.Bxg2 Bxg2 44.Kxg2

 


Black has got the "wrong bishop", so White's task is to eliminate the queenside pawns at any cost. 44...Kf5 45.Kh3 [45.Bb8!? a6! (45...a5 46.Ba7 Ke4 47.Bb6 c4 48.Bxa5 c3 49.Bxc3! is an illustration of "the wrong bishop" case.) 46.Ba7 Ke4 and white is not in time to play b4.] 45...Ke4 46.Kxh4 Kd3 47.Bb8 a6 Black keeps finding only moves all the time (although so far there wasn't any tough decisions in front of him) 48.Bd6 Kc3 49.Kg4 Kb2! 50.b4 c4 51.a4



51...c3 [Easier would've been 51...Kb3 52.b5 a5!–+] 52.Kf3 c2? [52...Kb3! 53.b5 a5–+] 53.Bf4 Kb3 54.Ke4! [54.b5! a5 55.Ke4 Bf2 56.Kd5 Kxa4 57.Kc4=] 54...Bg1?! [More problems could’ve been created with 54...Kc4 shouldering White's monarch. Still Black can't win after the correct 55.b5 a5 56.Bc1 Kc3 57.Ba3 Bf2 58.Bc1 Bg1 59.Bf4 Kb2 60.Kd5 c1Q 61.Bxc1+ Kxc1 62.Kc6 Kb2 63.b6 Kb3



64.b7! (but not 64.Kb5?? Bxb6 65.Kxb6 Kxa4–+) 64...Bh2 65.Kb5 Bc7 66.b8Q Bxb8 67.Kxa5=] 55.b5 a5



56.Kd3?? Incredible blunder! [56.Kd5! Kxa4 otherwise White is able to transpose into the line from the previous comment. 57.Kc4!=] 56...Kb2 57.Kc4 c1Q+ 58.Bxc1+ Kxc1 59.Kc3 [59.Kd5 Kb2 60.Kc6 Kb3 61.b6 Bxb6 62.Kxb6 Kxa4–+] 59...Bf2 60.Kb3 Kd2 61.Ka3 Kc3 0–1

Dragomirescu, Robin-Alexandru (2349) - Nagy, Gabor (2457) [B51]

Another example of unexpected maneuvers on the board. 1.e4 c5 2.Nf3 d6 3.Bb5+ Nc6 4.Bxc6+ bxc6 5.0–0 g6 [Main move is 5...e5 here, with a widely developed theory, although this game is shown there not for an opening survey:).] 6.d4 cxd4 7.Qxd4 e5 8.Qd3 Be7



9.c4!? An interesting novelty, at least according to my database. [Both 9.h3 ; and 9.Rd1 had been previously played once.] 9...f5 10.Nc3 Nf6 Black has made a couple of natural moves after he faced a novelty just to find out he's in trouble after White's next move. 11.c5! Using a chance to undermine Black's pawn chain. 11...d5? [Probably the best would've been 11...0–0 12.Bh6 (After 12.cxd6 Qxd6 13.Qxd6 Bxd6 Black's bishop pair should compensate for his somewhat compromised structure.) 12...fxe4 13.Nxe4 d5 14.Nxf6+ Bxf6 15.Bxf8 Qxf8 where Black has descent compensation for the exchange; bad is 11...fxe4 12.Nxe4 d5 13.Nxf6+ Bxf6 as after 14.Nxe5! White not only wins the pawn, but has complete domination over the dark squares.] 12.Nxe5 fxe4 13.Qd4 Bb7 14.f3! Opening the f-file for the rook. 14...Qc7?! [The position after 14...0–0 15.Bh6 Re8 16.fxe4 Bxc5 17.Qxc5 Rxe5 18.Rae1 looks hardly defendable for Black as he has got too many weaknesses here and there, albeit the move in the text is hardly better.] 15.fxe4 0–0–0 16.exd5 Nxd5 Black has been hoping for some tactical tricks there I suppose, but White just brutally captured everything what was on offer without giving anything away. 



17.Nf7! After this White is simply winning, but I've intentionally left the remaining moves in the text just to illustrate another unusual phenomenon - King's walk towards the 1st rank. 17...Rhf8 18.Nxd8 Rxf1+ 19.Kxf1 First step! 19...Qxd8 20.Nxd5 Qf8+ 21.Bf4 Ba6+ 22.Ke1! The second one, and once again forced, as [22.Kg1?? Bxc5 would've lost a queen.] 22...Bxc5 23.Qe5! Bb4+ 24.Kd1 and the third step, eventually getting read of those annoying checks. :) 24...Ba5 25.Qb8+ 1–0
