In round 1 Daswani missed a clear win against Vicente Lee and later drew.  All other games were drawn.

In round 2 Jiang took advantage of a stubborn Yip who missed 48.Rxg7!+-, and then cleverly turned a draw into a loss by allowing a queen trade in a Q v Q+ RP ending.  Ingram upset Lee (2340-ish) with some nice endgame play causing Lee to withdraw.  Chan beat Daswani with Black in a complicated game against the 1.g3 system.

In round 3 Louie hung a piece which his opponent missed declined in time trouble and went on to lose.  Jiang eventually won the ending with three extra pawns.  Yip missed a clear win against Daswani on move 17 by offering a draw!  The position was sharp and completely symmetrical.  During a long think, Yip could not come up with the winning move and even in the postgame analysis, both players did not see the winning idea which Fritz shows almost instantly.

In round 4 Jiang crushed Chan's French defence with a nice piece sacrifice while Yip stubbornly defended a pawn down lost position against Ingram to hold a draw.  Yip played the Sicilian for a win with Black but Ingram countered with a sideline to throw Yip off.  Ingram won a clear pawn in a QRB v QRB middlegame with opposite-coloured bishops but White having Black completely tied down and passive.  The outlook was bleak for Yip but the defence was stubborn.  Yip sacrificed a second pawn to get some counterplay and continued to present problems to Ingram to solve.  Ingram missed several promising continuations, allowing Yip to secure counterplay and eventually erect a fortress for equality.  Ingram was resourceful in playing for the win, sacrificing an exchange (50.Rxg5!?) for a pawn and winning chances after Yip had erected a fortress, and even missed a clear win (65.Bf5!) after Yip defended wrongly in a sharp R+P v B+3 pawn ending.

Throughout this game, both players make massive calculation errors and constantly missed moves that would have changed the result of the game. 1.e4 c5 2.Nc3 Nc6 3.Nf3 d6 A bit casual. 3...e5 4.Bc4 Be7 5.d3 d6 (5...Nf6 6.Ng5 0-0 7.f4 exf4 8.Bxf4 d6 9.0-0 h6 10.Nf3 Be6 11.Nd5 Bxd5 12.Bxd5 Nxd5 13.exd5 Ne5 14.Qd2+= [NCO]) 6.0-0 Nf6 7.Ng5 0-0 8.f4 exf4 9.Bxf4 h6 10.Nf3 Be6 11.Nd5 Bxd5 12.Bxd5 Nxd5 13.exd5 Ne5 14.Nxe5 dxe5 15.Bxe5 Qxd5 16.Bc3 Rae8 17.Qg4 g6 18.Rae1 Bg5= 4.Bb5?!

I rejected this move in favour of a simpler plan.  6.0-0 Bg7 7.Nd5 a6 8.Ba4 h6 9.Be3 Nge7 10.Qd2 Nxd5 11.exd5 b5 12.Bb3 Ne7= 6.h3!?

Black should be fighting more actively for d5 by stopping Bg5. 8.Nd5 Be6. 8.Bc4 White likely would have retreated anyways so there was no need to spend a tempo yet. 8...b5 9.Bb3 0-0 Superficially played.  Better is 9...h6: a review of games shows this to be a key idea. 10.Nd5 Be6 11.c3=] 10.Bg5!? Be6 11.Bxf6 Bxf6 12.Nd5= Nd4 (1.20) Insufficiently thought out.  Black sees no danger after looking only one move ahead. 13.Nxd4 cxd4 14.a4 Here I suspected no danger. 14...Bg5?? (1.18) Showing an inability to calculate far enough.  Better is 14...bxa4 15.Rxa4 Bg5 16.Bc4 a5=; I rejected this line because creating an isolated a-pawn seemed like a bad idea. 15.axb5 axb5 16.Rxa8 Qxa8 17.Nc7 I missed this. 17...Qc8 18.Nxe6 fxe6 19.Qg4! I missed this. 19...Qd8 20.Qxe6+ Black has managed to miss a five-move sequence of checks-attacks-captures. 20...Kh8 21.Ra1 Qb6 22.Qd5 g6!? 23.Ra8 Bd8!? 24.f4 exf4 25.e5 Qc5! Forces White to make a big decision. 25...Kg7 26.exd6? looks hopeless. 26.exd6 Qxd5 27.Bxd5 Kg7! Black is willing to part with another pawn to activate his king. 28.Ra7+ Kf6 29.Rxh7?! 29.Bc6!? Ke6 30.d7 b4 31.Kf2? 29...Ke5! 30.Bc6 Kxd6 31.Bxb5 Bf6 32.Ba6?!+= (1.00) White starts to go astray.  32.Rb7?, this position is still quite disgusting to defend. 32...Ra8 With counterplay; for the price of another pawn, finally Black can show some activity of his own. 33.Rf7 Ke5 34.Bb7 Ra1+?! [ Better is 34...Ra2 with counterplay, I was fixated on the check and thought I was winning a pawn back.  However, this move had not occured to me 35.Kf2 Rc1? Again I missed a simple way to hold (35...Ra2.) 36.Rc7 Overlooked. 36...Rb1 37.Be4!? g5! Killing the h4 break.  Now Black can feel comfortable after a long passive defence. 38.Kf3 Rxb2+= Some tough defence and poor decisions by my opponent have enabled me to minimize the damage and now black should expect to hold. 39.Rc5+ Kd6 40.Rc6+ Ke5 41.Kg4!? Correctly activating the king. 41...Rb8?! Black misses a critical five-move sequence to hold easily: 41...Be7 42.Bf5 Kd5 43.Rc7 Bf6 44.Be4+ Ke5 45.Rc5+ Ke6+= and White can make no more progress. 42.Bf5?!+= White misses the key idea. 42.Bd5!? Re8 43.Bf7 Re7 44.Bb3 Re8 45.c3! dxc3 46.d4++- 42...Re8 43.Bg6? Better is 43.c4 - both players miss this easy win. 43...dxc3 44.d4+!+- 43...Re7?! 43...Re6= This easy one ply falls outside of Black's horizon. 44.Be4 Re8 45.c4 Too late to decide the game but now it is the only try left. 45...dxc3 46.Rxc3 Rd8 47.Rc5+ Kd4 Active and a bit risky.  However, I had no wish for more passive defence.  47...Ke6+= is safer. 48.Rf5 Rd6 48...Be7 49.Ra5? Better is 49.Rxf6! Rxf6 50.Kxg5 Rf8 51.h4 Ke3 52.h5 Rg8+ 53.Bg6+-, and Black is helpless. 49...Ke3 Trying to be consistent.  Black frees d4 to be guarded by the bishop.

 50.Rxg5!? I considered this briefly but did not take it seriously. 50...Bxg5 51.Kxg5 Now White has good practical chances to play for a win while taking no real risk. 51...Rd8!= Black must play exactly to hold. 52.h4 Rg8+ (1.19) 53.Bg6 Kd4?+- After bailing on the ..Kf2 calculation, Black deems it too dangerous and retreats.  53...Kf2! Black needs to calculate far to find a path to equality. 54.h5 Kg3 55.h6 Kxg2 56.h7 Rf8 57.Be4+ Kg3 58.Kg6 f3 59.Kg7 Rc8= Black needs to see seven moves to secure equality; this was unfortunately beyond his grasp in the game. 54.h5 Ke5 55.d4+!? The pawn is sacrificed to slow Black down.  This intermediate check was missed. 55...Kxd4 56.Kxf4 Now Black is busted.  56...Kc5 I touched the king intending ..Kd5?? but noticed the problem.  56...Kd5?? 57.Bf7++- 57.Kg5 Kd6 58.Kf6 Rf8+ 59.Kg7 Rf2 Too late. 60.g4 Rg2 61.Bf5 Ke5 62.h6 Ra2 63.Bg6 Kf4 64.h7 Ra8 65.Bf7?= Zeitnot.  65.Bf5+- Kg5 66.h8Q+- is the last chance to win the game. 65...Kg5= Hemming in the White king for a series of checks. 65...Kxg4 66.Bg8 Ra7+ 67.Bf7 (67.Kg6 Rxh7= I missed this simple move in my calculations) 67...Ra8= also draws.] 66.Bg8 Ra7+ 67.Bf7 (3) Too bad for White, he missed at least four wins in the ending. 67...Ra8= (1.10) Throughout the game, even with a massive time advantage, Black was unable to cope with the required calcuation needs of this complex ending. ½-½

One of the most interesting games of this year's Keres Memorial was the first-round encounter between Hanniegn Pitre and Bobby Meng.  Although he was significantly outrated, Pitre chose this moment to unleash a powerful attacking display straight out of the nineteenth century.  Return with us now to those thrilling days of yesteryear, when the King's Gambit was the scourge of defenders everywhere! 1.e4 e5 2.f4 exf4 3.Nf3 g5 This, the sharpest defence at Black's disposal, is a critical test of the King's Gambit.  If Black can keep the f-file closed or force White to spend a lot of time regaining the pawn, he will have good chances of equalising and can even think of gaining the advantage. 4.h4 g4 5.Ne5 This is known as the Kieseritzky Gambit.  The alternative 5.Ng5 A) As a young player, I wondered why Black did not play 5...f6 here.  Why allow White to capture on f7?  Isn't it better to keep an extra pawn?  Well, it's not that simple. White has a very strong reply in 6.Qxg4! fxg5 (otherwise White simply retreats the knight) 7.Qh5+ Ke7 8.Qxg5+ Nf6 (If 8...Ke8 then 9.Qe5+ picks up the rook.) 9.e5 recovering the piece.  Black can toss in the towel then.; B) 5...h6 leads to the Allgaier Gambit. 6.Nxf7!? The idea behind the Allgaier Gambit.  White sacrifices a piece in order to expose Black's king to attack. 6...Kxf7 7.Bc4+ d5!? Black returns a pawn in order to open lines for his pieces. 8.Bxd5+ Kg7 According to the books, White does not have enough compensation for the piece, but the position must still be played out... 5...h5 This defensive method is known (somewhat mysteriously) as "The Long Whip." [Apparently this is a translation of the corresponding German name Lange Peitsche, but I don't know the origin of the latter - ed.]  It is a reasonable one in that Black protects both his g-pawn and his pawn on f7.  The warning lights should come on when your first developed piece is a rook, and in fact the line does not enjoy a good reputation.  Nevertheless, I am firmly convinced that this was deliberate provocation by Bobby Meng.  I have seen him apply with success the strategy of sacrificing his opponent's pieces, defending, and then winning in the ending.  His bad luck here is that his opponent appears to have a good understanding of this specific opening variation. 6.Bc4 Rh7 The alternative 6...Nh6 has the drawback of forcing White to find the correct idea 7.d4 d6 8.Nd3! avoiding the sacrifice of what would be a whole piece on f7. 7.d4 d6 8.Bxf7+!? As I hinted in the previous note, White does not have to make this sacrifice.  He can retreat his knight with 8.Nd3 and play to recover the pawn on f4.  This has a certain logic because, compared with the main lines of the Kieseritzky Gambit, Black has played the rather odd moves 5...h5 and 6...Rh7 instead of developing his minor pieces. On the other hand, White's own h-pawn is now an immobile target, something Black can exploit with 8...f3 9.gxf3 Be7 This position is known from 19th-century games. White should continue with 10.Be3 Bxh4+ 11.Kd2  Although his king can no longer castle, his strong pawn centre is huge compensation and the general consensus is that White has some advantage here. 8...Rxf7 9.Nxf7 Kxf7 10.Bxf4 Bh6 11.0-0 This has all been played before, in a match game between Adolf Anderssen and Lionel Kieseritzky in 1851.  Black's next move is new -- at least to master chess. 11...Kg7 12.g3 The benefits of White's sacrifice are now clear. He has weakened Black's kingside defences and now plans to double rooks on the f-file.  Unless Black can bring his queenside pieces into play quickly, he will have a tough time trying to meet White's threats. 12...Nc6 13.Nc3 Nce7 14.Qd2 Ng6 15.Nd5 A matter of taste perhaps, but I think I would have preferred 15.Bxh6+ After 15...Nxh6 16.Nd5 Ng8 (White was threatening Nf6xh5+) 17.Nf4 Nxf4 18.Rxf4 White appears to get a favourable version of what happened in the game but without allowing any counterplay. 15...Nxf4 16.Nxf4 Qe8 16...Nf6 was a more economical defence of the h-pawn.  The only problem is that the knight is vulnerable to attack from White's rooks, not to mention his e-pawn. 17.Rae1 Ne7 18.Qc3 White rejects the unusual double attack 18.Qa5!?, probably due to the line 18...Bxf4 19.Rxf4 Ng6 20.Qxc7+ Qd7 21.Qxd7+ Bxd7 22.Rf2 Re8 and Black's pieces have come into play at the cost of a mere pawn. 18...Bxf4 19.Rxf4 Ng6 20.d5+ White could transpose to the previous note with 20.Qxc7+ but the move played in the game is stronger. 20...Ne5 At first I thought this was a mistake, since it releases the attack on White's rook and self-pins Black's knight.  But after the main alternative 20...Kg8!? 21.Rf6 Ne5 22.Qxc7 the complications favour White, for example, 22...Nf3+ 23.Kf2 a5!? (if 23...Qd7 24.Qxd6! Qxd6 25.Rxd6 Nxe1 26.Kxe1 and Black is helpless against White's armada of pawns; while after 23...Nxe1 24.Qxd6 is immediately decisive) 24.Rxd6 Bf5 25.Re2 Qe5 26.Rd8+ Rxd8 27.Qxd8+ Kf7 Here Black has avoided immediate disaster, but his long-term outlook is bleak on account of White's extra pawns and his own weaklings on b7 and a5.  Nevertheless, this is a stronger line of resistance than what occurred in the game.; The other king retreat 20...Kh6 is no improvement since after 21.Rf6 Qe5 (21...Qe7 22.Ref1) 22.Qxe5! (Black's development is so backward that exchanging queens does not help him one bit) 22...dxe5 23.Rf7 c6 24.d6 Be6 25.Rxb7 Rd8 26.Rd1 Rd7 27.Rc7 Rxc7 28.dxc7 White's c-pawn will cost Black a piece. 21.Ref1 c5 22.Rf6! White's attack has reached maximum strength and, unless I'm missing a miracle defence, Black can no longer save the game. 22...Qe7 Not 22...Nf3+ 23.R6xf3+ winning immediately. 23.Qe3 Qxf6 The threat of a mating attack with 24.Qg5+ forces Black to give up his queen. On paper, he ends up with more than enough for it, but his queenside pieces are so badly jammed out of play that the game effectively turns into queen and pawn versus knight. 24.Rxf6 Kxf6 25.Qg5+ Kf7 26.Qxh5+ Ke7 27.Qg5+ Ke8 28.Qf6 Nf7 29.h5 Bd7 30.h6 Rc8 31.h7 b5 32.e5! Much more accurate than queening the pawn. 32...dxe5 33.d6 Black cannot avoid immediate mate.  A very beautiful attacking game by Pitre, one that must rank among the very best he has played. 1-0
