9.d5 Nd8 The knight is hard to regroup from here.[Yip] [9...Nb8 This undevelopment is fine for black.[Yip] 10.Nc3 a5 11.Nd2 Na6= [Yip]] 10.Nc3 Nh5 Clears the way for the f−pawn for normal King's Indian counterplay.[Yip] 11.Qc1 f5 12.Bg5 Nf6 13.Bh6 Nf7 14.Bxg7 Kxg7= Diagram

The all out advance on the kingside creates weaknesses.[Yip] [17...e4 18.Nd4 Ne5 19.Qb3 a6= [Yip]] 18.h4! Immediately fixing the kingside is best.[Yip] 18...Ng4 [18...g4 Continuing to advance does not achieve anything.[Yip] 19.Nd2 a5 20.a3H [Yip]] 19.hxg5 Begins the undermining and destruction of the kingside.[Yip] 19...Nxg5 20.Nh4! The knight is excellently placed on the non−traditional edge of the board.[Yip] 20...Qf7 21.Qd21 A good positional move that reinforces f4 indirectly as black was preparing the ...f4 advance.[Yip] 21...f4?+− Diagram

This is asking too much of the position as black is not well placed to support this attacking thrust.[Yip] [21...e4 Is better but still bad for black.[Yip] 22.Ne2 b6 23.Nf4I The static kingside structure and the absence of the dark bishop make the long−term positional prospects poor for black.[Yip]] 22.exf4 exf4 Diagram

23.Rae11 [Yip] [23.Ne2! Is winning outright as the f4 pawn is lost.[Yip] 23...Kg8 24.Rac1 There is no hurry to take the f−pawn.[Yip] 24...Qg7 25.Nxf4 Ne5 26.c5+− White is up a clear pawn and there is no hope of black breaking



through on the kingside.[Yip]] 23...Ne5 24.Ne41 Strengthens the kingside.[Yip] [24.Ne2! Is still best.[Yip] 24...Nh3+ 25.Bxh3 Bxh3 26.Nxf4 Bxf1 27.Ne6+ Kg8 28.Kxf1I White has a pawn and a dominating position for the exchange.[Yip]] 24...Nh3+ Diagram

Trying to force an attack through where there is none.[Yip] 25.Bxh31 This exchange is premature and black escapes the worst.[Yip] [25.Kh2! Qd7 26.c5 Now the marooned Nh3 is really a burden on black's resources.[Yip] 26...Kg8 27.Qc3 a5 28.cxd6 cxd6 29.bxa5 Ra6 30.Rc1+− Black is tied down completely and the c−file invasion cannot be prevented.[Yip]] 25...Bxh3 26.Ng5 Qd7 Diagram

27.Qc2 Now its is white who is attacking.[Yip] 27...Bf5 28.Qc3 Kh6 29.gxf4 Rf6 Conceding the Ne5 and the game.[Yip] [29...Bd3 Also loses eventually but was the better option.[Yip] 30.Rxe5 dxe5 31.Qxd3 Qg4+ 32.Qg3 Rxf4 33.Ne6 Rxc4 34.Nf3 Re4 35.Nfg5 h4 36.Nf7+ Kh7 37.Qxg4 Rxg4+ 38.Kh2+− The RNN easily outplay the RR.[Yip] 38...e4 39.Ne5 Rgg8 40.Re1+− A powerful demonstration of centralization.[Yip]] 30.fxe5 dxe5 31.Rxe5 Rg8 32.f4 Bh3 Diagram

Arriving at the side was an adventure in itself as the REAC club is near Budai, Laszlo Stadium on the outskirts of Northwest Budapest in district XV. I was fortunate to run into a player who safely guided my to the playing hall and on the way was treated to a background story of two of Hungary's notable soccer players.Budai was a teammate of Puskas who also has a stadium named after him. 'Ferenc Puskás(born Ferenc Purczeld; 1 April 1927 - 17 November 2006) was a Hungarian footballer and manager, widely regarded as one of the greatest players of all time. He scored 84 goals in 85 international matches for Hungary,and 514 goals in 529 matches in the Hungarian and Spanish leagues...In 2002, the Népstadion in Budapest was renamed the Puskás Ferenc Stadion in his honor. He was also declared the best Hungarian player of the last 50 years by the Hungarian Football Federation in the UEFA Jubilee Awards in November 2003. In October 2009, FIFA announced the introduction of the FIFA Puskás Award, awarded to the player who has scored the "most beautiful goal" over the past year.

This in turn lead to the general avoidance of concrete sequences and missing many opportunities.[Yip]

26.f5?5 Wrong plan.



Wrong pawn advance. Wrong everything, and now the game goes downhill quickly. White conducts the game in an overly prophylactic manner and plays against Bd7 instead of considering the thematic plan of the Benoni as a whole. The natural Benoni idea is to advance in the center where the pawn majority is but white has strategic myopia and for this game is incapable of thinking inside the box.[Yip] [26.e5 Is the right idea with the key point being to free e4 for Ne4−f6+ or Nd6.[Yip] 26...Bf5 Black must prevent the Ne4−f6+ idea.[Yip] (26...Qd8 27.Qe3 Bf5 28.g4 Bc2 Active defence is best.[Yip] (28...Bd7 Passive defence leads eventually to massive kingside pressure by white.[Yip] 29.Kg2 A useful prophylactic move.[Yip] 29...f5 Something must be done about the Ne4−f6 idea.[Yip] (29...b5?
