Behind in Development premature activity by black will backfire.16.Nxe4 d5 17.Bxe7 dxe4 18.Ba3 exd3 19.cxd3! Opening the c-file and eyeing the e-pawn Qc2 20.Nd4! and now
A.) 20..Qd2 21.Nf3! Qxd3 22.Rad1 Qc4 23.Qg3 and white is better
B.) 20..Qxg2+ 21.Qxg2 Bxg2+ 22.Kxg2 exd4 23.Rae1+ Kd8 24.Re7 ]

16.Rae1 Qb8 17.Bd2 Qa8 Black is overloading on the e4 square,x-raying to the g2 square and preparing the exchange sac on c3.18.Qg3 h5 (ambitious plan indeed!,idea is to open the h-file and the long diagnal a8-h1 by exchanging on g2 18..Rg8 is interesting also.)19.Bg5(19.Qxg7?Rg8 20.Qh6 d5! and black breaks thru) h4! offering a pawn 20.Qh3!? (White can take the pawn but black may find compensation in the open h-file [20.Bxh4 Nh5 21.Qg4 Nhf6 22.Bxf6 Nxf6 23.Qe2 Nh5 24.Qf2 Rh6 25.Nd5 Bxd5 26.exd5 Nf4 27.Be4 Nh5 28.a5 Nf6 29.Bf3] Rxc3!? sticking with the plan![20..Rh5! 21.bxf6 Nxf6 22.Nd2 Rc5 23.Bc4 Qc8 =] 21.bxc3 Nxe4 22.Bxe7 Kxe7 23.bxe4 Bxe4 24.Nd2!?(Re2 or Rf2) Bd5!?
(Staying on the diagnal is understandable but why not Bxc2?Well the c2 pawn is weak anyway and black wants to maintain pressure on g2,but a deeper look at the move shows that the Bishop on c2 not only wins a "out of play" pawn but it pressures whites f5 pawn.So here the move may be good 24..Bxc2! 25.Rf4 Rh5!

Now the benefits of Bc2 can be seen as there is a double attack on the f-pawn 26.Nf3 Qh8 27.a5 Qh6 28.Rxh4 Rxh4 29.Nxh4 bxa5 30.Qg4 nc5 31.Nf3 Kf6 32.Qc4 Bb3 33.Qg4 Bd5 34.c4 and black is better.)25.Rf4 Kf8 26.Rxh4 Bxg2+ 27.Kg1 Rxh4 28.Qxh4 Nf6 29.Qh8+ Ng8??+---- loses the thread of the position,but it is difficult anyway Ke7! 30.Qxa8 Bxa8 31.Rb1 Nd7 32.Nc4 Be4! 33.Nxb6 Nc5 34.Rf1 give chances to live.Unclear to me is the line Ke7 30.Qxg7! Bb7 31.Re3 Qe8 and the passed h-pawn will be trouble.) 30.Re3 (also f6! wins more dramatically but the threat is the same Rg3) Qd5 31.rd3 Qc6 32.Rg3 Bd5 33.Qxg7+ Ke7 34.Qxg8 Qd7 35.f6+ 1-0

1. Dr Okey Iwu: Dr Okey Iwu with a 2175 rating drew 6 of his games, had 1 win and 1 loss. Any Chess player will tell you this is a remarkable record especially when most of his opponents were higher rated players ( FM Todd Andrews 2360 and James Critelli 2348). He also drew against Charles Riordan 2350 and Eugene Yanayt 2356 among others. His only loss was to Fide Master Daniel Rensch 2448 rating. This results goes to confirm once and for all that Iwu who was a Junior Chess Champion in Nigeria in the 90s is a stronger player who should be in the 2300 category rating and not the 2175 he is now. Watch how Iwus ratings will improve dramatically as a result of this event.

2. Chikwere Onyekwere: Nigerian Champion 21 year old Chikwere Onyekwere, 2267 rating who lost the match in Houston to Nigerian International Master Adu last week also proved himself worthy at this event. Chikwere won 4 games, had 2 draws and 3 losses. Three of his losses were against some of the highest players in the US and in the world - 2 Grandmasters- Kamsky 2752 rating ( Kamsky is no 19 in the world and no 1 in the US as at August 2006 : and Dmitry Gurevich 2591 and 1 international Master (IM), Peter Vavrak 2464. His impressive wins were against IM Timothy Taylor 2388, who has lost to chikore twice now, drew against Fide Masters (FM) Joseph Bradford 2475 and Holger Schacht 2328. As always, many chess players are starting to pay attention to Chikwere. His future is bright in the International Chess Community.

3. International Master Oladapo Adu: The winner of the ADU - ONYEKWERE MATCH in Houston came late after 4 rounds of the event. He was given for 4 BYES = 4 1/2 points each so he could join and begin in round 5. He finished with 3 draws , 1 win and 1 Loss to IM David Vigorito 2419. This is another impressive showing despite his lateness to the event.

We congratulate all of them and look forward to more great tournaments in the future.
