{It is a common occurance in Open tournaments to see quick draws on the top
boards, assuring the players a decent prize money and a good feeling for
finishing on a positive note; the risk that playing all-in brings, is too much
to bear for most players: the stakes are high, the round is usually played
earlier so less time to prepare, everybody is tired, all in all it is a pretty
difficult psychological affair on which dozens of articles have been written
already, whether to allow such draws or not. That's why the 30 moves rule
appeared and also the Sofia rules...but in the end, this is the chess players'
job, to bring home the bread, so risking it is not for the faint hearted. This
game, both Nigel and David proved they are lion-hearted, as they sat down and
played each move to destroy the opposite side! And soon a similar Benoni
structure appeared on the board, the only difference being that David's bishop
was out for a walk on b4 and not placed as usually, on g7. We know what
happens in such slippery battlegrounds...fire on board!} 1. c4 Nf6 2. Nc3 e6 3.

Nigel was trying to exploit, in his concrete and dynamic style that we have
already seen glimpses from the previous game against Sargissian. And yet,
there was a tactical and positional, at the same time, trick that he missed
after:} 22. Nh5 b3 $1 {Well timed, preventing White to exchange it via a4 and
thus the white bishop is downgraded to a pawn's life...} 23. Bb1 ({Nigel said
he missed this little move, so he decided to retreat the bishop; and I also
wanted to write down that taking on b3 is out of the question, until the
moment I switched on the engine...and it is not that clear!} 23. Bxb3 Bxe2 24.

computer game? It does...first lines of my engine. I didn't let it run for a
long time so certainly these are not forced moves but just to get an idea of
what's happening. And I am not sure what's going on, such a pawn on c4 is
rather scary, so there is no surprise a human would chose to safely store his
bishop on b1, to start with...}) 23... Kh8 24. Rf4 Rg8 25. Rh4 Rg5 26. Ng1 {
Black seems to have stabilized the attack, the knight is still enjoying his
forever lookout point and it should go his way from now on had he prevented
the last deadly sleight of hand.} c4 {Oups! It didn't...the second push of a
pawn was only a flash in the pan, as it fails to what brought Nigel the
tournament's victory! Can you find it?} 27. Rxa5 $1 {distracting the queen
from protecting the king of the house...} Qxa5 28. Nxf6 Kg7 29. Nxh7 Rh8 30.

position is truly impressive, no chances are handed Black to come back in the
game.} Kxf6 32. Rxh8 Nf7 33. Nf3 Rg3 34. e5+ dxe5 35. Rh6+ Ke7 36. Rg6 Rxf3 37.

wonderful for the spectators to have seen a tooth and nail fight for the first
place and the 6000 pounds...not sure it was the same for David, who still had
a great tournament after all, but losing in the last round is somewhat leaving
a bitter taste behind. In any case, money, rating, it will all come back
eventually and we are left with a beautiful fight for which we thank both! And
we congratulate Nigel once again for his performance!} 1-0
