Mundwiler - Liu 1-0
Liu, with 15...Ne4, forced Les into a winning combination that culminates in 20.Nd5 (classic theme usually seen in Sicilians.) Incidentally 25. Qd7 would have also resulted in white's King also walking to g6. The way Les played it, the King gets there one move earlier.
Czypinski -Oberton DRAW
The opening was quite quiet but 24...f4 leaves a weak backward e pawn
But play continued 25. Ne4 Nxe4 26. Rxe4 Bf5 and Black keeps the material balance; a drawn Rook and Pawn endgame resulted.
However, after 25. Nf1, the epawn will fall without much fuss.
Silva - Kong DRAW
A
very interesting endgame arose after 50. Kxd2
Upon first glance, 50...Kc4 looks natural. 51. Kc2 is forced. Then 51...a5 52. b3+ Kc5, I think White is lost. Black has two main themes: a5-a4 which creates a hole at c4; and the fact that he can create a passed pawn, likely the e-pawn. Take a look, it is great study material, post a message if you have any thoughts.
Kong played 50...f5 which is a little hasty...the availability of having moves like f6 and f5 in reserve can make the difference in endings like this.
Later, this position occurred--White to move.
Silva played 57. f4 ! (although he should have played it on his 56th move)
So the following position arose after 62...Kxa3
Almost anything wins here, including bringing the king over to the queenside and mating, but most of us would pick off some pawns first. Disregarding the quick mating variations, the only thing to prevent is the advancement of the a pawn; the kingside pawns aren't going anywhere.
In the game, 68. Qd4(which was not played) is instructive as it is an easy way to stop the a pawn.
I believe the last chance for White to win was after 72...f3+
73. Ke3 ! Kb1 74. Qb3+ Ka1 75. Qc2 ! the point as there is no stalemate ...f2 76. Qc1 mate.
It was a long game, so time trouble was probably a factor.
Greenberg - Khedkar 0-1
I think it was Jack Woodbury who cautioned me about playing Bf4 "on top" of a fianchetto. Now I am passing that wisdom on to Harley.
Wierda - Aaron Green 1-0
Wierda gives Aaron a knight on move 7, but by move 20 he has 3 pawns for it. Aaron could have regained his advantage with 21...Qxc4, or 28...Qxa5 but did not and lost on move 30.
Rutter - Atem 0-1
Blair made a strategic error by playing 21. bxc4 instead of Rxc4. The open B file immediately gave black tons of obvious play. Well played by James.
Jim Green - Saul Magnusson 1-0
White had a small edge until black hung an exchange in the middle of the board.
