Touching wood is generally all part of the game as far as chessplayers are concerned, but with competitive chess having moved online I had better make a special effort to touch some when reporting that Aberystwyth is still doing very well in the Under 1800 section of the Welsh Chess Online League In Round 4 on Tuesday 10th November we played the other leading team, North Cardiff Panthers, who were ahead of us on game points but like us had won every match. I thought I saw a quick win against Callum Smith's Pirc, but had to withdraw in confusion when it didn't work out. After that I had a long defence, tied to a weak pawn, but Black weakened his position trying to break through the solid centre and I regrouped for another unlikely win. Julie van Kemenade didn't manage to get her kingside counterplay going against Ellison Smith's queenside pressure in a Giuoco Piano, having to castle kingside not only slowed her down but left her vulnerable there too, and White overran her position. James Cook uncharacteristically sacrificed a piece early on in his Ruy Lopez against Bence Szakmany; it turned out to have been a mouse slip, but he did the right thing by keeping his pieces active, pushing his passed pawns and seeking to confuse matters, till his opponent lost his way in the complications. Sam Holman, heavily outgraded against Alun Smith, played vigorously in on the Black side of an Alapin Sicilian, and had good chances most of the way through a complex game, before the loss of a pawn allowed White to reach a won ending. A 2-2 draw means that we are still undefeated at the top of the League - touch wood!
