To continue the equine metaphor from my previous post, having fallen at the last fence in the Welsh Chess Union Online League, Aberystwyth had to get back on the horse in the next round of the Dyfed equivalent, in another match against Aberystwyth University, this time their B team. Accordingly we fielded a strong team, but the result, though not the whitewash of the previous match, was not as good as we hoped. Rudy van Kemenade used his experience in the Anglo-Dutch to build pressure against Cameron Westwood's weaknesses, first on d3, then on the kingside, and was clearly better when his opponent dropped a piece with a mouse-slip. Adam Watkin-Jones's game against Marcus Perry was another English, which went wrong for White when he missed a tactical point, leaving him material down with a worse position. I miscalculated my chances in another Dutch against Harry Fox, and all I got out of my intended kingside attack was a pawn deficit and a big loss of time. When he blundered just before the end I completely missed it, and made a blunder of my own in return. Tom Gunn won a couple of pieces early on in a Queen's Pawn Game against Patrick Bourne for a trouble-free win. A 2-2 draw was a slightly disappointing result.
