In making notes on games, I've probably explained lots of chess mistakes, and why they were mistakes. I might say, this Black move is a mistake, because White now plays A, and this works because if B then C and if D then E. (Or, White should have played A, etc.)
But there is another side to each mistake, which I can't tell anything about, but which perhaps you can, and you should try. A mistake in a chess move is also a mistake in thinking.
A tale of three discoveries: a discovered attack proved the winning move in all three games.
Unmasked threats - discovered attacks and discovered checks - are the
most difficult threats to spot. You pay attention to the piece that
moves, but the threat comes from the piece behind.
I've attached a discovered attack training page - get your eye in! In 2010, the Devon U14 team lost an awful lot of points (or a lot of awful points) to discovered attacks, and the puzzles are all things that they missed.
A squad that fought its way out of Exeter's heavy traffic to visit Newton
Abbot emerged victorious to retain the Peter Rooke Cup.
Despite some late substitutions, the teams were roughly balanced with
Teignmouth looking stronger on the higher boards, so Exeter were looking
for points in the bottom half. In the event, the closing stages saw
Newton Abbot's lead on the lower boards overtaken by a couple of
last-minute wins for Exeter higher up the order.
