I often get asked how to improve your chess playing ability? Well, apart from the 10,000 hour rule (if you want to be an expert at anything, then you need to put in that many hours! – see Malcolm Gladwell’s Outliers), then a structured practice and training regime is also useful (sorry, no short cuts here). Pattern recognition and learning can also help.
The following link (a 3 page pdf file) gives a few good points for when starting out in chess, that covers basic techniques, planning your game, time management and how to survive a day of rapid chess: a-beginners-guide-to-chess.
Also, parents often ask how they can help their child – please see coaching-tips-for-parents for some guidance.
