The Preconditions of Attacking a Castled King - Puddletown FREE Webinar
An attack on the castled king cannot be successfully carried out on the basis of the attacker's wishes or 'brilliance' alone, but the essential conditions must also be present. The preconditions are: control of the center; prevention of counter play on the queen side; proper posting of the attacker's pieces; weakening the castled King's defenses. We will discuss these preconditions using examples from classical games.

The Three Questions to Ask Yourself before Each Move - Puddletown FREE Webinar
Welcome to Pudddletown's December Seminar with FIDE master and Women International Master Zoey Tang!
There are two winning scenarios in chess: win yourself or let your opponent lose. You can win a game without showing good play, but it is impossible to win without an opponent's mistake. In a sense, the strategy for success in chess is not to make mistakes yourself (or at least less than your opponent) and force him to do so.
