Target Chess

In the early stages of a chess career, tactical games dominate. Hardly surprising, as tactics are based on clear goals and rewards, and can be tested with a "it works or it doesn't" condition. One of the simplest ways to play these sort of games is to choose a target in the opponents position and zero in on it. Done well, you can even change targets until your opponent can no longer defend them all.
In the following game 8 year old Ethan Derwent targets d6, then f6 in his opponents position, keeping experienced player Peter Murphy on the defensive throughout. Eventually Peter loses material before finally missing one last tactic.
