Interference - Chess Tactic

Burn produced the staggering 33...Qg4!!, leaving his queen en prise to three different White pieces. However, if 34.Bxg4 or hxg4, Black wins with 34...Bxd2. If 34.Qxg5+, Qxg5 35.Rxg5+ Kh6, Black wins a piece and the game. MacDonald instead tried 34.Rxg4 Nf3+ 35.Kg2 Nxd2 36.Rxg5+ Kh6 37.h4 Nxb3 38.Rf5 Nxa5 and Burn won in 11 more moves.

Weak Squares

Weak Squares-Weak squares can be defined as squares where your opponent can safely post his pieces. Weak squares provide an entry point into your territory and are often the precursor to an attack. Naturally, if you can exploit the weak squares of your opponent, then they will work for you. (Definition- From "Introduction to Chess Strategy for the novice player" by Bill Whited)
