Interference - Chess Tactic

Burn's Brilliant Queen Sacrifice!

In a stunning turn of events, Burn played the incredible 33...Qg4!! This daring move leaves his queen seemingly hanging, threatened by three of White's pieces! However, this is a cunning trap.

If White falls for the temptation to capture the queen with 34.Bxg4 or 34.hxg4, Black immediately wins a piece with 34...Bxd2.

Another tempting capture, 34.Qxg5+, also backfires after 34...Qxg5 35.Rxg5+ Kh6. Black escapes with a piece up thanks to the king's flight to h6.

MacDonald, realizing the danger, chose 34.Rxg4 instead. However, even after this defense, Burn continued his precise play with 34...Nf3+ 35.Kg2 Nxd2 36.Rxg5+ Kh6 37.h4 Nxb3 38.Rf5 Nxa5. While a pawn down, Burn's strong position ultimately led to victory in just 11 more moves.
