Hi,
here my pgn from my database.

[Event "NOLOT 05"]
[Site "?"]
[Date "1969.06.04"]
[Round "?"]
[White "Spassky, B."]
[Black "Petrosian, T."]
[Result "1-0"]
[SetUp "1"]
[FEN "r2qrb1k/1p1b2p1/p2ppn1p/8/3NP3/1BN5/PPP3QP/1K3RR1 w - - 0 21"]
[PlyCount "7"]

{Spassky,B - Petrosian,T / Wch Moscow (Rd.19) 04.06.1969 White has an Attack
against black's King, but there's no obvious way to break throught. White
needs the e4 square for the knight to divert / destroy the Nf6.}
