  SwitchingQuylthulg: Like many Finnish players, Ristoja has a keen tactical eye - overly keen, at times... Here are some of his worst combinations, unfortunately missing from this database:

Jan-Michael Nykopp vs Th. Ristoja, Helsinki 1977. Here, Ristoja was up a rook, and 44...Rc3 would have won on the spot, and 44...Qc3 with all probability a bit slower. However, Ristoja's 44...Qf2+ 45.Kf4 was also OK as 45...Qe3+ 46.Kg3 would give him another chance for ...Rc3. Instead, he saw an immediate mate: 45...Rxe4+?? 46.Kxe4 Re8+. The idea was 47.Kd3 Re3+ and mates, but... 47.Kf4! going back. He still had a draw but, being shocked, blundered even that and lost the game.

A case of total blindness: Ilkka J Saren vs Th. Ristoja, Helsinki 1976. 12...a5 and 12...a6 should both give Black an OK position. Instead, he saw something more interesting: 12...Rxc4?? 13.Bxc4 and resigned. Suffice it to say the idea was 13...Qh4+ 14.g3 Qxc4 with counterplay for the exchange, but there's a little obstacle in the way.
