Rest days: 10 June (adjourned games), 11 June (visit to USCF CHESSathon at Grand Central Station) and 15 June (adjourned games). The pairings had been announced in early February 1994.

"This was the closest match of the four. Although Adams is rated higher and generally thought to be the stronger player, Tiviakov had enjoyed nothing but success against him, winning both their previous games. But Adams came out swinging by winning the first two games, though Tiviakov did not get demoralized, and bounced back by winning the next two. In round five they drew, marking the first time in their seven games that they had a peaceful result! In the next two rounds they again traded wins, and then in a tough eighth game agreed to a draw, thereby going into the playoff. It is interesting to observe that although they could almost not do anything except win or lose their slow games, in the faster games of the playoff they could only draw! Four times they drew their games, until in the fifth game (played by now at game/15), the nervous tension took its toll. First it seemed that Adams would win, as he quickly outplayed Tiviakov and built up a winning position. Then a combination of resourceful defense by Tiviakov and nervous mistakes by Adams brought a complete turnaround, and after missing several clear wins, Adams wrecked his position and entered a clearly worse endgame of two rooks versus rook and two bishops. Still, the pawn structure was very unbalanced, and both sides had problems to solve. Adams put up a tough defense, and when Tiviakov nervously blundered one of his bishops, he brought the win home to take the match." (Wolff)
