His firstOlympiad appearance was for Russia at theMoscow event in 1994, when he took home a gold medal in celebration of the team's winning performance. He played for the Dutch team at each of the events held from 2000–2006, with an overall record of +14 −2 =33 (62.2%).[7]

Tiviakov andBogdan Lalic both claim to have playeda previous record 110 consecutive tournament games at classical time controls without losing, although neither player faced exclusively elite-level opponents during their unbeaten streaks and faced predominantly a mix of weaker professional and club level players while playing open tournaments.[8] Tiviakov's streak occurred between 28 October 2004 and 27 September 2005. The current record belongs toMagnus Carlsen (+42, =83), who went unbeaten across 125 consecutive games between 31 July 2018 and 9 October 2020.. While still holding the record, Tiviakov saidDing Liren's 100 consecutive games without a loss against elite-level opponents in 2017–2018 was a comparison ofapples and oranges.[9]
