In 2011, GM Sambuev won the Canadian Championship (tied for 1st-2nd with Eric Hansen and won the 2 game rapid tie-breaker match) after he moved to Montreal in 2007 to teach chess. He won Zonal 2.2 (Canada) to qualify for the World Cup (2013) but was knocked-out by Alexander Morozevich of Russia in the 1st round tie-breaks after he managed a surprise win in the regular time control. In 2012, he won the Canadian Championship outright with 8½/9 and also tied for 1st-2nd with Leonid Gerzhoy in the 2011 Ontario open. He again won the Canadian zonal in 2017 for a 3rd time since 2007 (only 6 such events were held between the period of 2007-2017) when a previous Canadian champion Noritsyn became runner-up this time once tiebreaks decided the winner of this cycle(12).
He tied 1st-2nd at PWC Toronto Open (2009) with Joshua E Friedel. He tied 1st-3rd with Merab Gagunashvili and Anton Kovalyov in the Quebec 2010 Invitational and won the Ont. 2010 Open and Eastern Ont. 2010 Open respectively with 5/6 and 4½/5. He won the Hart House Winter Holiday open tournament outright with 4½/5 in 2010. After giving a Friday night simul for the city in 2011, a perfect run of 5 straight wins in a Winter (swiss) open tournament in Hamilton saw him edge out Nikolay Noritsyn, Artiom Samsonkin and visiting Wesley So along the way. In 2012, he and Noritsyn tied for 3rd-4th in Guelph's Winter Open, and he has won both the Ottawa and Kitchener (the latter is now known as the Riedstra memorial tournament) Winter Opens, each time with a perfect streak of 5 straight wins in the rounds. He has also scored well in the GTCL, EOCA and SWOCL series of weekend tournaments and league standings hosted in Ontario.
On other stages, after the 2013 World Cup, Bator also tied for share of 14th-24th at the Isthmia open in Greece and signed up for the Edmonton International(9) in June, 2016. He won the 2016 Carnavale de Québec in February (ahead of Hansen, Thomas Roussel-Roozmon, Steve Bolduc, Aman Hambleton, etc) and scored 5.5/9 behind winner Evgeny Bareev (equal with Razvan Preotu, ahead of John Fedorowicz with 5/9) at the 2015 Kitchener masters' tournament. At the 2014 Gatineau open, Jean Hebert and Sambuev drew in the 2nd last round to lead the tournament and placed 2nd at the Championnat Ouvert du Québec(10).
Team play
Nearing the end of 2016, he (as well as Thomas Roussel-Roozmon, who do not live near Toronto's suburbs) signed on as a free-agent of the Toronto Dragons(11) professional chess league (other players include: Gergely Szabo, Razvan Preotu, Nikolay Noritsyn, Kaiqi Yang, Arthur Calugar, Michael Song, Shiyam Thavandiran and Raja Panjwani on their team).
At the Chess Olympiad (2012) he represented Canada's top board (in 9 of 11 games played, he registered 3 wins and 6 losses) and confirmed his invitation to again represent them‡ at the Chess Olympiad (2014) (+5-3=2 on 4th board).
