At
Gausdal in 2004, he won the tournament, ahead of
Magnus Carlsen and despite being expected to finish no higher than mid-table. He soon fulfilled the requirements for an
International Master (IM) title, awarded the same year. Becoming a full-time professional, the opportunities for travel continued to suit his lifestyle and in 2005, he complemented his training and dedication with a few good wins, gaining the necessary norms to be awarded the Grandmaster title. During this period, he finished second equal at the Essent tournament, was co-winner of the strong
Karabakh 'B' tournament and scored well at the
Wijk aan Zee Corus 'C' tourney, earning an upgrade to the 'B' tournament in 2006. At the
Turin 2006 Olympiad, he played a small but helpful role in the national team with a very respectable score of 3.5/5. By then, his
Elo rating was reflecting the consistency in his performances and he passed the 2600 mark by the early part of 2007. Working with a new coach (GM
Vladimir Chuchelov) was perhaps another reason for his continued progress. At the
European Team Chess Championship at
Heraklion in 2007, he contributed another plus score (4.5/8) to the Netherlands team total. 2008 was a rewarding year for l'Ami. He finished with a share of second place at the
European Individual Championship in
Plovdiv, missing out on the medals after an eight-way play-off. More recently, he took part in the
EU Individual Open Chess Championship at
Liverpool, maintaining touch with the leading group throughout and finishing with a share of fifth place, alongside compatriots
Sergei Tiviakov and Jan Smeets. He took part in the
Chess World Cup 2009 and was knocked out by
Krishnan Sasikiran in the first round. In 2010, L'Ami helped
Veselin Topalov in his
World Championship match against
Viswanathan Anand. In 2014, L'Ami participated in a
chess.com death match against
Jan Smeets, which he won. In 2015, he won the
Reykjavik Open scoring 8.5/10. In 2022 he won the
Dutch Chess Championship. ==Chess second==
