diagonal: Happy birthday to your 25th anniversary!
Nils Grandelius is born June 3, 1993 in Lund. He became an International Master in 2008 and a Grandmaster in 2010.
In 2008, Grandelius took clear first place in the Olomouc Open in Czech Republic; thanks to this result, he also achieved his first GM norm. In the following year's edition, he placed equal first, placing second on tiebreak, and gained the second GM norm. He achieved the GM title by earning the third and final norm in the 40th Bosna International Tournament (Open) in Sarajevo, being also the first among juniors.
He won the bronze medal at the 2010 World U-18 Championship, and won the 2011 European U-18 Championship.
In 2012, he placed equal third (fourth on tie-break) in the World Junior Championship in Athens.
Grandelius made a sensation by winning the traditional Abu Dhabi Open 2015. A victory that shows his potential: He took the 22nd Abu Dhabi Masters, edging out on tie-break Martyn Kravtsiv, Baadur Jobava, Alexander Areshchenko and Richard Rapport.
The same year, Nils Grandelius won the Swedish Chess Championship 2015 by defeating Emanuel Berg in a playoff match (they both had tied for first place at 6.5/9).
Grandelius has been playing for the Swedish national team at the Chess Olympiads since 2010 and at the European Team Chess Championships since 2011 in most editions.
Grandelius placed =1st together with young Rapport and chess-veteran Short in a three way-tie at the Sigeman & Co. tournament already in 2013, and was co-winner again in 2017 together with Baadur Jobava from Georgia, and last month in May 2018 together with Santosh Gujrathi Vidit from India.
After the 2018 Malmö TePe Sigeman tournament, Grandelius achieves now his personal peak Elo and <the highest nominal Elo rating of any Swedish chess player since FIDE introduced Elo lists officially>, but he is still ranked outside the Top Fifty.
Note, Ulf Andersson, with a lower nominal peak Elo rating than Grandelius, was peak ranked as clear no. 4 of the world in 1983, then with a rating of Elo 2640; he much later made his nominal peak rating of Elo 2641 in the year 2000, then ranked as no. 40-something.
Stahlberg was historically peak-ranked no. 3 in chessmetrics.
Stahlberg, Stoltz, and Lundin were called "The Three Swedish Musketeers". They established their names as world players at the Chess Olympiad in Folkstone 1933 and Warsaw 1935 where Sweden took the Bronze and the Silver medal respectively!
These Three Musketeers were prominent on international circuit from the 1930 to the early 1960s, certainly the best players, the Swedish Federation had to offer then, until the world met... Ulf Andersson :)
Time wille tell, how Grandelius can evolve. All the best to him.
