Xu "fy" Linsen is a professional Dota 2 player who is currently playing for LGD Gaming.
Although a relative newcomer to the Dota 2 scene, fy has found immediate success in the professional scene. Fy is often considered to be the best Rubick player in the world, and he and former teammate Fenrir were known as one of the top support duos in the world and the main driver behind the success of Vici Gaming.
2012-2015: Beginnings with Vici Gaming and TI-runner up
Fy first made his appearance in competitive Dota 2 when Vici Gaming was created on the 21st of October, 2012.  It was believed that it took numerous attempts to persaude fy to come to VG despite not having played a single match of Dota 2, but a person called "WarGod7" convinced him to join the team and eventually become a player of VG as a support. Fy described his move to Vici Gaming as "fate".  He played alongside with cty, fenrir, xtt and sydm - the four remaining players in the Dota 2 squad alongside their team manager/team leader Panda Pan Pan also known as Fengdidi.
Vici Gaming failed to find some form in the first half of the 2013 calendar year as they were eliminated in the groupstage or the first round of the playoffs in many domestic tournaments such as G-League 2012: Season 2 and Dota 2 Super League. More importantly, they fell short in the The International 3 Eastern Qualifiers, losing to LGD 3-0 in the grand finals.
Despite the heroics of fy's favorite hero, Rubick, during G-League, it was inevitable that after disappointing results there would be changes within the team. On the 10th June, 2013 it was understood that fy and xtt decided to leave them team. However, it was later revealed that fy left without authorization and was forbidden from playing with another team until his contract with Vici Gaming expired. Despite the warning given to fy from his management team, he still was determined to leave Vici Gaming. The next day saw a sharp turn of events when fy decided to come back to Vici Gaming after unoffically leaving the team, as he wrote a personal statement on his Weibo: "Today, I had a talk with VG investors and found out a lot about stuff that outsiders didn't know about. I express my regret that I have misunderstood someone and has decided to stay in VG and fight with my team. I apologize for my decision before and I hope everybody continue supporting VG." Thus, fy's position in Vici Gaming remained unchanged while xtt offically left the team, leaving Vici Gaming on the lookout for a carry player. After the fallout between fy and VG, the team saw further changes with cty leaving, Super and rOtk coming in after ZSMJ's exit, and Sylar's controversial replacement of TuTu.
In Vici Gaming, Fy is like DiMaggio to AC Milan or Totti to Roma. He's like Vici Gaming's Symbol, Vici Gaming's face.Xiaoyun Xu, Vici Gaming's team manager on fy in July 2015 
After several months of instability within the team, Vici Gaming were invited last minute to the LAN event finals of ESL Major Series One Fall Event in Tychy, Poland when Team DK's visas were denied. This event showed the awakenings of the renowned Fenrir-Fy support duo; fy displayed his virtuoso talents as a rising support star throughout the series and won the tournament MVP award after Vici Gaming defeated Fnatic 3-1 in the grand finals. This was also fy's first LAN victory and his first Victory away from mainland China. After the event, an interview was conducted with fy where he said the decision to stick with VG was the right choice and that he believed his 'bond' with Fenrir exists because of how close friends they are outside of the game.
Despite playing primarily support for VG, fy has won two 1v1 tournaments: The ECL 2013 Dota 2 Season 1v1 tournament in July 2013, beating the likes of ZSMJ, BurNIng, and cty , and the For a Few Tangoes More 1v1 tournament at The Summit 1 2014, beating amateur Excalibur and Funn1k.
2014 saw a good year for fy when he and his team were invited to The International 2014 by Valve via direct invite. With Vici Gaming, he placed 2nd at The International 2014 falling short in the grand finals losing to Newbee 3-1. While coming 2nd in his first International, he mentioned it was a pity but was later optimistic that reaching 2nd place was a great achievement for his first time. He used his prize money from the tournament to buy his mom a new house. After the 2014 TI shuffle, rOtK retired and fy was made captain and drafter for the team. He highlighted that he had faith with his team despite the addition of Black^ who could not speak Mandarin. He captained Vici with victories at ESL One New York 2014 and The Summit 2. The following year, Vici placed 2nd at the Dota 2 Asia Championships and 4th at The International 2015, where he was featured in a player profile by Valve. 
2016-present: Vici-Gaming Reborn and second stint with Vici Gaming
On the 19th of March, 2016, Fy was moved to Vici Gaming's secondary squad, Vici Gaming Reborn. He won his first tournament under his youth team beating Natus Vincere 3-1 in the StarLadder Invitational 1 despite having his coach Mikasa playing as a substitute for the team. Following the event, he finished in the top eight for the Manila Major 2016 but was eliminated in the first round of the lower bracket during The International 2016. He later moved back to his primary squad, Vici Gaming on the 14 September 2016.
