of course I knew, and indeed it was on top of the headlines for couple of days, even though most headlines here belong to an Italian guy Stramaccioni in past couple of weeks
Firouzja didn't talk to any media about this. so we don't know his exact reason but forcing to withdraw against Israeli opponents is probably one of the reasons.
after Judo now we are in trouble in Chess, apparently until 2019 it was a rule you could use to avoid whoever you don't want to face in Swiss table. FIDE changed that rule and that's when the problem started ! last week two of our players (Iran's #2 and #3 Maghsoudloo and Tabatabaei) were in a tournament in Spain and they both faced and beat an Israeli opponent !! they both claimed they didn't know the guy and it was a blitz competition without a flag on the table next to the players. that caused some "problems" here, and therefore Iran decided to not participate in the World Rapid/Blitz Championship, (or at least not sending a male team, there will be female players from Iran)
and that's when Firouzja revealed his old plan, he was living in France for few months and we had rumors he wants to eventually switch nationality, this accident probably forced him to do it sooner. so I can say this is probably not directly related to Israel but that was one of the reasons. this is different than Mollaei, this is his right to live wherever he wants and unfortunately he prefers somewhere else. Mollaei is a cheating liar.
The truth is this is not really surprising, he is considered a great talent and the situation in Iran is really bad these days. mostly financially, these guys had to pay for their expenses (tickets, visa etc) another thing is 10 years ago it was considered VERY BAD , treason or something like that but when something happens again and again this is not "bad" anymore. and unfortunately I won't be surprised to hear news about this again in the future.
