Alright, probably not fixed but someone most have know something to put such big money on a player that is very unreliable who has just been broken and when its still on serve in the 2nd set.
Don´t think so. Maybe the guy wanted to green out after having laid Korolev at 4-3, lost his connection or just was pissed off and wanted to trade out with a smaller loss on both sides, if u want more possible scenarios I might write a few more.
Gicquel maybe had no intention of winning this match? Not sure.
Unlikely, as Gicquel has played his best tennis in these small French indoor tourneys, no reason to throw a match like this
