Alright, you have to set the owner of the turf AFTER the player has captured it, so following your code it would be

pawn Код:

public GolfTurfT(playerid)
{
    TurfOwner[GolfZone] = playerid;
    GangZoneStopFlashForAll(GolfZone);
    GivePlayerMoney(playerid, 9000);
}

And then check before the player initiates capturing

pawn Код:

if(checkpointid == GolfCP)
    {
    
    if(TurfOwner[GolfZone] == playerid)
           return 1;

    SetTimerEx("GolfTurfT",9000,0,"i",playerid);
    GangZoneShowForAll(GolfZone,GetPlayerColor(playerid)); //Old color 0xFF71B896
    GangZoneFlashForAll(GolfZone,(playerid));
    }

Consider making protection, if there's more than one person in the turf it will be captured for both.
