Wel basically, you can traduce a 3v3 match with a "psychologic fight" in first, and everything on stats that are showed as disadvantages can be used in your own team advantage (you have less kills? then you spawn more and have a stronger defense // you have less flags, let the opponent's think they are winning already and then try to surprise them) but all this doesn't always work, there is no ultimate strategies, plus I'm not sure Legacy were following the 2nd last rule.
A 3v3 CTF is not interresting if both teams don't take any risks to win or to take a flag, when your teammate dies, don't come back and defend his side, just because everyone can do that, do you imagine all matches like this? No, let him spawn and face to face the opponent one more time (it doesn't work on small maps like ac_gothic ofc) just try to progress on your own lane and take the flag, anyway, naturally, the opponent who killed your teammate don't want to kill you directly, he will try to take your flag because killing you would just make you spawn with 100 hp, in your base. If the opponent comes back to kill you, well it's a retard, or maybe the opponents are winning with a huge and safe gap.
You have to know how smart are your opponents before the match starts, you have to know who will go left/right/mid and the general behavior of each players (if he's a good fragger, if he plays sneaky, if he rushes the flag and let the opponents going to your base) Of course, I would not let someone taking my flag, but if it allows me to grab the enemy flag and to go away with it, well something interresting will happen, and the real strategy will be in the anticipation and the improvisation of each teams, the flag-owners who dies first is not always the loser, it all depends of both teams strategies, those strategies can not be written on a forum, it just can be played in matches.
