My dad is a world champion in bridge, and is an ENTJ. Geir Helgemo, the best Norwegian player of all time, and probably one of the best in the history of the game, must be a TP. I don't know if he is a S or N, but his game is very intuitive, but I don't know if it is intuitive in the MBTI sense. Zia Mahmood is another player that falls under the same category, very creative, and I think he is probably ENTP, but these two are perhaps the two most creative players around. Experience is extremely important in bridge, which might be an advantage for SJs. One of my best friends, at least earlier, plays on the Norwegian junior team, and is an ISTJ. Being a T is probably an advantage, and the letter that correlates most with skill.
