Hello Suprafix, Unfortunately not many old players still play, and the current Skill level on Four in a row has declined since back in the day.
As for the top Connect 4 players, I will stick to the old players.
- Eliten
- Qwer
- Relfson
- Dreddz
- Petit Couer
- Suprafix
- OwNeD (aka Celestial Knight
- Golbez
- etc etc
the list goes on. The above players are good because they are not only perfect in regular starts but also play a huge variant of Win/Draw styles and win from them. Their knowledge and understanding of the Connect 4 Algorithms is very good, which is why they have been mentioned specifically.
Unfortunately, no one currently playing in the Top list, I can compare to the list above. The skill gap is too big.
