as salam alaikum
there are many ahadith forbidding playing chess for the believers and that is why most of the scholars have forbidden it. Other scholars have deduced that the prohibition is related to gambling and not to all cases of playing chess. There are relatively lengthy discussions on the topic and opinions are different in this regard.
In such cases, precaution is the safest option and more in harmony with the apparent meaning of many ahadith. And Allah knows the best.
With prayers for your success.
