They are different games, it is not even possible to make any association and comparison. Poker is a card game that combines skills and luck. Chess is a board game where each piece has a function and objective.
In poker you can play between several people, and chess only one on one.
You can compare chess with queen, then you are being coherent. It will also be coherent to compare poker with other types of card games, such as Black Jack,
baccarat, truco, hole, among others.
Comparing poker and chess will be the same as comparing a duck with a fish, although they both swim, one is a bird and the other is an aquatic species.
