Nah, teach your kids chess, so that they can exercise their deductive/calculating muscles during that golden phase of childhood in which our brains are malleable enough to easily learn new languages: realize that artificial languages (i.e. deductive systems) are all functionally equivalent, and use chess as just another avenue into building deductive fluency; use multiple such avenues (e.g. music, Euclid).
Call this educational stage "deductive naivety": the child will become good at applying logic to their experiences. They will, shockingly quickly, outgrow this phase, and realize that the world does not lend itself to deduction in all cases. Now we can introduce nuance, distinguish between deductive/inductive/abductive reasoning, and start to introduce the child to the multivariate dimensions of the world.
In this way, the child becomes a curious and rigorous thinker. If you choose poker instead, you'll just breed a gambler.
