Do aliens play poker?

They must do?
If they are carbon, sentient, and functioning in this exact time/space dimension then they have very likely acquired at least some basic understanding of maths and physics. It is not far from there to game theory and games based upon randomly generated probability. Game theory IS nature and bound to be mapped out by anything following a similar evolutionary path of self-awareness using SCIENCE.
It might not look 100% exactly like Earth poker, granted. You’ve got to imagine there are some nuances that would apply across the infinite vastness of space and time. [Maybe they got rid of Jacks??]. But nonetheless a variant of nash based decision making using easily available materials that would also be relatively easy for poker players to learn and map out if they ever get the intergalactic memo.
Even if the best of the best (Bilzerian level) would be total cosmic fish versus their opponent species’ game. And vice versa.

There’s a lot of assumptions going on here.
I’m borderline serious though.
