I'm learning poker while on a break with my son, we've learnt Texas hold'em
is that the most popular variant? or should I know of a more popular version?

Not poker, but 13-card rummy and teenpati are my favorites. The rules depend on who you're playing with, like billiards.
Poker is a wonderful game involving many disciplines. It's an invaluable skill to have as a bitcoiner. I'd suggest you start with the 5-draw. Imo that's the classic version.
