A lot of poker game tournaments have been announced on this board over time, and am I kind of wondering what makes poker games so inclined to the tournament and we don't see such competitions being announced for other games?
I do think that it is highly because of the nature of the game itself.
Unlike other card games such as blackjack, etc., they fairly end quickly and the process is relatively simple compared to the techniques involved in poker. In addition, poker is one of those card games that mix luck, skill, and technique in order for you to win the game. Either you win due to the overwhelming card quality that you have on the pool, or because you bluffed the opponent even if your hand is bad.
BlackJack requires some skill to win profitably too, but it's a different set of skills from poker. In poker, I believe it's a mix of math, probability and psychology because you are also playing against another player. In BlackJack it's more on just the math and probability, but it can be a good card game for tournaments.
There's another casino game that requires skill to win profitability, and it's like BlackJack because it's more about just the math and probability. It's the dice game called CRAPS. Every gambler in the forum should play it.
