Blind man's bluff is a lot like any other games of poker, but with an intriguing twist. Players can see the hand everyone else has, but cannot see their own. The game is for true gamblers because while you can sort of gleam your chances based on your opponent's hands, any bet is risky.
Poker is about people, not about the cards. You can try and win at poker using a very disciplined, mathematical approach, but that style of play can often be taken advantage of by players who know how to read people. Being able to bluff, and spot when other people are bluffing, is necessary to really enjoy--and be good at--poker.
