Chess involves no luck, because you both start with a set board and choose how to play from there. Of course, you may be lucky in the sense that your opponent couldn’t sleep well last night because the neighbour’s dog was barking. Or that he accidentally ate stale food and has a stomachache while playing. But other than that, it’s all about ability and concentration. I think Bridge is also like that. Even though there is a certain amount of luck involved, it is basically a game of strategy. And for me even backgammon is not really luck. Unless your opponent is extremely lucky, clear and strategic thinking can help you win in 90% of situations, regardless of roll.
