The problem with chess has always been that there's no luck element. You can't hustle a game with no luck element very effectively because the fish needs to win sometimes. You can throw a game now and then to keep the fish interested, but you're walking a fine line because if the fish finds out what you're doing they not only quit playing you but become quite upset. (I've done this playing $1 games downtown and it tilts 1700 club players to know that they're only beating me 1 game in 4 because I'm letting them.)
So how could we alter chess slightly so that it became, say, 90% skill and 10% skill? I've seen variants where
cards are used and whatnot, and there's even a variant somewhat similar to poker in which your opponent can literally buy takebacks from you, and another in which you make $x for every enemy piece that you capture (called, of course, "hold em"). I can't find this variant anymore, so no link.
Just some wistful thinking on my part. If chess were altered slightly and suddenly fish were willing to play for money, I'd feel that a large chunk of my life hadn't actually been wasted.
