I play both. I'm an Expert in chess, Bronze Life Master in bridge.
They are 2 completely different games. You screw up in chess, it's your own fault. Bridge requires accurate play by two players. You mess up, your pair messes up. Your partner messes us, your pair messes up.
Chess, on a loss, loses you rating points. Bridge you either gain points or get nothing. Once you have them, you can't lose them. So some "Life Masters" are only life masters due to frequent play, and aren't very good. I play sparringly, and am still under 200 Master Points away from Silver Life Master.
In some ways, the games are extremely similar. Chess has opening theory, Bridge has bidding conventions. Chess has simple tactics like the fork and complex tactics like the windmill. Bridge has simple tactics like the finesse and very complex tactics like the squeeze play, or even worse, the double squeeze or triple squeeze. I have only "conciously" executed the simple squeeze, though I may have executed a double or triple squeeze and not even knew it!
Both involve a ton of deductive reasoning. In bridge, if there are 2 hearts left, and one of them is the Queen, it's doubtful that the odds of one defender having the Queen versus the other is 50/50. If you pay attention to their leads and their conventions (like maybe opening lead of 4th best from longest and strongest suit against No Trump), and with the carding signals from the previous tricks, you might be able to nail with certainty that East has the Queen of hearts rather than West, even though neither East nor West has shown out in Hearts, and trapping that Queen might be necessary to make your Four Spades contract, just like how Yusupov had a game in 1983 where the only winning move was a Queen Sacrifice on move 18 (18.Qxh5).
You can't say one is better or worse than the other.ponz111
duplicate bridge is a great game which I have played for 67 years.
I have noticed many top chess players also play bridge.
There is luck in both chess and bridge but more luck in bridge. To give one example: In a duplicate bridge tournament my partner and I were winning after 26 boards. Then we were paired against a rather poor mom and pop team. They bid the hand very wrong and ended up in 2 Spades. They should have been in 4 Spades [game] which with normal distrubtion would have about a 77% chance to make. The other pairs were in 4 Spades It just so happened that everything was wrong on the hand. The finesses did not work and spades split 5-zero.
Mom and Pop were down 1 against us but this was a complete top for them and a bottom board for us and we ended up tied for 2nd place.
It is not really correct to say you need to look up 3 other players. If you play bridge on the internet there are many players.
Also, there is a thing called an "Individual" where I do best. In an "Individual" you do not have a regular partner. Your partner changes each hand. A pair does not win an individual, a individual wins an individual. About 4 years ago I won an "Individual" of 1060 players.
Except for bullet and blitz chess--bridge is the faster game. You are required to make about 25+ decisions for an individual hand. [about 4 minutes for the hand]
