For better or worse, we play 1♦-1♠-2♦-2♥ promising 5+♠, so I guess 1♦-1♠-2♦-2♥ is out of the question with our methods. Yeah not many people play what I suggested. Playing 1♦-1♠-2♦-2♥ as art. GF, how do you show weak 5♠-4♥ hands? With what type of hands do you think the 2♥ art. game force gains? loses? I play 1♦-2♠ is a hand that would bid 1♦-1♠-2♦-2♥ in standard methods and that 1♦-2♥ is a hand that would like to do that but is too weak. The pluses are: (1) 1♦-1♠-2♦-2♥ can be used as an artificial game force (2) we can show a weak hand with the majors. We can also do that in standard if partner is sporting enough to rebid 1NT, but we're out of luck if partner rebids 2m. The minuses are: (1) these auctions require really good hand valuation skills for both opener and responder (this is not as easy as it seems) (2) 1d-2M can no longer be used as strong, weak, 3-way, etc. which are all helpful as well (3) good agreements after 1d-2M are required to ensure that you don't have system losses
