Sandwich Notrump - When one opponent opens, partner passes,
and other opponent bids a second suit, an intervening Notrump call
"sandwiched" between the two opponents conventionally show a weak two-suited
hand in the remaining suits. Thus, the Sandwich Notrump functions
similar to the Unusual Notrump.
Since the opponents will usually have the
balance of power, the Sandwich Notrump caller seeks a great trump suit fit
in which to compete. This overcaller often has few points, instead
hoping the fit and vulnerability will compensate in competitive bidding.
Ideally, the Sandwich Notrump intervention will either push the opponents'
into an uncomfortable contract or lead to a profitable sacrifice.
