Also, Michaels cuebid variants exist that remove any ambiguity on what is the second suit. An example is the "hi-hi cuebid" that over opponent's opening invariably shows the highest unbid suits. Together with the unusual notrump convention to indicate the lowest of the two unbid suits, this hi-hi cuebid allows two out of the three possible two suiters in the unbid suits to be specified in one single bid. A drawback of this method is that the hi-hi cuebid does not cater for two-suiters in the highest and lowest unbid suits.
