Ulti and Four Aces are worth an extra point (2 in Hearts) besides their standard value if they were not combined with any other bids as they implicitly get combined with a Simple. Therefore, the soloist should attempt to complete an extra objective in this case: to score more than the defending team. However, since the constituent bets are handled independently, failing to complete the Simple does not cause the soloist to lose the bet but his winnings will be reduced by the value of a Simple. The Simple component, like any component in any bid can be doubled separately.
