You are playing in a MP club event with a beginner. Partner knows the rules of the game and little else. Your LHO is an experienced international player and your RHO is a slightly more advanced player than your partner.
At Game All, you open 1♠ (you do not need to know what your hand is). The auction proceeds round the table (2♦)-2♠-(3♦)-4♠-(5♦)-5♠-end.
Dummy displays ♠QJ10x in a 4=3=3=3 shape - AK in one rounded suit, Ace in the other. Slam is desirable but needs a modicum of care and +680 turns out to be worth 95%.
At the end of the hand, Partner asks "Was I right to bid 5♠?"
