I would expect partner to bid again in the pass-out seat. It is seriously bad bridge to allow opponents to play 2♥ when we have a known spade fit and both sides have 20 points or so Had I opened 1♠, partner should be happy to bid 2♠, so why pass now when I have shown opening values, heart shortage and a spade suit? Rule #1 - Trust your partner Tony Because you might not have a spade fit. I assume you are objecting to the possibility of playing a 3-4 ♠ fit (apparently my definition not yours) but guess what if you bid 2♠ because you have 4 with a minimal hand you still may end up playing a 4-3♠ fit. IMO if you bid 2♠ with no extra values you are bidding the same values twice.
