My analysis: PASS! i. Max points between E-W ≈ 25, ii. Opps are NOT in game, iii. At 3♥, N-S may make +120 or even +150, neither of which makes it worth a sacrifice when vulnerable, iv. E-W might score +140 at 3♠, , but more likely -200 or worse (3♠-2 or 3♠X-1; losing 1 ♣(perhaps to a ruff), 1 ♦, likely 2 ♥, and likely at least 1♠)? v. Why risk it when partner still has another call? With a strong opener, East has numerous options, including Pass!
