To state it as friendly as possible: 3♥ is a safe contract. This is one contract that is not going to be defeated... Critical spirits may however remark that 6♥, bar an unlikely ruff, is cold.
East: 'I think you shouldn't have passed 3♥, it's forcing.'
West: 'I thought it was invitational.'
Who is right, who is wrong?
