After the first forcing pass, I didn't have much interest in playing a ♠ contract and I was happy to defend. Partner however showed a SI with a good ♠ suit.
I had a good hand, I had a ♠ honour, so I decided to bid on. Not sure what my partner is looking for and suggesting an alternative trump suit I just bid my good ♣s. Do you agree with this?
Now LHO bid 5♦ (having a laugh) and partner made another forcing pass! Since I didn't have a ♦ control it looked to me like slam was far away, so I doubled again. Do you agree?
Now partner bid 5♠, again showing slam interest. What is he showing and what is his problem (if he has any)? What would you do now?
