First time partnership. Partner is world class.

MPs. All white.

♠T986
♥75
♦J85432
♣6

(2♥)-X-(4♥)-all pass

partner leads ♠A
(youre playing A from AK and UDCA)

dummy is:

♠74
♥863
♦AK6
♣AKT754

Your play.

Part 2:

Spoiler

partner plays sK on trick 2, your play again.

I want a club ruff.
I would play ♠T, discouraging. I'm used to the logic that one discourages to get partner to shift, and not that the situation suddenly becomes a suit preference situation, when we normally show attitude T1.

If partner continues with the king, I will then play my lowest spade on the second round.

Btw, with my regular partner, we play something very cunning (we think ). High even spade would discourage spades and point to clubs - high odd spade would discourage spades and point to diamonds. Given we have adequate length in spades.
This tends to give us a good chance in a lot of situations.

♠T then ♠6.

Assume you played ST then S6 for reasons posted above.

So what did pard lead to trick 3?

Nice playing by the way.

Which sequence says 'I want C-ruff? which says 'kill S-ruff in dummy? verses 'I overruff dummy'? Which says 'nothing to say -partner, make your best guess'?

Off the top of my head, these cases exist. Which others? Then what signals for chosen cases? Which cases left to by guess, by golly?

An analysis of payoffs for 'got this case right' verses 'not these cases' sacrificed. That is frequency with score payoff/ traded.

Or just a 'gut feel' in choosing signals on this hand (these problems)?

Is partner not supposed to switch when I discourage? I'd play a more neutral 8 (for fear that partner will switch as asked and then they'll make 6 for a screamer) and then the 6 for reasons already offered.

At IMPs the ten is right.

'So I was defending this hand with one of those 'World Class' guys on BBO and I held T986 / A5 / J85432 / 6. He led the Ace of Spades and I SCREAMED for a switch (looking at the 6 Clubs on the board with lots of tickets he'd have to figure out what I might be looking for) but he forgot that to give me a ruff he might need an entry later in the hand. So he cashed the King of Spades and the hand was over.'

I imagine partner will cash another ♠ when looking at a ♥ stop and switch immediately when hoping you have the ♥ stop.

Partner would lead K with AKQ of S. So Declarer has the Q of S. I think Qxx and AKQxxx of H is a bit heavy for a non-vul 2H preempt. So im going to play partner for a H trick.

So Im asking for a switch and even if partner dont cash his S king im not afraid that hes going to lose it.
