Just realised that this section is more suitable for my posts
Dealer passed, and for once partner did not open in you void suit.
He opened 1♠.
East come in with 2♥ and it's your bid.
On the table I considered 2 possible actions :
1)Bid some number of ♣s.
For this I felt like 5♣s seems like a good idea as we play this as preemptive style, denying as much as 2 defensive tricks. With 2 or more we start with 3♣s.
But after some reflection this seems like a bad idea as 3NT can easily be our best spot.
So probably 3♣s is better?
2)Raise ♠s.
How how to raise? How good is my hand in support of ♠s?
Our definition of a limit raise is 3 cover tricks... is this correct? And if it is, does it mean that it's ok to cuebid 3♥? The problem is we also define a cue in such situation as "our hand" (is this a wrong idea?) so we might have to double them later if the auction gets too high.
