(I forgot vulnerability)
You play IMPS and after dealer opens 2D Multi (weak 2 in a major or strong 4441) and his pard bids 2H (weak response or decent hand with mild tolerance for ♠but not ♥), we bid 3 diamonds.
When the bidding comes back to us the questions are:
1) is double takeout at the level of 3 spades. This is undiscussed, and the t/o of 3 Spades is quite high level and there may be equal arguments for using it as penalty or takeout.
So - besides the obvious "you can play whatever you want/like with agreements" I'd like to know what to expect in this situation if I have no agreements;
2) if the double is takeout: would you reopen by t/o or by bidding at the 4 level at:
- all vuln
-none vuln
- unfavourable
-favourable
3) if the double is NOT t/o. Would you compete ?
4) what would you do at Matchpoints ?
Thanks !
