I open 1
♠. I dont like opening 1
♥ for the following reasons:
1. If I open 1
♥ I will be very happy with 2
♥ response, but I am not very likely to hear it.
On the other hand 1
♥/1
♠-1NT is a likely auction.
1
♠-1NT
2
♥-Pass
I am not overfilled with joy, but 1
♥-1NT-2
♥ to me is an inconceivable auction on that hand.
1
♠-1NT
2
♥-2
♠
3
♥-Pass/3M/4M - yes I am happy.
I dont consider 1
♥-1
♠ auction because if partner has 4 spades I am absolutely fine with opening 1
♠.
2. I am not just unhappy, I am extremely miserable if opponents interfere and I have no way of mentioning my
♠. Consider:
1
♥-2NT-P or X-3
♣ ? (or any equivalent where partner passed and its back to you at the 3m or higher level).
If I open spades bidding 3
♥ is not a problem.
3. I am very happy to bid
1
♠-P-2m-P
2
♥-P-2NT-P
3
♥-P-3NT-P
4
♥
I do play 1h-2m-2s as showing extra, but 6:5 definitely qualifies as extra, so on this auction it would get us to the same spot, only partner would have to guess if I have a K more or not
If I open 1
♠ and rebid 2
♥, this would not be an issue.
