You "know" either from previous experience or from convention card (if you can find one) that opps play transfers over 1N.
North doesn't, however, alert (or announce - delete as appropriate for your regulations) the 2♦ bid as a transfer.
You are next to bid and wish to double the transfer bid.
What do you do next?
- Do you query the bid and then double after it is confirmed this is a transfer?
- Do you pass, and seethe when they play in 2♥ and it turns out your side could have made 3♦?
- Do you double anyway?
This situation (non alerting/announcing of transfers) happens more often than it should, and I never know how best to handle it.
Advice welcome.
I'm always worried with option 1 is that maybe the opps aren't playing transfers (there is no convention card, no announcement, and maybe you have misremembered what they played before, or maybe they've stopped playing transfers) and then 2♦ turns out to be natural after all then asking and not bidding is bad because it implies you have Diamonds too.
You are potentially in a "damned if you do, damned if you don't" situation if you ask/don't ask.
How would you recommend such situations should be handled?
