There are many bridge sayings, for example "The five level belongs to the opponents". But each case is unique.
I made my choice before reading the analysis, I chose pass, but of course the title of the post might have influenced me. But I think I really would pass. Lho is placing a bet, maybe he collects, maybe not.
As for you pard, I am pretty sure I would not double 5
with his hand. I would perhaps consider 5
, but probably not that either. I would probably pass. I would not expect my
A to cash so in general I would not expect my hand to be worth much on defense.
I think that the main reason I, with your partner's hand, would not double is that maybe 5
is right and while I don't want to discourage him from bidding if he should wish to. I'm not saying my (your partner's) pass is forcing, imo it isn't, but passing leaves a 5
bid open for him while doubling 5
really discourages it.
I don't regard the choices here as clear, not at all, they seldom are on an auction like this. But I think that if I am playing with my clone then Lho is playing 5
undoubled.
