Don't worry, I'm used to this sort of thing in other places - but other BBO players may not take it well.
Let me illustrate another point where I think the use of an UNDO call was questionable. This was
not at the table which I referred to in the OP, but on a different occasion several weeks ago.
I passed as dealer, and my partner opened 1
♣ or 1
♦ - I forget which. RHO overcalled 1
♠ and I passed, and so did LHO. Then RHO asked for an UNDO, and without thinking too much about it, both I and my partner accepted. So RHO retracted his 1
♠ and doubled instead.
This seemed a bit irregular to me, since it now transpired that RHO had disclosed two lots of information about their hand: strength and spades, in a somewhat unauthorised manner.
Anyway, this now gave me room to bid 1
♥ so I did so. This was passed around to RHO who now bid his spades at the second attempt. I passed but my partner took us into 2
♥, the final contract. It was not a good contract and I went down.
I felt that, on that occasion at least, my opponents had not taken advantage of the retraction and RHO had shown his spades legally. And my poor result was my fault really. So no point in making a fuss. But since then, I've been wondering about the whole process of UNDOs. I shall go on being wary of them.
Anyway, enough said.
