Imagine. This was discovered way back in 2009 and we're just finding out about it now. You can thank me later. Meantime, let's get to work.
We're going to look at responding to Pard's overcall. Whether a NEW suit by overcaller's Pard (the advancer) is forcing or not is a bone of contention between many players. Here is an agreement that may well work for you. A new suit by advancer is passable at the one-level, but if possible should encourage you to try to find another bid. At the two-level, it's forcing--after all, Pard's got at least an intermediate hand. Talk this over.
The only absolutely forcing bid by advancer is a cuebid of the opponent's suit which promises a FIT and 10-plus points. So, for our purposes, a new suit is invitational but passable (at the one-level), a cuebid is not.
So let's see what we'd do in these instances of Pard's overcall.
