In money bridge, against 4D x
You hold SAKxx HQTxx Dx CAxxx and lead SK,
dummy: J9xx Axxx Kx Kxx,
your gib plays 4 from 48 and you decided that you need to find partner's HK and switched H. Declarer won by HK in hand, played three rounds of D, a low S coming, so you naturally play low, just in case partner holds SQx or Qxx, no, dummy won by SJ, played HA, pitched declarer's SQ and later took the club finesse for an overtrick. This is the hand clearly showing that it is simply unwise to believe gib plays any sort of signals. Against any human players, the defense would be very easy and straightforward, SK, S8, then SA, S4, then, CA and spade ruff for down one.
I think bbo should at least modify the code and allow gib to give a simple reliable counting signal on the first trick, which is really easy. Still, after so many years, no any modifications have been made for such a simple improvement.
