It is extremely frustrating when members leave in the middle of the play of a hand. Not only is it very unfair for the person who takes over the chair, especially a few tricks into a hand, but for those who do not leave. I recently was dummy on a very interesting slam bid hand that had a high probability of making when the declarer felt overwhelmed and left around trick 5. It took several minutes for a replacement to sit in who was willing to stay and play it out. Also one of the defender chairs changed 4 or 5 times by the ecnd of the hand. This severely hampers the enjoyment! It is not just the occasional board, but a frequent occurrence. Almost everytime somebody makes a bad bid, they just leave instead of completing the hand. I would like to see a system put in place where a member who leaves during the play of the hand more than a couple of times a month receives a warning from the system that if they do it again their membership will be suspended for a month. Also for repeat offenders their membership should be terminated. It is rude and, like I said before, it detracts from enjoyment of the game for the rest of us.
