If you misbid or misplay or misdefend a hand or two in a daylong, then your mentality should be that you will do better next time. Improving your bridge is a slow, ongoing process.

In my BBO profile it says Board completion rate: Unknown Does anyone know how a player's board completion rate is determined?

In a playeer's BBO profile a compatibility rating is shown. For example, mine is five stars, which sounds good, but how is that determined?

Based on the earlier comments, this may be wrong, but I've had the impression that if you play early in the day, then BBO may not have enough of a sample to provide a valid provisional result. If that happens you have to wait until the next day to see your result.

When you finish a "Start a Bridge 4 Game" (free on BBO), no percentage score is shown. At least, I've never seen one. You only receive a ranking, which could be anywhere from #1 to #52,000, or something like that.

BBO has to balance the comparison feature of MP scoring with the need to minimize cheating. Unfortunately, there are a small number of players who receive gratification from cheating in order to win or place high in a tournament. BBO has to take that into account in setting the paramenters for daylong (and other) tournaments.

Not sure what the problem is. The daylong hands are biddable and playable. Make sure you look at brief bidding descriptions before you bid to determine what your robot partner's bid (probably) means and how your robot partner will interpret the bids you make. As an aside, it is hard to win a daylong tournament. In addition, my perception is that technically the daylongs are tougher than the typical in person local duplicate event. I'm a fan of the daylongs. They have helped me learn to play better.

Never thought about 10 as an issue, so changing 10 to T would be a solution to a non-existent problem.

West's most likely distribution seems to be 1-8-2-2, and that could include a singleton spade honor. I'm guessing East holds the club ace. So cash the spade ace, then play three rounds of diamonds, ruffing in dummy, then lead a spade from dummy, hoping to lose one spade, one heart, and one club.

Playing in hearts you could lose control and go for a big number, so three diamonds.

Diamond ace, then low toward the jack. If necessary, take the heart finesse later.

Pass, by elimination. The other "options" (3C, double, 3H) are too flawed, so just pass.

Try to open 1NT as often as possible, so 1NT.

Three diamonds. Nothing else makes sense.

East is on the top end of a two spade bid, but West has enough to bid again.
