The hand below is given to 26 humans playing against robots to bid and play.
The call comes round to you.
What do you do? Why?
What is the score that achieves closest to 50% for the group playing it?
What method do you use to evaluate your hand?
This comes from yesterdays Daylong number 1 Board 5.

1. I'd open 1 as did Pilowsky.
2. Avoiding notrump openings with a singleton major, in case partner transfers to it; but I guessed that many would open 1NT.
3. Given 10 attempts, I'd still fail to guess the average score.
4. According to the winning trick count (WTC), this hand has 5.5+ winners.
( singleton = 2 + AK = 2.5 + K = 1 + bonus singleton K = + value).

#1 & 2 - I open 1, because I have no interest in partner leading a Club, and because I can rebid 2 and show my 9 cards in the minors. Mind you, I would rather have 5 diamonds and 4 clubs, but KJxx is better than xxxxx if we don't know what partner's hand is.
#3 - I guessed -150 (N-S), and then looked at the spoiler. Yikes!
#4 - A modified Work count, more in line with the Four Aces evaluation (essentially 4.5/3.0/1.75/0.75)

Open 1. partner has passed so game is longshot. can always pass partner's bid. what suit do you want partner to lead or ? if opps do not bid and partner bid 1 is 1NT rebid bid with K bad. no! as for garbage suit save for poker game.

I would expect to play in 1 or 1 (unless opps decide to play 4)

1-P-P-X-P-P-XX/1 and onwards
