Asian Game_ Supermixed Final_ China vs Hongkong, China: A disaster for natural system

This deal happened in the first segment of Asian Games Finals, China vs Hong Kong, China.

I'm a big fan of Wang wenfei, to be exact, I hope my team could win them one day. 5 battles, 4 lose, 1 tie. So this time I kibitzed by South only, imagining if I was her opponent, what would I do.

Board 2
Dealer: East
Vul: N-S
South

♠ JT8
♡ AKQ862
♢ 3
♣ 953
1. East open 1NT(15-17, bal)
2. East open 1♣(Precision)

Will you overcall?
Wang used Precision System. Whatever Natural system or Precision, I thought I would not bid at the first round, especially Natural system. I just hold 10 points and vul is harmful. It is quite hard for me to go game or rob a part contract. The optimal situation is opponent's reaching 3NT and I could win 6 tricks directly. If I have one more A, I would bid for sure. If opponent use Precision System, you may have chance to bid on the second round. Or they might reach 3NT and the I could laugh in beard.

The full deal
Board 2
Dealer: East
Vul: N-S
Without overcall, E-W will be easy to reach 3NT(1NT-3NT) under Natural system. For Precision, E-W might reach 5♢. So it will be a natural disaster for Natural system.
However in both tables, China and Hong Kong, China overcall together. Normally, both tables will find 5♢, but Hong Kong, China who use Natural system still reach 3NT. Quite unimaginable.

The processes are as followings... In terms of results, it is still a disaster for Natural system, but not a natural disaster, it's an artificial disaster. Hahaha...

Online training: An unexpected but reasonable ducking

HAHAHA, after one month off bridge, I'm back!!! This deal happened in our weekly online training, Nov 5th, 2018. First of all, I have to admit my mistake. Hahaha, to be honest, the training was quite boring. After 12 boards, the scores were still 2:2. Although I knew X was not allowed and I would be fined if 3♣X was brought home, I still couldn't help to doing that. Board 13 Dealer: North Vul: Both North    East    South    West  Pass     Pass      1♢         2♢*   2♡*      2♠       Pass       Pass   3♣         X         AP 2♢: Michael 2♡: ♣ suit, better than 3♣ Lead: ♡3 (if hasn't raised, count has a priority. That is to say, xxx lead the smallest card) Table followed ♡9. Normally, you would play ♡Q causally. Would it be correct in this case? Leading analysis: Eas...

Interactive Hand Testing

Fu Bo shared this deal with me. This deal happened in the open pair qualify of the 15th Would Bridge Series. She asked me could you find out the defense even if you saw 4 hands. Interactive hand analysis was interesting and played an important role in improving bridge technique. Although double-dummy analysis always stood on a God view, it was essential in a post-mortem analysis. This was first time to show a interactive hand analysis here. I'd appreciate if you could share any interesting double-dummy with me. How to defend 4♠? In this case, defenders should prevent declarer from ruffing ♣ or from winning 3♢. How to cut the connection between table and hand became a serious problem. Timing and speed were the crucial point. 1. Leading ♣     A slow step, losing an upper hand. Declarer could win with the ♣A and sent out small ♣. Even if the defender shift to trump, the declarer was a step ahead. (a) Returning small trump, won by North, ruffing a small ♣ and finessing ...
