After our training, a world master taught us tactics and commented upon our games. It is really helpful, and I have corrected many of my mistakes!
In the PDF, first comes the little slam contract. I was South and my partner shut out the East 2 diamond opening bid. However, they managed to find the hearts and made a 4H bid. I was very excited when my partner support my spade. Although we had only 25% chance to fulfill the contract at the first glance, I was sure that I could make it because I had inferred their cards from bidding. Sometimes too competitive could cause even more trouble. ^_^
I was at work during the day, so I only caught up with training in the evening.
