Online training: Please remember to detect the honors beforehand !!!

This deal happened in our weekly online training last Monday. I couldn't concentrate my attention due to the lack of card sense online. Rookie mistake should be mentioned here. Board 13 Vul: Both Dealer: North East    West 1NT      2♣  2♡       4♡ Lead: ♠7 South led ♠7 while North followed ♠J. And I won with the ♠Q. Now what's your plan? ♠7 seemed to be doubleton. Firstly, you couldn't avoid to lose 1♠, 1♢ and 1♣ at least. In other word, you must make a right guess in who had ♡Q. For me, due to the leading, I had supposed South hold long ♡ and he hadn't led trump, so I just played casually, cashing ♡K, then ♡J->♡2->♡5->♡Q... Oops...

Crossing to table with ♣K. And now the distribution was clear. If one A for each, now it was your guess time, n...

Interactive Hand Testing

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 ...
