Hi, I think Jerry's hit the nail on the head. He knows what he needs to work but can't do it at the table because he has opponents waiting for him to play a card. Unless he can train his brain to automatically ask the right questions progress is going to very slow. A computer is an obvious tool as it doesn't get impatient. I used and still use GIB for exactly that purpose. Here's the drill....in defense as well as declarer play. 1.) At the opening lead, stop and write down what you know from the bidding and the lead. 2.) As every subsequent trick is played write down what additional information you have. Try to work out the most likely distribution and high card locations. The key time is when you are fairly sure of 2 suits. This often happens very early in the hand, maybe trick 3 or 4. Work out the combinations left in the other 2.....there won't be that many. 3.) When you think you have the full distribution write it down. After a while stop writing it down. I play with a constant conversation going in my head. There's only one way to make it automatic and that's repetition. You know what the questions are: who has the AH, are diamonds 3-2 or 4-1. Can I find out for free.....
