Uday, the key is for there to be different decisions, inferences, and judgements available. A different NT range from your counterparts is perfect. This creates a lot of different situations and inferences which is exactly what you want. Different decisions on preempting or overcalling are also very good. Swings at the highest levels can be created from very small things like this. There is no need at all to overdo it. I think not bidding close games is a huge mistake against anyone. This is the bread and butter of the top teams, and the situations arise so often in a match that they WILL beat you on these boards if you don't bid your close games. Rather, I think it is better to bid or defend these games after a slightly different auction where different inferences are available. Both declarers may then make the "right" play and one may go down while the other makes. Slam swings can often swing the match. I do think trying to do the opposite of the other team on slams in the 45-55 % range is a good policy. There will probably be just 1 or 2 of these in a match, and if you are on the winning end of both of them you will become the favorites. Don't overrate how outclassed you are, the top players are human too and I happen to know you are quite a good player yourself. As for the client factor, sit your most active pair against him. I always try and put a lot of pressure on the client in both the bidding and play to exploit his weakness. Definitely bid em up against the client, and make him use his judgement as much as posible.
