So the most interesting part begins when Graves is on lead at trick 4 after winning with the Ace of Hearts - see if you can come up with what he played to set the contract.
(Accurate play is still needed after this trick as well).
So my question is what his thought process must have been here to come up with the only correct choice. Anyone care to speculate?
Alan is a friend of mine, and a former teammate and partner and a great player, but I don't see this as especially difficult for an expert.
One can look at it either as there being positive reasons to work out a spade shift, or negative reasons making any other choice less attractive than the spade.
Positive reasons:
Declarer attacked a 5-1 fit, missing A10xxxxx in hearts, rather than spades
Declarer chose to try for game in notrump, never raising spades
In addition, Alan can reasonably infer that declarer probably has only 2 clubs, or (more accurately) that the defence cannot set the hand if declarer has Hx in spades and 3 clubs, hence 2=5=3=3 shape...not to mention the 2 points above, both of which reduce the likelihood of these holdings.
Finally, if one is shifting to spades, the Q is the obvious card for several reasons, of which the best is catering to a stiff J in declarer.
The negative reasons:
a heart....one need look no further than the fact that it is virtually never right to play on the suit declarer is establishing unless one has a very unpleasant surprise in stock for declarer, which we definitely don't have
a diamond: declarer is marked with some length, at least 3 plus, and some strength in diamonds and probably lacks dummy entries to play them to best effect, unless we help him.
a club: what's the point? we don't have a shred of an entry now the heart A is gone.
I don't claim that any of the above meshes precisely with Alan's thinking. I always enjoyed talking bridge with Alan, because he saw into the game differently than I did. We'd have some really enjoyable (well, I enjoyed them and I think he did too) discussions about the relative merits, for example, of up the line bidding as opposed to walsh....he was strongly up the line and I was passionately walsh.
I learned a lot about the game from Alan and am really delighted that he is playing so well these days.
