Is there a sound mathematical basis for this?
Analogy is a powerful tool of thought - potent for coming up with ideas, for guessing at lines of reasoning and answers. But trying to reason by analogy is a lazy and unsound substitute for reasoning rigorously. I read David's argument to be reasoning by analogy as follows: 1. There ...
Is there a sound mathematical basis for this?
But Bart, I don't see much similarity between your 3 aces premise (for which you give the right answer) and Craig's question premising KQJ (for which the answer is different). Kit's statement of the premises accords with my reading of Craig's problem, and he argues directly ...
Venice Bridge Tournament. Harris Pairs Withdraw.
Why plural anyway?
Six Card Ending in 3nt
Knowing that the defenders are robots would have helped me to fathom East returning the 7 with 1075 remaining, as I have no recollection of such a play from a human but I have read that the bots' spots are meaningless. But still the 7 is a remarkable play as ...
Vanderbilt Hand 315: 5!D
By the way I'm surprised that both declarers played for 2-2 trumps. From trick 1 RHO has AQxx(x) and is quite unlikely from the overcall to have the A, hence couldn't bid 4 with a balanced hand. A singleton is more likely than ...
Vanderbilt Hand 315: 5!D
Nice line. An alternative, maybe simpler: ruff trick 1 with J, continue K, low to 9. Lead J. East may as well cover; win A, cross to A finishing the trumps. 8, 9, K, then 6,any,5,7 (not that blocking the clubs would matter). Ruff East's ...
Cashing out
I get 64% as the sum of Kieran's cases.
Cashing out
After the A, A, both defenders can see that the J is irrelevant unless West holds AJ or East holds QJ (and hence leads the Q, not small). Therefore the low diamond showing an honor must be showing at least the Q, so if it goes 2,K,A I ...
Trick 4 Play
David's argument states the psychological point most economically, but is it accurate? The voting still shows a large majority shifting a club, and among those of us choosing a spade or heart, I for one confess my spade choice came partly from considerations not available at the table. One ...
Trick 4 Play
Yea. My bad edit. I was toying with up to five clubs possibly including the jack. That became a notational mess so I simplified but not very accurately.
