“Detecting Cheating in Bridge” by Nic Hammond. Preliminary thoughts
This might be an algorithm for ‘cheating on lead’. In the double-dummy world, about 1/3 of the time a (normal) lead from any suit is best (all suits tied), and about 1/3 of the time there is only one suit that is best (I never find that suit ...
Am I just wrong?
I just used DM Pro on 25K notrump contracts ... balanced 14 opposite balanced 10. After dealing, the option to proceed with Deep Finesse tells me 3NT makes 8945 times, whereas proceeding with DDS tells me 3NT makes 8945 times. Other comparisons (making xNT) are likewise identical. The DDS calculations are ...
Am I just wrong?
DM Pro uses two different DD engines. At the end of the 'dealing' phase, if you continue with 'DF Analysis', DM Pro uses Deep Finesse. If you continue with 'Continue', DM Pro uses Bo Haglund's DDS (which I find is considerably faster). Outputs are different.
BW Censorship
A couple of years ago I surveyed double dummy leads against a ‘blind’ 3NT contract. I was impressed with how many ‘ties’ there are for ‘best lead’. Only 32% of the time, the best lead was from one suit. Some 12% of the time, two suits shared the honor. About ...
Explain this double
Good spade raise. 3 is minimum raise.
Script for colored suit symbols in Google Docs
Ahhh that works nicely, thanks. Years ago I modded some fonts with FontMaker, so that '[' became , and so on. Doesn't solve the colour issue though.

Bot Forum: Are Bots too Human?
It's possible for Programmer to build an ‘unlikely to have’ table that the proxy deals would ‘consider’ (can’t be tough, I’ve done it). In your example, from RHO’s perspective, LHO would be considered ‘unlikely’ to have the King, having not beaten the Jack. There are all ...
Bot Forum: Are Bots too Human?
Thanks. So when leader’s partner is ‘determining’ best play when he is on lead, the proxy deals will skew to xxx(x), with poor prospects, so he looks to switch. High-spot leads from weakness would help a lot, but Programmer would have to intercede.
