BOTs need Aud.Grant remedial lessons

[MsPetey]

EVERY bridge book in the world teaches Double then bid BIG HAND. My BOT was a passed hand; RHO BOt opened I doubled; then bid 3Spades, passed hand bot goes to 7 level.

 

Certainly like my money back since it's a rebate tourney I'm playing

 

ALSO EVERY BRIDGE BOOK IN THE WORLD teaches in NT LEAD FROM LONGEST & STRONGES SUIT.

 

What's up with singleton lead by BOTs ! ! ! !

What's up with singleton lead by BOTs ! ! ! !

basically, gib plays based on a double dummy analysis of some random simulated deals (the number of deals are very limited). When gib leads, most likely, it can't simulate enough hands to find the killing leads, because those situations are generally rare events under normal bidding constraints. Therefore, among all the leads, gib would choose the most passive leads based on a double dummy point of view, in which case, stiff honor, singleton, low doubleton, low three(four or more) are all very passive and unlikely to cost a trick based on double dummy.

 

The solution is to override the double dummy simulations and make some leading rules as what human players do instead IMO. Also, once a human player makes a lead, gib should also adjust its simulation constraints and take the lead more seriously, that's the only solution to avoid horrible switches after human players make a killing lead and only find gib partner makes an very low percentage switch to allow the contract to be made. Of course, the above is easier to be said than to be done. Still, the program can be improved a lot if the change can be focused on the leading and first trick play.

 

Another potential huge improvement is a signal system. Of course, it's not easy to implement an attitude or suit preference signal. However, a counting signal is very simple and should be implemented IMO to improve the defense and make the mbt or mb more like normal bridge.
