Something new.... Henri and the bots

Had a fun time on BBO today. First, I played 24 hands with Henri Schwetzer "ritong" on BBO, who is the inventor of Riton 2♣ that I have happily added to my bidding system. In 24 hands, not one Riton 2C hand came up however. Still, some great bridge. We ended up ahead by over 30 imps.

Then I found that Fred had made version 4.3.3 beta available for BBO. This version brings in bots.. specifically, GIB. It is not clear how much using GIB as a partner or an opponent in the future will cost (hopefully not much), but for now playing with bots are free. Bots filling in for a board or two and in tourneys will be a big help. I downloaded the software and played five hands to see what how the bots played (three bots and me). Here is my test.

One of two finesses and slam should 
make. Assume spade hook wins, 
3S, 1S ruff, 4C, 3H, 1D = 12. 

Unlukcy for bots, and I pick 
up nearly 10 imps

This hand shows the bots clearly 
play five card major as the bot 
wouldn't let me out of hearts 
once I opened hi 1H. Playing 
heart NENE. The bots seem to do 
this a lot as I kibitzed some 
at Walddk's table.
