Bot Programming Perhaps Last Time
I have little personal experience playing with the BBO bots, but a significant source of error seems to be taking too literally the 'announced' point ranges. The 4 bid showed a maximum of 10 HCP, declarer had already shown up with 11, so west 'had' to have the spade ...
Raising an invitational bid
In some sequences, where X (or XX) is a legal call, you can show both ‘good’ and ‘competitive’ raises via transfer bids that begin with X. In your example (1) X (P) 1; (2) ??, transfers begin with X = diamonds, then 2 = hearts, 2 = your good ...
take-out doubles??
Right. When overcaller has a weak notrump, the hand belongs as much to his side as the opening side, but opener got licks in first for his side. Overcaller takes on a little more risk, but you find all kinds of fits you wouldn't otherwise. What's more, you ...
take-out doubles??
As a matchpoint tactic, try playing a 1NT overcall as weak. You need escape routines and some kind of scramble Stayman, but the overcall is a real nuisance to the opps. Once in awhile you get nailed, but hey that's one bottom. You'll also have to somehow manage ...

Bot Programmer Definitely Mixed a Variety of Substances
I think your theory is a good one. Back in the day I used to program and market a bridge program, and one of the problem areas was valuing a hand especially in competitive auctions, when 'shape' can be at least as important as HCP. Here for example the 4 ...

I notice I'm getting generally 'better' results if instead of "" the site is "" or "". No clue why that would be. BTW as of 10:00 AM Dec 25 Toronto time, this 'article' is not yet appearing in the search results for ...
Expectations. (Club game.)
30% looks bang-on. I wrote a little program. The 14 'pairs' on a Tuesday evening at Toronto Bridge Club, have lifetime winning percentages of 38%, 40%, 42% etc, increasing to 64% in increments of 2% (totally made-up numbers). That 'field' averages 51%, overall slightly stronger than average. They 'play' each ...

Hawaii NABC Report & ACBL Issues of the day
Jonathan thanks for the excellent report. An observation re: sources of income. Excuse me in advance if my arithmetic is flawed. Also I round a lot. It struck me that total league membership is approximately the same number (at 160K) as total national tournament entries (annually, approximately 35K tables --- 2018 ...
