I play a number of board and card games with varying degrees of skill, but using "algorithms" to avoid the most obvious mistakes. Depending on the game, if you can beat me, you are probably not a beginner, and perhaps a pretty good player.

comment Bidding response to convenient minor bid
I've heard of things like "Bergen raises," where opener bids one of a five card major, and responder raises to four, with five trumps and zero points (law of total tricks). Is that also prohibited, or is it allowed because it is "non-forcing." Is there a ACBL link that shows what is permitted, and what is not?

comment In Axis and Allies, is the Axis “economic victory” condition a valid one?
Interesting. At the beginning, the Axis have larger armies to compensate for lesser industrial capacity. In this version, the Americans have a larger army, "ready to land," (plus the advantage of the last move), to compensate for the lower industrial capacity. Butting barring such temporary advantages, superior "industrial capacity" usually wins in the long run.

comment Bridge: Matchpoints vs IMPs: Different game?
I made the question more objective by asking for "experience" with actual rankings, and wonder if it can be reopened in its current form.

comment In bridge, how would you bid the “worst” 14 point hand?
With 12-13 HCP I would probably "punt" by passing. The meaning of the question was, what do you do when you have a rare hand that falls into the "cracks" between your various conventions? My "convention card" would read, "15-17 point NTs, five card majors, four card diamonds, three card clubs." But I reserve the right to deviate with a hand like the above (for the question, I deliberately constructed one that is on the edge in every way.) But thanks for a good answer.

comment Did a bridge column make errors in discussing a hand?
@Aryabhata: I am by no means an "extraordinary" player, but East's defense is indicated to me by my algorithms. In my group, I am considered "intermediate," (based on results), but with the highest potential, since our bridge teacher considers my algorithms "beyond her." My goal is to develop algorithms or heuristics to make currently "extraordinary" plays accessible to average players.

comment What are good reasons to lead dummy's first bid suit?
I am trying to do original research. E.g. identifying hands in clusters, trying to find which are squeeze prone, which others lend themselves to a long suit game, etc. I've "backtested" this work on a small sample of hands from books, and need to enlarge the sample sizes in e.g. Monte Carlo simulations. As a mathematician, you probably understand what I'm trying to do.

Welcome to the site. An upvote for a good answer.

Forgot about the singleton in dummy's suit, and the ruffing possibility. Good point. As for "breaking up a squeeze on the opening lead," I'm trying to design algorithms to recognize when this is likely to happen. See my reply to my commenter.

comment What are good reasons to lead dummy's first bid suit?
@user6477: No, it's the other way. I'm trying to find out if this isn't a good lead that should be made more often. My theory is that if dummy has 6-8 hcps, (probably one entry in the bid suit, one side entry), you should try to attack those (scarce) entries.

@Jefromi: "The process of building, once you have a direction to go in." I presume that's more objective.

comment How do people build a Magic deck once they have a general starting point?
I have tried to make the question objective by asking how people actually build magic decks, instead of how they "decide."

comment In bridge, how would you bid the “worst” 14 point hand?
OK, a "random" T (e.g. KT of clubs) doesn't do so much but T behind QJ in spades is worth quite a lot, right? I also consider QJTx worth about four points.

comment In bridge, how would you bid the “worst” 14 point hand?
Actually, I put in the T because I thought it would take the hand just "under," not to, 15 (a second T or well-placed 9 would have put it over). But what you do without the T?

comment In bridge, how would you bid the “worst” 14 point hand?
@ji8e: (Mostly) good points. IMHO, the spots could be worth something. I play that T9 is worth a point behind a QJ (essentially you have three "jacks,") but not in say, KT9. Likewise, TWO QJT sequences are worth a little extra. Again, the Ts really upgrade the Js.

@sitnaltax: One club! I had entirely overlooked this option.

comment In Puerto Rico, does it make sense to shift to a corn-based strategy mid-game?
Basically, it seems that a "corn only" strategy doesn't quite work, but a corn "almost only" strategy can work.

@Jefromi: I think that's the question "How do people decide what kind of deck to build?"

@user1873:Fair enough. I have done my best to improve the title-content "match."

comment Do “interaction” effects cause people to buy buildings in tandem in Puerto Rico?
@MonicaCellio: In the answer to this question, boardgames.stackexchange.com/questions/4093/…, the answerer wrote: "The question is not what buildings have good synergy with each other. The question is what buildings have good synergies with your particular strategy." I say "each other" is a very important effect in and of itself. You seem to be more clear-headed than most. I have read that Artificial Intelligence (AI) players are more likely to adopt building strategies than human players, perhaps because they understand this better.

comment Do “interaction” effects cause people to buy buildings in tandem in Puerto Rico?
@MonicaCellio: I'm referring to the back that you score 4 VP for owning building X and 1 VP for owning building Y in isolation, for a total of five; but if you already own building Y, you get five points for building X (this includes a bonus point for building Y) for a total of 6. This is what I call the "interaction effect, which I consider a key part of PR. Apparently few other people take this into account, at least explicitly. I believe it's at the heart of this question boardgames.stackexchange.com/questions/2202/…
