Some boards will favor a certain strategy and you should go for it no matter what: happily paying $6 for Minion and $4 for Lighthouse, while other boards are not that clear cut: always hitting $5 and going for an engine with Bazaar or always hitting $6 and happily buy Golds and go for a Big Money strategy.

So here's the challenge: create a bot that plays an engine strategy if it draws in a certain way, but goes for Big Money if it draws different. This bot should convincingly beat the optimized bots that go for the same strategy however they draw their money (so also provide the engine bot and money bot).

(engine strategies will have some kind of Village in their end deck while a money strategy shouldn't)

This challenge is cool enough that I feel like it shouldn't keep languishing, so here's a (probably not especially good) solution:

This bot plays FG/Mint on a 5/2 split, or opens Familiar, then transitions into a Fishing Village/Smithy engine if it gets a 4/3 split.  With both bots on a random split, it beats FG/Mint 70-27 (not surprisingly, since FG/Mint is terrible on 4/3), and beats my Familiar/Fishing Village/Smithy bot 62-34.  It also crushes BMU 86-11, and takes out the built-in Familiar bot 78-19 (it loses 26-71 against the "lucky 3rd turn" variant, but I don't think that's really a fair comparison).

For reference, here are the two bots I'm comparing it against (which are just the two halves of the bot above, without the conditional play):

</player>

Both of these bots beat BMU (even FG/Mint on a 4/3 split edges it out 48-45...this just in, Fool's Gold is pretty good).  They're also both competitive against the simulator's built-in Familiar bot (the engine beats it 60-37 on random split; FG/Mint needs a 5/2 split to win, but crushes through 92-6 if it gets it).

(Attached are two sample games, one of it playing the engine, one playing with FG.)

Who's next?

[Geronimoo]

The goal of this was actually to prove that changing your strategy mid game is viable if you draw your money in a certain way. Very often opening $5/$2 against $4/$3 will lead to diverging strategies anyway.

I'm thinking more along the lines of: Open Silver/Silver, then get a Wharf, then diverge into Bazaar/Wharf if you draw lots of $5 or Big Money Wharf with lots of $6 draws (not saying this is a solution to the challenge)

So, A_S00, thanks for the effort, but not really what I was looking for...

[A_S00]

That is harder (which is why I was lazy and went for the 5/2 split case )...I'll see if I can come up with a good case for what you're actually going for.

[Geronimoo]

Opening $5/$2, this bot goes for an Envoy/Fishing Village engine by default, BUT if it gets a Gold on turn 3 it goes for a pure money strategy. It easily beats the pure money bot and beats the pure engine bot by 2% (make sure both bots open $5/$2):
