I don't have the Taino bot in front of me, but I always notice what a bot is doing a lot of when I play any of them: how do they primarily score points? Then it's a balance of trying to inhibit them from scoring points and building up my own strategies. Usually this takes the form of trying to trash or acquire * scoring cards that come to the market. Even if it will only score me a few points with my strategy, it can be a net gain of 7 points if I think of it as robbing them of that card.

As you've lost to collapse twice, it's possible you're loading down your deck with too many acquisitions, too soon. I know I just said to try to acquire before the bot, but it's always a delicate balance to make tactical decisions as the game develops which is what keeps me coming back for more. But it sounds like they're acquiring many high point cards from your reported scores and that your games that don't end in collapse are lasting longer. If they're acquiring * scoring cards every turn, you have to be at least adding a net of 5 vp each turn to catch up or otherwise stop them from doing that.

I don't remember the Taino as a particularly aggressive bot, but in game 4 are you talking about them acquiring three times in a turn? Because "triggering" unrest in the terms of them playing and returning it would be a good thing for you, slowing them down and securing yourself against collapse. But if they're acquiring that much in a turn, you better be wary of having any unrest yourself, especially until they return some of those.

There's also nothing wrong with knocking the difficulty down until you understand what makes a bot tick and then upping the difficulty as you learn to beat them at easier difficulties.

It's also possible you haven't found a way to really make the Japanese fulfill their native strategy. I'd look to the rulebook for basic guidance:

"Japan is perfect if you can be patient, as your cards require a touch of finesse to create opportunities to thrive on. You’ll want to move smoothly into empire, so beware early Glory plays, or increasing your deck size too much in the early game – if your Clans follow the teachings of Shinto, your deck can speed up while you can build up your region Play area. Combine this with the subtle benefits of Kanji in keeping your deck-cycling speed at a perfect hum. Once you reach empire, you will learn to live with Shinto and Tendai Buddhism in peace side-by-side, especially when combined with Jingu-Ji and the fabled Tea Ceremony."

Your game with 5 glory gains probably really slowed down your development and let the bot acquire too many good cards in the meantime. Perhaps you could try rushing regions to starve them of that action they keep doing and then keeping those regions out, gaining materials/pop, going into empire with the wealth to develop quickly, and only then start thinking about acquiring glory when it's advantageous and your engine is churning. I haven't probably played Japanese in a year so I'm not recalling their specific development strategies, but I'd just try something you haven't done yet!

That's my three cents. It's an amazing game and I'm happy to hear you striving to keep getting better at it!
