G'day, Becki.
Thanks for the reply (and for the kind words). I'm not the strongest of analysers necessarily either, it's taken me a while of playing this game to figure out all that stuff I told you.
Yeah, playing pairs of cards for stones (and as early as possible, before your opponent gets the chance to) is usually the better play, particularly as it lets you draw two new cards instead of just one. These could be one or both previous discards (to improve your paths or possibly even claim another pair) or from the draw pile to increase your chances of getting more pairs of cards for even more stones. Avoid as much as possible, particularly at least earlier on, playing on your paths numbers for which stones have not yet been claimed and especially avoid discarding them (which will not only hinder your chances of stones, but increase your opponent's chances of claiming them).
Yeah, there does have to be a bit of risk involved when you don't have the greatest of hands, but not as much as there is in Lost Cities. Playing the grey cards on the grey stones for one point each is often the best option you may have (but generally, the longer you can try to hold onto them for the chance of increasing your path lengths to those crucial bonus-point lengths, the better it may turn out, as long as you're not otherwise gifting your opponent points through discards (s)he'd want).
Starting a path even if it doesn't make it to four cards can actually sometimes be an okay choice, because, even if you do end up with a small hit of negative points, doing that can buy you a bit of time to draw more cards which, if you are lucky enough to draw the right cards, may mean you get to play more 'in between' cards on other paths, making those longer, and potentially making up some of (or all of, or even more than) the difference with extra points on those paths (all the while helping you to avoid gifting your opponent points or, even worse, swing points).
If you click on my name to get to my forum profile, there's an Add to Buddy List option on the left. Given you asked, I've taken the liberty of adding to you to mine, which should make it even easier for you to do the same. If you've changed your mind though, that's okay, I won't be offended, don't worry.
Thanks again and have a great weekend,
Stu.
