Aww, now you've told em all the tips

and it's going to be harder to win

but since we're telling people some strategies here's one that I use when trying to decide how many tricks I think I'll win.
Obviously Aces and Kings will normally get you a hand apiece, Queens will normally get you one unless your opponents only have a couple of cards to that suit. If you only have < 3 of any suit and some spades to play, you can normally win a hand that way.
Example hand for playing cutthroat spades, 17 cards per hand:
A,K,Q,7,5,2 Hearts - A,K,Q
K,J,10 Clubs - K
Q,10, Diamonds - Q
Q,J,10,7,6,5 Spades -Q,J
With that hand I would bid to win 7 tricks, as 2 suits are 3 or less cards I would hope to grab the trick using my lower spades. A word of warning, if you've a handful of Spades, 7+ , presume you're going to win a lot of tricks.
If you win more than you bid you get "bags" which equal 1 point, 10 bags will get your score reduced by 100 points, if you don't get as many tricks a syou've bid your score is reduced by how many you bid for x 10, so if you bid 4 and lost, your score will be -40 points.
Spades is in my opinion a game of both luck and strategy, if you're lucky you get high cards or lots of Spades, and after playing for a while you can begin to develop a strategy for playing your cards, so if anyone out there is looking for a new online game to play, both for real and/or play money, I believe that Spadester.com is well worth a try. You can join games that will only last 10 mins or the longer games can go on for 30 mins or until a points level is achieved. So come on you Poker people, at least give it a go, you've nothing to lose but 10 mins of your time.
