LadderZine Strategy: Spades
If the total table bid is 12 or more, always try to set the opponents.
If the total table bid is 10 or below, always go for bagging your opponents.
If the total table bid is 11, then you must play it as you go: maybe set, maybe bag.
Never bid nil with more than three spades and no spade over the value of a Jack, unless in a win-or-lose situation.
As a general rule, when you are the fourth and final bidder, never bid more than a total table bid of 13.
