Bags are the double-edged sword of Spades scoring. Every book past your bid is +1 point — but hit 10 bags and you lose 100. Good teams weaponize the bag rule. Bad teams get buried by it.
How bags stack
Every book taken beyond your bid is a bag. Bid 4, take 6 = 2 bags. Bid 3, take 3 = 0 bags. Bags accumulate across hands until you hit 10, at which point −100 is deducted and your bag count resets.
That means a team sitting at 9 bags is one book away from a 100-point disaster. And a team at 3 bags can afford to grab a couple extras without worry.
Weaponizing bags
Track the opponents' bag count. If they're near 9, dump extra books on them intentionally. Take books you'd normally let go. Force them into the penalty by making them win more than they bid.
'Bag dumping' is a strategy: when you have books you can't avoid taking, let the opponents take them instead. Play higher cards than you need to on their winning books to force them to take more.
Escaping the bag trap
If you're near 9, bid tight. Bid what you're absolutely sure you'll take, and no more. Actively avoid extra books — drop high cards when you can, let opponents grab loose books that would otherwise land on you.
Sometimes the right move is to overbid deliberately. If you're at 8 bags with a 5-book hand, bid 6 or 7. Making a 7-bid takes 0 bags. Bidding 5 and taking 7 takes 2 bags — enough to trigger the penalty.
