The Pivot & Defense Pack

The next step after The Rack-First Kit: 40 drills on the two decisions that come up in the middle of a hand. Should you stay on your line or switch? And which tile is safer to throw?

What's inside

• Part 1, Stay or switch (drills 1–20): two lines, the tiles each one still needs and what's already on the table. Is your line alive, dead or hanging by a thread?
• Part 2, Safer discards (drills 21–40): an opponent's exposures, the discards so far and four tiles. Which is safest and which is most dangerous?
• Answers with the reason why
• The Defense Card: front and back, plus a pocket version for the table

Good to know

• Instant download: 2 PDFs, 29 pages
• Built on the 2026 card. Drills show only the tiles you need, never a hand from the card
• Made for Rack-First Kit owners: it builds on the three checks in the Playbook
