Cribbage Hand Trainer

Deal a random 6-card hand, click 4 cards to keep, then check how your discard compares to the optimal choice.

Role:
Hands: 0 • Optimal picks: 0 • Avg gap: —

How to Use the Hand Trainer

  1. Set your role (Dealer or Pone) — affects crib adjustment in the scoring
  2. Click Deal Hand to receive 6 random cards
  3. Click 4 cards to keep — these are your “hold” cards
  4. Click Check My Choice to see the optimal keep and your score gap

Repeat until the average gap drops below 0.5 — that’s the mark of a strong discard player.

Reading the Results

MetricMeaning
Hand EVAverage hand score across all 46 possible starters
Crib adj.Estimated points from your discard (+ for dealer, – for pone)
Total EVThe combined expected value — this is what to optimize
GapDifference between your pick and the optimal; lower is better

A gap below 0.5 is near-optimal — both keeps are reasonable choices in real play. A gap above 2.0 indicates a significant strategic error worth studying.

Tips for Faster Improvement

Count first, then decide. Before clicking Keep, try to count all six possible 4-card combinations in your head. Which scores most on its own? Which discard is safest?

Watch the crib adjustment. Beginners often find a great 4-card hand but donate a 5 to opponent’s crib, swinging the game 7 points.

Learn from big gaps. When the gap is over 2 points, study the optimal keep carefully. Ask: “Why does that combination score more?” The answer is usually fifteens or runs you missed.

For the theory behind these decisions, read the Discard Strategy guide or use the Discard Advisor for full EV tables.

Frequently Asked Questions

How does the cribbage hand trainer work?
The trainer deals you a random 6-card hand. You click 4 cards to keep (your discard decision). When you click Check, the trainer reveals the optimal keep (highest total expected value) and shows you how your choice compares — including the hand EV and crib adjustment for both your pick and the best option.
What does the score gap mean?
The score gap is the difference in Total EV between the optimal keep and your chosen keep. A gap of 0 means you found the best option. A gap under 0.5 means your choice was very close to optimal — both are reasonable in practice. A gap over 2 points suggests a significant strategic error worth studying.
Should I choose dealer or pone before each hand?
Yes — it changes the crib adjustment. As dealer, you want discards that help your crib (5s, pairs, connected cards). As pone, you want discards that minimize crib damage. Set your role before clicking Deal.
Is the trainer suitable for beginners?
Yes. The trainer shows you the optimal answer immediately after each decision, with a score breakdown. Beginners learn fastest by: making a choice, checking the optimal, reading why it’s different, and dealing again. 10-20 practice hands per session will rapidly improve your discard intuition.
