Which cards would you keep?
Try three Jacks or Better hands. Decide which cards to hold before opening each answer. Kept cards stay; the others are replaced once from the remaining deck.
These examples use Poker Gym’s single 52-card deck and the pay table below. They teach this simulator’s decisions; they are not a universal strategy chart for other pay tables.
1. A paying pair
J♠ J♥ 2♦ 5♣ 9♦
Keep both jacks, just one, or all five?
Reveal the hold and explanation
Hold J♠ and J♥. Replace the other three. The pair already qualifies for a payout. Keeping unrelated low cards takes away chances to improve. For this exact hand, holding the pair has the highest average payout among all 32 possible holds.
2. A low pair and a tempting ace
7♠ 7♥ A♦ 4♣ 10♦
A pair of sevens alone pays zero. Does that mean you should keep the ace instead?
Reveal the hold and explanation
Hold 7♠ and 7♥. Replace the other three. A hand that pays nothing now can still be the best starting point. The pair can improve into two pair, three of a kind, a full house or four of a kind. For these exact five cards, the low pair beats holding the lone ace in average payout.
3. Four cards to a royal flush
10♠ J♠ Q♠ K♠ 2♥
Which card would you replace?
Reveal the hold and explanation
Hold all four spades. Replace 2♥. A♠ completes a royal flush. Other replacements can make a straight, a flush or a paying pair. Drawing one card leaves 47 equally likely replacements, with only one completing the royal. The best hold still gives no guarantee about the next card.
Check the rules before comparing decisions

The simulator’s coach compares every hold by averaging payouts over all possible replacement combinations. Holding more cards does not increase the bet. Average payout is not net profit: a return of one credit per credit would simply recover the stake.
Practice the decision, then review the reason. A lucky result can follow a poor decision, and a good decision can still produce a losing hand.
