Holding the pair of 4s has higher expected value than chasing a queen high hand; pairs of 4s draw to trips, full house, or quads.

No pair, flush draw, or straight draw worth keeping; the lone high card (Ks) has the highest expected value of any hold pattern here, so discard the other four.

Keeping the pair of tens with the spade flush draw gives high-pay two-pair/trips chances plus flush outs, beating a bare low pair.

Three to the royal flush (As, Js, Ts) has higher expected value than the lowly pair of aces, keeping royal, straight flush, flush, and straight draws live.

Low pair of nines has higher EV than holding the lone king; drawing to the pair gives chances at trips, full house, and four of a kind.

The pair of threes is a low pair, whose draw-three EV (~0.81 per credit) beats holding the queen alone (~0.47) or Q-T (~0.49); discard the 2s, Tc, and Qh.

Holding the low pair of fives and drawing three cards has EV ≈ 0.82 per credit (quads/full house/trips/two pair chances), well above the best alternative of two suited high cards (A♦Q♦, ≈0.59) or three unsuited high cards.

No high pair or viable draw; a lone ace has the highest expected value of any hold pattern here.

Holding the pair of kings (high pair) is clearly optimal; low pair 6 plus unrelated high cards has far lower EV.

Low pair of 9s has higher EV than the three-card royal (AcQc9c) in 9/6 Jacks or Better.

Pair of queens is a high pair, which outranks holding the suited A-Q; drawing three to the pair maximizes expected payout.

Holding both pairs and discarding the king kicker: any remaining 7 or 9 (4 of 47 cards) makes a full house, giving EV ≈ 12.98 credits versus a guaranteed 10 for pat two pair.

A low pair (fives) draws to two pair, trips, or a full house with EV ~0.82, well above the ~0.49 EV of holding just the unsuited K-J high cards, so keep only the pair of fives.

The pair of sixes is the strongest hold here; a low pair (EV ~0.82 per credit) beats holding two unsuited high cards like T-Q (~0.60), so I keep the sixes and draw three.

The pair of threes is the best hold: a low pair's EV (~0.82) beats the 3-card club flush draw (~0.64) and any straight draw here, and holding only the pair maximizes chances to draw trips, quads, or a full house.

High pair of queens outranks the two-card royal and low connectors in 9/6 Jacks or Better; drawing three gives chances at two pair, trips, full house, and quads.

The pair of 4s is by far the best hold: a low-pair draw has EV around 4.1 credits, beating every partial straight/flush option here (no 4-flush or 4-straight exists).

Dealt two pair (aces and twos); discarding the king and drawing one gives 4 outs to a full house (EV ~12.98 credits) versus a pat two pair worth only 10.

Holding the pair of tens and drawing three gives the best expected value (~0.82 per credit) via chances at trips, full house, or two pair; every alternative (kickers, suited T-8, or 7-8-T straight pieces) has far lower EV.
