A-K-Q-J unsuited — keep all four or just two?
Keep all four. The inside straight draw A-K-Q-J is worth 0.5957 per coin exactly — more than K-Q-J (0.4829) or any two high cards (0.4788). It's the only 4-card inside straight most simple charts get wrong.
The exact numbers — A♥ K♦ Q♠ J♣ 9♣

Four high cards pay their own way while you draw at the straight: any pair among A/K/Q/J returns even money, and the ten completes a 4-coin straight. That double duty is why 'inside straights with 3+ high cards' earned a line on our solver-optimized chart while ordinary inside straights stay unplayable.
Chart line #14 of 18 — '4 to an inside straight, 3+ high cards' (a line the classic 16-line simple strategy is missing; adding it is worth +0.025% exactly). See the full solver-optimized strategy chart, or drill hands with exact-EV feedback until plays like this are automatic.
