Rundowns

Connected rundowns (J♥ T♥ 9♠ 8♠) flop wraps and strong draws. Disconnected junk (J♣ 8♦ 4♠ 2♥) flops garbage. Suits multiply the value of rundowns.

Sucker alert: holding 6♠5♠4♥3♥ on a board 9♣8♦7♠ can make a straight that loses to higher wraps. Count which end you make before stacks go in.

Another flop: JT98ds on 6♦5♣4♠ — wrap heaven. Same hand on A♠K♦Q♣ — you flopped a straight but the board is ultra coordinated; someone else may have better/reds. Nutted doesn't always mean 'ship without thought' multiway when re-draws abound — but you are still way ahead of random.
