John Douglas wrote about the article:
Hold W789 if the fifth card is a 3 (any suit) or a 4 totally unsuited with other cards in the hand.
Correction: When there's a 3, you hold the deuce only.
John is correct: the line should say "Hold W789 if the fifth card is a Q, K, or A (any suit) or a 4 totally unsuited with other cards in the hand".
Also, one of the 4-card inside straights listed in A1 was a typo. I appreciate these being pointed out. I'll have the corrected article reposted on Monday.
