A flush pays 2 in this game, and two deuces drawing three cards are worth more than that before a single card is turned over: any pair among the three new cards is four of a kind (5), a third deuce with anything is at least four of a kind and with a pair five of a kind (15), both remaining deuces are 200, and three suited cards inside a run are a straight flush (9) or a wild royal (25). The clubs you would keep do not help. Holding the king with the deuces, or two clubs for a 'four-card flush', only narrows the draw towards hands that pay 2 while blocking the four-of-a-kind draws that pay 5 and 15 — each of those holds is worth half a coin less than the deuces alone. The chart line is blunt about it: two deuces break a pat straight and a pat flush (a two-deuce full house cannot be dealt — two deuces with any pair are already four of a kind). The exceptions are the pat hands that already pay 9 or more (a wild royal, five of a kind, a straight flush) and the two-deuce draws that keep exactly two cards for a specific reason: a pair (four of a kind, draw one), two suited royal cards, or two suited touching cards 6-7 or higher.
Chart line #9 of 33 — 'Two deuces only — draw three (break a pat straight or flush)'. Lines #5–#8 above it list the only two-deuce holds that keep more. See the full solver-optimized strategy chart, or drill hands with exact-EV feedback until plays like this are automatic.
