Flopping a Straight Flush .. hand 6...... 09 01 25

In Texas Hold'em, flopping a straight flush means your two hole cards and the three community cards on the flop combine to form five consecutive cards of the same suit. It is one of the rarest and most powerful hands in poker.
Odds of flopping a straight flush
Your chances depend on your starting hand, specifically if you hold "suited connectors"—two cards of the same suit and consecutive rank.
Starting Hand Odds of flopping a straight flush
Suited connectors (e.g., 7♠ 8♠) 1 in 4,900 (0.02%)
Suited one-gappers (e.g., 7♠ 9♠) 1 in 6,665 (0.015%)
Suited two-gappers (e.g., 7♠ T♠) 1 in 9,999 (0.01%)
Suited three-gappers (e.g., 7♠ J♠) 1 in 19,999 (0.005%)
Strategic considerations
Because flopping a straight flush is so rare, you should not be actively playing hands with the sole purpose of hitting one. Instead, you should focus on the many other ways a strong suited connector can win.
Implied odds: When you do flop a straight flush, the implied odds are fantastic. Your opponents often hold strong, but second-best, hands like lesser flushes or full houses that they will be inclined to pay off.
Betting strategy: When you hit such a rare and powerful hand, you want to build the pot as large as possible. Be careful not to scare off your opponents by betting too aggressively.
