Chapters 4 — Odds in Texas Hold’em and 6 — Odds in
Omaha Hi-Lo — explain the odds of flopping Straight and
Flush draws, Straights and Flushes, and more.
After the Flop
Once the Flop has hit the board, you have 5 of the 7 cards
that will make your best and final hand. After the Flop and
with 2 cards to come, regardless of the hand, any player still
involved must know
1. The odds of improvement on the next card (the
Turn)
2. The odds of improvement over the next two cards
(the Turn and the River)
3. The odds of hitting certain Runner-Runner hands.
Odds of Improvement on the Turn
After the Flop, the calculation of the odds of improvement
with the next card is straightforward. The only number that
changes is the number of outs.
After the Flop and before the Turn, counting your 2 hole
cards and the 3 Flop cards, there are 47 unseen cards.
