Note:
The number of high cards in holding 3 to a straight flush is roughly offset
by the number of gaps. When evaluating 3 to a straight flush subtract
the number of gaps from the number of high cards.
Terms:
High card:
A jack, queen, king, or ace. These cards are retained more often because
if paired up they return the original bet.
Outside
straight: An open ended straight that can be completed at either end,
such as the cards 7,8,9,10.
Inside
straight: A straight with a missing inside card, such as the cards
6,7,9,10. In addition A,2,3,4 and J,Q,K,A also count as inside straights
because they are at an extreme end.
Gap:
The number of ranks needed to fill in the middle of a straight flush.
For example a 6,7,8 would have 0 gaps, a 6,7,9 would have 1, and a 6,7,10
would have 2. The following are considered to have 2 gaps because they
are at extreme ends: A,2,3; A,2,4; A,3,4; J,Q,A; J,K,A; and Q,K,A. The
following are considered to have 1 gap because they are close to an extreme
end: 2,3,4 and J,Q,K.
Example:
Suppose you have the following hand.
kort kommer
här
The top two
plays are (1) keep the three to a straight flush and (2) keep two to a
royal flush. The number of gaps to the straight flush is 2 and the number
of high cards is also 2. So gaps-high cards=0. The table shows that 3
to a straight flush, where gaps-highcards>=0, beats two suited high
cards, so go keep the 3 cards to the straight flush.
