To use this strategy look up all reasonable ways to play a hand and
choose the play that is highest on the list. If your hand isn't on
the list then it should never be played. The numbers on the right
represent the average return. These numbers can vary depending on
the discards.
Let's try an example. Suppose you have both four to a flush and a
low pair. Should you sacrifice the low pair to complete the flush
or sacrifice the possible flush and keep the low pair. From the list
below 4 to a flush has a higher ranking and thus is the better play.
To test yourself on other hands try my video
poker quiz.
I admit this is a long and rather difficult strategy but I believe
it correctly advises every possible hand. If used correctly it should
yield perfect play.

and the unsuited card is a 10 or straight penalty card.
- B
- 4 to an inside straight beats suited jack and queen with 9 or
flush penalty card.
- C
- 3 to a straight flush, spread 5, with 1 high card vs. 4 to an
inside straight, with 3 high cards: Play the straight flush if there
is no straight penalty card.
- D
- Suited 10 and jack vs. an unsuited jack and king: If there is
no flush penalty card then keeping the 10 and jack then that is
the better play, otherwise keep the jack and king.
- E
- Suited 10 and queen vs. an unsuited queen and ace: If there is
no flush penalty card then keeping the 10 and queen then that is
the better play, otherwise keep the queen and ace.
- F
- Suited 10, king vs. king only: Normally the suited ten and king
is better than the king alone, however if you must discard a 9 and
a flush penalty card then hold the king only.
Key:
- T
- 10
- J
- Jack
- Q
- Queen
- K
- King
- A
- Ace
Hands that are never played:
By request I have removed hands that are never played from the list.
Either some subset of these hands are better than the larger hand,
or discarding everything is better. In parenthesis I put what you
should do with these hands.
- Suited 10 and ace (keep the ace only)
- 3 unsuited high cards, ace highest (keep the lowest two high cards)
- 4 to an inside straight, 2 high cards (keep the two high cards)
- 4 to an inside straight, 1 high card (keep the single high card)
- 4 to an inside straight, 0 high cards (discarding everything)
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 (7,8,9,10).
Inside straight: A straight with a missing inside card, such
as (6,7,9,10).
Spread: This refers to the number of ranks spread apart the
cards are toward a potential straight, straight flush, or royal flush.
The smaller the spread the better the odds are for the player. For
example a suited 5, 6, an 8 would be 3 to a straight flush with a
spread of 4 because they cards span 4 ranks.
Penalty card: Sometimes one must discard a potentially useful
card. In rare situations cards you would never keep can still tip
the scales in favor of one hand over another. For example take the
situation in footnote F. The player has a king of clubs, 10 of clubs,
9 of spades, 6 of clubs, and a 3 of diamonds. The best options are
to either keep the suited 10 and king or the king only. The suited
10 and king is usually the better option. However in this scenario
two potentially useful cards would be discarded, the 9 (lowering the
odds of forming a straight), and the 6 of clubs (lowering the odds
of forming a flush). These two penalty cards degrade the value of
the suited 10 and king to below that of keeping the king only.
It
should be mentioned that this strategy is mainly for academic interest
or
only the most avid video poker players. For practical
purposes I recommend my simple
strategy with
a return of 99.46% or my intermediate
strategy with a return of 99.52%.
Methodology
To determine the above strategy I created a program can determine
the expected return of the best play of any hand. The way it works
is to consider all 32 ways to play a hand. For every play the program
systematically scores the held cards with every possible set of discards
and averages the results. The play that yields the greatest average
is determined to be the best play and the specific statistics for
that play are displayed. The program can also show the statistics
for non-optimal plays. Using this program it was then a time consuming
task to try numerous borderline hands and rank them in order of expected
return. I used Bob Dancer's 9/6
Jacks or Better Video Poker report to verify my strategy. There
I found some obscure exceptions that I did not notice, which I used
to correct my strategy. So I would like to thank Bob Dancer for his
help. You may order his software and strategy cards here.
