Double Bonus supplement 1: Exceptions to Jacks Or Better strategy


The differences between the Jacks Or Better and Double Bonus paytables necessitate a few changes to Jacks Or Better strategy in order to achieve optimum return in Double Bonus. Please be aware that you can actually ignore ALL of the following, play standard Jacks Or Better and still achieve a very high payout. I'm listing the average "cost" of each mistake - assuming you make the incorrect play - in coin size; if the miss-play is listed as 0.20 (one fifth of a coin) and you're playing $1 per coin ($5 total wager with maximum coins played), the cost is $0.20, or twenty cents. There is also an example given of each play:

• If you hold a full house comprised of three aces and a pair, drop the pair and hold the three aces only. Cost of error: 3.34 coins. (This is an EXPENSIVE difference, because of the high payoff on four aces.)


Double Bonus
As, Ah, Ac, 8c, 8h. Hold the three aces

Jacks Or Better
As, Ah, Ac, 8c, 8h. Hold all five cards


•  Hold an open straight queen-high with three high cards over a pair of 9s. Cost of error: 0.2 coins.


Double Bonus
9s, 10h, Jc, Qs, 9c. Hold the open straight Q high

Jacks Or Better
9s, 10h, Jc, Qs, 9c. Hold the pair of 9s


• Hold an inside straight king-high with three high cards over a three straight flush, spread 5, one high card. Cost of error: 0.22 coins.

Double Bonus
7c, 9c, Jc, Qh, Ks. Hold the inside straight

Jacks Or Better
7c, 9c, Jc, Qh, Ks. Hold the three straight flush spread five


• Hold a single ace over Q10 suited. Cost of error: varies depending on the discards, ranging from under 0.007 to over 0.14 coins.

Double Bonus
Qc, 10c, Ad, 6h, 3h. Hold the single ace

Jacks Or Better
Qc, 10c, Ad, 6h, 3h. Hold the Q10 suited


• Hold QJ unsuited over a three straight flush, spread 4, no high cards. Cost of error: ranging between 0.005 and 0.04 coins.

Double Bonus
Jc, Qd, 4s, 5s, 7s. Hold the JQ offsuit

Jacks Or Better
Jc, Qd, 4s, 5s, 7s. Hold the three to a straight flush spread four


• Hold QJ unsuited over a three straight flush queen-high, spread 5, 1 high card. Cost of error: ranging between 0.016 and 0.036 coins.

Double Bonus
Jc, Qd, 9d, 8d, 4s. Hold the JQ offsuit

Jacks Or Better
Jc, Qd, 9d, 8d, 4s. Hold the three to a straight flush spread five


• Hold 10J suited over a three straight flush, spread 4, no high cards, except 568 and 578. Cost in coins: ranging between 0.0008 and 0.02.

Double Bonus
Jc, 10c, 3d, 4d, 6d. Hold the J10 suited

Jacks Or Better
c, 10c, 3d, 4d, 6d. Hold the three straight flush cards


• Hold an inside straight, king high with two high cards over two high cards by themselves. Cost in coins: 0.0012.

Double Bonus
9c, 10d, Jh, Kc, 4s. Hold the inside straight

Jacks Or Better
9c, 10d, Jh, Kc, 4s. Hold the JK unsuited


There is one additioan variation, holding a single ace rather than ace plus unsuited jack, queen or king. This one is slightly more complex and at the same time very, very inexpensive when played incorrectly. The precise rules are explained on the Double Bonus supplement 2 page.
