I was playing at a unnamed casinos that had a video UTHE. I have no idea what the correct strategy is for this game, but I was using a combination of Steve How's basic strategy along with J. Grosjean's strategy. If you assume the element of risk at 55 basis points, then I was playing with advantage between 2% to 4% due to promotions et al.

I don't play HE so I started learning the game using a basic strategy found on the internet (I knew it was incorrect, but it was a good place to start). Then I tried to learn the Wizard's strategy and that was hard. Next was Steve How's strategy and Steve's inability to discern absolute nut kickers from relative nut kickers was a problem. Then I decided on Grosjean's strategy except he omits certain information such as, but not limited to, counting flush out with 4-flush cards on the board. I liked the fact that each stage was a pure-math proposition bet.

Here are my observations:
(A) most traditional video poker players do not consider video UTHE as a video poker game, but they should add the game to their arsenal.
(B) I was playing mostly 400 to 600 hands (as much as 1,200 hands) of UTHE a day and that is a lot of HE hands.
(C) Steve How has the best public information on strategy deviations such as betting 4X on either J9o or K4o, etc.
(D) Grojean's strategy is really easy to learn and his emphasis on "outs" simplifies the Fold or 1X stage.
(E) It's easy to make fat finger mistakes since the design of the game does not allow for "undoing" an action.
(F) Despite the variance being under 6 units, the game is streaky and a 200-Ante buy-in may not be enough at times.
(G) The bad beats are nasty and frequent.
(H) Playing the board is tough since it comes down to the kicker: two-pair with ace kicker and it's a no-brainer to play the board; however, it takes discipline to fold knowing the odds are you will be outkicked.

I never hit the RF, but I did hit the STFL and Quads many times. I am burnt out so I am not upset the casino removed the game.

Cheers.

PS When the board shows 3 flush cards and you pair up with one of your hole-cards, it's not clear what the correct strategy is. For example, if you have the 7h3d as your hole cards and the flop comes KJ7s where you are now holding a pair of 7's, the correct play is to check rather than bet 2X. However, if your hole cards are 8h3d and the flop is KJ8s, you now bet 2X with your pair of 8's.

Also, if you have 7h3d and the flop is K75s where you are holding a pair of 7's, the correct play is 2X. In fairness, Steve How talks about this bottom pair issue versus 3 flush cards on the flop. Again, I do NOT know the correct strategy for this game, but it was fun playing with Grojean's basic strategy along with Steve How's insights.

UTHE is made up of three separate math-oriented proposition bets: (a) a 2-card hand, (b) a 5-card hand, and (c) a 7-card hand (which includes playing the board!). The 2-card hand is IMHO a game of copies, overcards, flushes, straight, etc. Here are the 2-card stategy deviations to basic strategy when playing 2-Hands at the same time (i.e. looking at 4 hole-cards) based on Steve How's work at discountgambling.net:

Check vs 4X
44 2 Copies
33 1 Copy
A2 1 High and 1 Low Copies
K7o 1 Low Copy of "7"
K6o 1 Any Copy
K5o 1 Any Copy
Q9o 1 Any Copy
Q8o 1 Any Copy
JTo 1 Any Copy

4X vs Check
K4o No Copies
Q6o 2 Overcards (A or K)
J9o No Copies

The basic strategy for UTHE is to bet 4X when you have a pair of 4's but if you see 2 copies, i.e., the remaining two 4's in your other hand, then you should check both hands as opposed to betting 4X for each hand. If you have Q9o in one hand and you see either a Q or a 9 in your other hand, then you should check the Q9o rather than bet 4X.

If you have K4o in one hand and don't see either a K or a 4 in your other hand, then bet 4X as opposed to check per basic strategy. If you have a pair of Aces in one hand and Q7o in your other hand, then bet 4X for both hands even though basic strategy tells you to check on Q7.

I'll share more hands when I get the chance. Video UTHE has a house edge similar to 9/6 JOB but comes with about 1/3rd the variance.

Cheers.

Reducing variance in video UTHE.

Most people don't understand that the weights are squared when calculating variance at the portfolio level. Steve How talks about the benefit of collusion or using more information at UTHE. In fact, Steve's simulations show that the variance of the game is reduced when using collusion. However, Steve does not show the math so here is the math for those that are curious:

When playing 2 hands at the same time:
Var(P) = W(A)^2*Var(A) + W(B)^2*VAR(B) + 2*W(A)*W(B)*Covariance(A,B)
sometimes you see the last term as 2*W(A)*W(B)*Stdev(A)*Stdev(B)*Rho(A,B) where Rho(A,B) is simply the correlation between A & B. Wikipedia has the formula for playing 3 hands at the same time and it's not hard to extend the formula to 4 hands or more, respectively.

(source: http://www.investopedia.com/terms/p/portfolio-variance.asp and http://en.wikipedia.org/wiki/Modern_portfolio_theory)

If you are playing two hands at the same time and making the same bet for each hand, the formula is reduced even further since the weight of (A) is now equal to the weight of (B). The key point to remember is the weights are squared at the portfolio level. One of the nice things about video UTHE was the ability to play horizontally as opposed to playing vertically in the case of N-play.

Cheers.

Some of the equity difference comes from the number of ranks that the dealer possibly could make a better pair with on future cards. With KJ7s, the dealer could possibly make a better pair with an Ace, Queen, Ten, Nine, or Eight on the turn or river. With KJ8s, then only an Ace, Queen, Ten, or Nine could possibly do it.

There was one in the all-video pit at Monte Lago when they reopened. I'm not sure if it's still there - havent been out that way in a couple years now.

The last one is at the Tropicana, $3 minimum.
I think it may be the last one in the state of Nevada..

Your methology is wrong. Each hand is dealt from a seperate deck. You may even be dealt the exact same thing in both hands



Are you sure? What deck are the shared community cards dealt from?

I believe those are chosen first.

And are all the UTH units dealt in this manner? I have heard that they do this, but I have never looked that in-depth into it.
