Why not just use an unabstracted preflop, assuming disconnected rounds?

No, haven't tried that. So far have only been using E[HS] and E[HS^2] for preflop bucketing.

Did you try to play preflop with hand strenght ?
Is it better than a static approach like "Sklansky tables" or is it similar?

The only explaination I have is that the authors actually mean to have only 1/2 of the total ties in the denominator.

There is another article that has exactly such formula.

And here is another person that uses the formula with 1/2 ties in the denominator.

ppot and npot

2013-06-12T10:29:17+00:00

Hello.

I'm looking at the "Opponent Modeling in Poker" paper (http://www.cs.virginia.edu/~evans/poker ... llings.pdf). On page 4 there is code for ppot and npot as well as an example breakdown for AdQc+3h4cJh.

Code:

         Ahead     Tied     Behind     Sum
Ahead    449005    3211     169504     621720
Tied     0         8370     540        8910
Behind   91981     1036     346543     439560

Rows correspond to where the hand was on flop and columns correspond to where it went on river. My problem is that the paper says ppot_2 = 0.208. But when I put the numbers into the formula I get a slightly different number:
(91981+1036*0.5)/(8910+439560) = 0.20625...

Am I doing something wrong?
