simple game theory question

The main author Martin Zinkevich (who came up with the new method) has since moved to work for Yahoo so unfortunately, he's not here anymore. The others, however, are all still here (although the Godfather and creator of the group, Darse Billings, is about to move to work for Full Tilt Poker). I attend their weekly Poker Group meetings.

Regarding the second question, on the next paragraph, he mentions exactly what you are talking about (what he meant by four betting rounds was that on each street, there is also betting, as some research previously has omitted one round of betting due to computational resource constraints):

Early poker abstractions [2, 4] involved limiting
the possible sequences of bets, e.g., only allowing three bets per round, or replacing all first-round
decisions with a fixed policy. More recently, abstractions involving full four round games with the
full four bets per round have proven to be a significant improvement [7, 6]. We also will keep the
full game’s betting structure and focus abstraction on the dealt cards.
