Second, and more importantly, the Nash-Shapley model also illustrates the importance of defending against the bluff, which represents strength when one is in fact weak, via slow-playing, which represents weakness when one is in fact strong, via an ”optimal slow-playing frequency”.
Quantized Poker
There are four such functions and the two that survive the process of eliminating of dominated strategies are playing directly, that is passing when holding an L and betting when holding an H (denoted in the tables as s1 ), and running a possible bluff, i.e. betting holding an L or an H (denoted in the tables as s2 ).
Quantized Poker
The poker lingo refers to this as snapping off player 3’s bluff and an early action player’s slowplaying strategy as sandbagging.
Quantized Poker
Note that attempting to snap off bluffs is not without risk, as player 3 may well pass out the hand when holding L and deny to players 1 or 2 their sure gain of at least half of players 3’s ante in the situation where at least one of players 1 and 2 bet holding H and player 3 holds L.
Quantized Poker
On the other hand, the rewards of successfully snapping off a bluff are great as if player 3 holding L does attempt a steal in response to a slowplay by one of players 1 or 2, he loses the maximum possible of an ante plus a bet to that player.
Quantized Poker
One can ask, just how often does this happen ? An easy application of Bayes’ Rule shows that in equilibrium the probability of at least one of players 1 and 2 is using his or her slowplaying strategy is about 28%, so player 3 can expect to have his bluffs snapped off a little more than a quarter of the time.
