[Gamblor]

also to be considered is that gamblor and diplomat are well aware that if one person runs out of money on the trip he will be more likely to want to leave sooner in the evening, thus taking the other out of the game earlier.

Also, I had about 3500 behind on the turn, not 2350.

so, while they certainly don't intend to softplay each other, gamblor is aware that there is a reasonable (but not certain) chance that diplomat won't run a big bluff on him (and vice versa).
