I'd call that a charged situation, sure. With the craps game, you could just play it out, which could be fun. With cards, I'd elid the actual cards:
"It's Dremmer (PC), Blue, Shit-head and Mason (PC), playing for a 3-gallon jug of clean water. The water sits in the middle of the table, beads of oily grey condensation starting to drip on the outside. Mason, you and Dremmer need to win this bad. Your hand's a bit on the low side. Blue's mouth is twitching ever so slightly. What do you do?"
And from there, it's a read a sitch on the game, read a person on the other players, maybe an open your brain and see if you can see the other player's cards, maybe even and act under fire to bluff convincingly.
If it's actually PC v PC, try this:
"It's down to Dremmer and Mason, playing for a 3-gallon jug of clean water. The water sits in the middle of the table, beads of oily grey condensation starting to drip on the outside. Mason, you need to win this bad. Blue's mouth is twitching ever so slightly. What do you do?"
Same options as above.
