Model used: Benchmarks use six decks. The no-bonus model awards no extra amount for a second tie; the liberal model awards one original unit. The usual tie bet pays 10:1.
How a round works
First cardsThe higher rank wins one unit; suits do not matter.
Initial tieChoose surrender—losing half the original wager—or add an equal wager and go to war.
War resultAfter the stated burn procedure, a player tie or higher usually wins the added wager while the original pushes; a lower card loses both.
Practical strategy
- Go to war rather than surrender under the standard six-deck rules.
- Verify the second-tie bonus because it changes the price of the base game.
- Evaluate the tie wager independently; the intuitive frequency does not justify the usual 10:1 payout.
