Blackjack Even Money — Should You Take It?

When you have a blackjack and the dealer shows an Ace, you're offered even money — a guaranteed 1:1 payout instead of risking a push if the dealer also has blackjack. It's tempting because it feels safe. For basic strategy, the answer is usually decline.

Even money is insurance in disguise

Taking even money is mathematically identical to insuring your blackjack. In both cases you're being paid to bet that the dealer's hole card is a ten — and that bet loses money on average for the same reason insurance does: a ten-value card appears only about 30.8% of the time, below the break-even point.

The math

If you decline, your blackjack pays 3:2 (1.5 units) whenever the dealer does not have blackjack — about 69.2% of the time — and pushes the rest:

EV of declining ≈ 0.692 × 1.5 = 1.038 units
Even money        = 1.000 unit (guaranteed)

Declining is worth about 1.038 units versus the 1.0 even money locks in. You give up roughly 4% of the value of your blackjack by taking the "safe" money.

When even money is correct

Just like insurance, even money turns +EV only when the remaining shoe is genuinely rich in tens — something a card counter tracks. Off the top of the deck, or without counting, decline every time. Fullcount computes the live ten-density and the exact EV of each choice for the current shoe:

The instinct to "guarantee" a win is exactly what the offer is built to exploit. Take the 3:2 and let it ride.
