Blackjack Strategy With Cards Already Seen

The basic strategy chart answers "what's the best action on average, knowing nothing else about the shoe". But at a real table, you've already seen several cards before deciding: your own, the dealer's and, if you pay attention, other players'. Those removed cards can, in extreme cases, shift the optimal action.

Why shoe composition matters

The general chart uses a standard industry simplification: it doesn't remove the player's two cards from the shoe when computing the dealer's distribution, so it can generate a single reusable table for any hand of that total. That's accurate enough the vast majority of the time, but it isn't the most exact calculation possible.
The live advisor does the more precise calculation: it removes every card you've logged this round from the shoe (your entire hand, the dealer's, and other players' if you log them) before computing the recommendation. The more cards of a given value are already visible, the more this removal can pull the real probability away from the chart's generic average.
In practice, for a 6-8 deck table, the difference rarely changes the recommended action, the effect of removing 2-6 cards from a 300+ card shoe is small. On single or double-deck tables, especially near the end of the shoe, the effect becomes much more visible, and that is exactly where composition-dependent calculation pays off most.

When this matters most

Large shoe

Input: 6-8 baralhos, poucas cartas vistas
Expected output: Recomendação quase idêntica à tabela geral

Small composition effect.

Small shoe

Input: 1-2 baralhos, várias cartas altas já vistas
Expected output: Recomendação pode divergir da tabela geral

Stronger composition effect.

Full tool FAQ

What's the difference between this tool and the Blackjack Basic Strategy chart?

The basic strategy chart is a general reference, computed assuming only your hand and the dealer's upcard are known. This advisor tracks the actual round: it removes every card you've seen from the shoe (your full hand, the dealer's card, and optionally other players'), giving a more precise recommendation for that specific moment.

Do I need to log other players' cards?

What happens when I split a pair?

Why does no recommendation show up sometimes?

Is the shoe remembered between rounds?

How many cards does a split Ace get?

What does "soft" next to a hand's total mean?

Does this recommendation guarantee I'll win the hand?

Frequently asked questions

Is this the same as card counting?

It's the same underlying math (the remaining shoe's composition affects probability), but applied only to the current round, without tracking the shoe across rounds or suggesting bet sizing, the two pillars of an actual card-counting system.

Is it worth logging other players' cards?

It's optional, and the precision gain is usually small at multi-deck tables. It's more worthwhile at single or double-deck tables, where each removed card carries more weight in the calculation.

Does the recommendation change with every card I log?

Yes, it's recomputed after every card, but in most cases the recommended action stays the same; it's the exact expected value of each alternative that shifts.
