Stand.Why basic strategy says stand
Twenty wins against every dealer total except 21. Breaking it into two hands that start from ten gives up a near-certain winner for two uncertain ones.
Only an extreme positive count justifies splitting tens, and that is advantage play, not basic strategy.
Engine explanation: Stand with a pair of 10s against 6. Keep this total under the selected rules. This is a long-run basic-strategy decision, not a prediction of the next card.

Why should you never split 10s?
Because a hard 20 wins the great majority of hands, and two hands that each start on ten are worth less in total than the one 20 you give up, against every dealer upcard. Splitting 10s against a 6 does win money, but less than standing wins, so it is still a mistake. It is also a reliable way to irritate the rest of the table. The only people who split 10s correctly are card counters in a very high count, and even then only against a 5 or 6.
Training rules: six decks · dealer stands on soft 17 · no surrender
This is a separate educational profile. Rules can differ between app tables and other games.
- Six decks. Dealer stands on all 17s, including soft 17.
- US hole card and peek: decisions assume the dealer has checked and does not have blackjack.
- Double any first two cards, including after splitting. Doubling ends the hand after one extra card.
- Split equal card values into at most four hands. Split aces receive one card each; no resplitting aces.
- No surrender. A natural blackjack pays 3:2; 21 after splitting is not a natural.
- Total-dependent strategy. No card counting or expected-value estimates.
