Blackjack basic strategy calculator & house edge simulator

Play real hands with the full action set. Every decision is graded against the derived strategy: you see the mathematically best play, the expected value of each option, and the dealer's odds for that upcard. EVs come from the solver's per-total tables, so on hands of 3+ cards they are indicative for the total, not the exact cards.

Simulates many independent sessions of a Hi-Lo counter playing the derived basic strategy: bets stay at the table minimum until the true count reaches the threshold, then scale by fractional Kelly on the count-derived edge. Ruin = bankroll can no longer cover the table minimum.
