Great job!

For people not very into BJ - there are rules available with pretty binary decisions trees (depending on rules). Quick google search brought https://www.blackjackapprenticeship.com/blackjack-strategy-c... but there are plenty of other resources. Essentially, I believe there is always a perfect strategy available that should guarantee profit (given unlimited cash available to play unlimited game)

Without counting (which is not possible with this version since there is no shoe or deck to count from), optimal (basic) strategy will guarantee a loss in the long run. If there was a basic strategy which guaranteed profit for the player, no casino would offer this game.

With the set of rules implemented here, including early surrender and double after split, it seems perfect basic strategy, even without counting, gives a very minimal edge to the player.

Also, this version lets you count cards, since it uses a single deck and displays shuffles.

The perfect strategy is called "being the house"
