A2345 is +the second-highest straight (and straight flush), below TJQKA but above +9TJQK, by default. `PaiGowConfig.A2345High()` reads the optional +`a2345_second_highest` field (default true); the evaluator is threaded +through the `...Rules` variants (`pgEvaluateRules`, `pgHouseRules`, +`pgFortuneRules`, `pgBestRules`, `pgDealerPushRules`, +`pgMainResultRules`, `pgPushAceClassRules`) so a table can demote the wheel +to the lowest straight without changing the default wrappers the tests use. +Low hands recognize only pairs and high cards.

The main bet deals immediately when every active +(connected) player has one, and a lone bettor is dealt at once, so a single +seat never waits on a timer. With two or more active players the shared +betting window (`betting_ticks`) opens and `finishBettingLocked` deals when +it expires if any main wager is live, refunding side bets on seats that +never placed one. `unbet main|fortune|pushace|all` returns an undealt stake +through `PayCredits`, and `leave` before the deal refunds the departing +seat and re-checks `allBetLocked` so the remaining bettors can be dealt. +The Push Ace High cap (half the main wager) is enforced when the main wager +lands, because side bets are already down by then. ## House way |
