wong
v.v. to watch a game of blackjack to see which cards have been played before you start betting. You do this to wait for a moment when you have a better chance of winning.
v. to observe a blackjack game without playing, entering only when the deck composition favors the player. Derived from the pseudonym of professional gambler Stanford Wong.
He prefers to wong into a game rather than play every hand.
Professional players often wong to avoid betting during unfavorable counts, though many casinos now have rules against mid-shoe entry.
While wonging significantly reduces the house edge by ensuring the player only participates in high-count situations, it also makes the individual highly conspicuous to casino security personnel.
The verb is intransitive when describing the general strategy, but can be used with 'in' or 'into' to describe entering a specific game.
