## Official Casino Floor & TDA Ruling
Under TDA Rule 68 (One Player To A Hand) And Rule 69 (No Disclosure), Players May Not Consult Spectators, Charts, Solvers, Or Other Players During A Hand. No Player May Expose Hole Cards, Discuss Strategy, Or Speculate On Possible Hands While Any Live Multiway Or Heads-Up Action Is Pending, Particularly In Tournaments Where ICM And Elimination Equity Affect All Other Entrants. Under The Show-One-Show-All Rule, If A Player Intentionally Or Accidentally Shows Their Cards To Any Single Player At The Table At The Conclusion Of A Hand, Any Other Player May Demand That The Dealer Table Those Cards Face Up For The Entire Table.

## Frequently Asked Questions
### Can I Show My Cards To My Opponent In A Cash Game Heads-Up Pot?
Many Live Cash Rooms Allow A Player Closing The Action In A Strictly Heads-Up Cash Pot To Expose Their Cards Before Calling Or Folding, Provided No Third Player Remains In The Hand. In Tournaments, However, Exposing Live Cards Is Strictly Penalized.

### What Is Soft Playing And Why Is It Penalized In Tournaments?
Soft Playing Occurs When Friends Or Staking Partners Refuse To Bet Value Hands Or Check Down Strong Holdings Against Each Other. In Tournaments, Soft Play Colludes Against The Rest Of The Field's ICM Equity And Carries Penalties Up To Disqualification.
