> Source: [Substantial Action & The TDA First-Card Rule on Smarter.Poker](https://smarter.poker/rules/first-card-off-the-deck-and-substantial-action) | Official Reference: TDA Rule 32 & Rule 36 / RROP Section 4

## Direct Answer & Summary Ruling
A Hand Officially Begins When The First Riffle Of The Shuffle Starts Or The First Card Leaves The Deck; Once Substantial Action Occurs (2 Actions With Chips Or 3 Total Actions), A Misdeal Cannot Be Called.

## Official Casino Floor & TDA Ruling
Under TDA Rule 36 (Substantial Action), Substantial Action Has Occurred When Either: (A) Any Two Actions In Turn Occur, At Least One Of Which Puts Chips Into The Pot (Bet, Call, Or Raise); Or (B) Any Combination Of Three Actions In Turn Occurs (Check, Bet, Raise, Call, Or Fold). Once Substantial Action Has Occurred On The Preflop Street, A Misdeal Cannot Be Declared For Wrong Button Position Or Deal Irregularities, And The Hand Must Be Played To Completion Unless The Deck Itself Is Fouled. Under TDA Rule 32, A Player Must Be At Their Seat When The Final Card Is Dealt To The Button To Have A Live Hand.

## Common Live Table Scenarios & Rulings
1. **Scenario**: UTG Folds And UTG+1 Calls The Big Blind Before Anyone Notices The Dealer Button Was Not Moved From The Previous Hand.
   - **Official Ruling**: Because Two Actions Occurred And One Put Chips Into The Pot (Fold + Call), Substantial Action Has Occurred. The Hand Plays Out As Dealt, And The Button Stays In The Same Spot For The Next Hand To Correct Position.
2. **Scenario**: UTG Folds And UTG+1 Folds Before A Player Notices Seat 5 Was Accidentally Skipped In The Deal.
   - **Official Ruling**: Only Two Folds Have Occurred (Zero Chips Put In And Fewer Than Three Total Actions). Substantial Action Has NOT Occurred, So The Floor Calls A Misdeal And Re-Deals.
3. **Scenario**: A Player Walking Back From Break Is 6 Feet Away From Their Chair When The Dealer Pitching The Final Card To The Button Releases The Card.
   - **Official Ruling**: Under TDA Rule 32 (At Your Seat), Because The Player Was Not Physically At Their Seat When The Last Hole Card Was Dealt, Their Hand Is Immediately Mucked Dead By The Dealer.

## Frequently Asked Questions
### Does Posting The Small Blind And Big Blind Count Toward Substantial Action?
No. Forced Blinds And Antes Posted Before The Deal Never Count Toward The Two-Action Or Three-Action Threshold For Substantial Action.

### What Counts As Being "At Your Seat" Under TDA Rule 32?
A Player Must Be Within Reach Of Their Chair (Able To Touch Their Chair Or Table Spot) Without Delaying The Game When The Dealer Deals The Final Card To The Button.
