> Source: [Minimum Raise & Incomplete All-In Reopen Rules on Smarter.Poker](https://smarter.poker/rules/minimum-raise-and-incomplete-all-in-reopen) | Official Reference: TDA Rule 43 & Rule 47 / RROP Section 14

## Direct Answer & Summary Ruling
A Legal Minimum Raise Must Equal At Least The Size Of The Largest Previous Bet Or Raise Increment On The Current Street; An All-In Wager Of Less Than A Full Raise Does Not Reopen Betting For Players Who Have Already Acted.

## Official Casino Floor & TDA Ruling
Under TDA Rule 43 (Raise Amounts) And Rule 47 (Re-Opening The Bet), In No-Limit And Pot-Limit Games The Minimum Raise Increment Is Equal To The Largest Prior Full Bet Or Raise Increment Of The Current Betting Round. If A Player Goes All-In For An Amount That Exceeds The Previous Bet By Less Than The Minimum Legal Raise Increment (An "Under-Raise" Or Incomplete All-In), Players Who Have Already Acted And Are Facing Less Than A Full Raise Increment May Only Call Or Fold; They May Not Re-Raise Unless Another Player Behind First Makes A Full Legal Raise Or Multiple Short All-Ins Accumulate To Equal A Full Raise Increment.

## Common Live Table Scenarios & Rulings
1. **Scenario**: In A 100/200 Game, Player A Opens To 500 (A 300 Raise Increment). Player B Wants To Make A Minimum 3-Bet.
   - **Official Ruling**: Because The Previous Raise Increment Was 300 (From 200 To 500), Player B Must Raise By At Least 300 More, Making The Minimum Legal 3-Bet Total 800.
2. **Scenario**: Player A Opens To 600 (In A 100/200 Game, 400 Increment). Player B Shoves All-In For 850 (Only A 250 Increase). Everyone Folds Back To Player A.
   - **Official Ruling**: Because 250 Is Less Than The 400 Minimum Raise Increment, Betting Is NOT Reopened For Player A. Player A May Only Call The Extra 250 Or Fold.
3. **Scenario**: Player A Opens To 600 (400 Increment). Player B Shoves For 850 (+250), And Player C Behind Shoves For 1,050 (+200 More, Total +450 Over Player A).
   - **Official Ruling**: Under TDA Rule 47B, Because The Combined Short All-Ins Total +450 (Which Exceeds The 400 Minimum Increment), Action IS Reopened For Player A To Re-Raise.

## Frequently Asked Questions
### What Is The 50% Rule For Unclear Chip Raises?
Under TDA Rule 45B, If A Player Puts Out Multiple Chips Without Speaking And The Total Amount Includes At Least 50% Of The Minimum Raise Increment, The Player Is Required To Add Chips To Complete A Full Minimum Raise.

### Can A Player Who Has Not Yet Acted On The Street Still Raise Over A Short All-In?
