A poker wager can increase without giving every player another chance to raise. A short all-in changes the amount to call, but the players facing it can have different options because they acted at different points in the betting.
The useful record is the sequence of amounts, including what each player last committed on this round. A single number beside an all-in label cannot explain the whole decision.
A raise to 500 can be a raise of 300
The Poker Tournament Directors Association's 2026 rules, version 1.1 dated 21 September, distinguish the size of a raise from the resulting total wager. Rule 45-A sets the minimum increase by the largest earlier full bet or raise on the current betting round.
Take an invented no-limit tournament hand after the flop. Assume a legal opening bet, clear declarations and action in order. Amounts below are totals committed on this betting round, not the whole pot. Everyone has sufficient chips for the stated actions except an explicitly all-in player.
| Player | Action this round | Result |
|---|---|---|
| A | Opens for 200 | The opening bet is 200 |
| B | Raises to 500 | The increase is 300 |
| C | Goes all-in for 650 | Another 150, below a full 300 raise |
| D | Has not yet acted | Faces 650; a full raise must reach at least 950 |
B's increase is 500 minus 200, or 300. Before C acts, the next full raise would reach 800. C's last 650 chips can still form a short all-in. That does not replace the last full increase of 300 with an increase of 150.
D can call 650 or, if raising, make a full raise to at least 950: the current 650 plus 300. Doubling C's total to 1,300 would produce a larger raise than the minimum. Adding just 150 to reach 800 would fall short of a full raise for D, assuming D has chips remaining.
These are invented tournament units, not quoted cash stakes or a record of a real hand. Our tournament-chip article separates those units from prize money.
A and B do not return to the same decision
Suppose D calls 650 rather than raising. The action returns to A, who last bet 200. B's full raise has already given A another raising opportunity. C's short all-in does not remove it.
If A simply calls the current 650, A adds 450. B then faces an additional 150 above B's earlier 500. That short increase does not reopen B's betting: B can match it or fold, but cannot raise in this stated sequence.
TDA rule 49-A measures reopening against a full bet or raise faced by a player who has already acted. D's opportunity to raise in the previous section came before D had acted at all. B's restriction follows a different action history, even though both faced the same current total of 650.
This concerns legal betting options, not which option is profitable. Our side-pot reconstruction follows the separate question of who can win chips after unequal contributions.
Two short all-ins can add up differently for different players
Change the sequence. A opens for 300, B calls 300, C goes all-in for 400, D calls 400 and E goes all-in for 600. The last full bet remains 300. C added 100 and E added 200; neither increase alone is a full 300 raise.
When the action returns, A and B each face 300 more than their earlier 300. Under TDA rule 49-A, that cumulative increase reopens their betting. Either can make a full raise to at least 900, the current 600 plus the last full bet of 300.
D last acted at 400. If A and B both just call 600, D faces another 200, below the 300 needed to reopen D's betting. D can call that 200 or fold. The same pair of short all-ins has therefore reopened action for A and B while leaving D without a raise in this branch of the example.
A later full raise would change the sequence again. The conclusion about D depends on A and B calling, not raising.
The named tournament rulebook still matters
The 2026 WSOP Official Tournament Rules, rule 96, also address short all-ins and cumulative reopening. Its own example has a bet of 500, a raise to 1,000, a call, then all-ins to 1,300 and 1,700. If the original bettor calls or folds, the players previously at 1,000 can raise. The minimum total is 2,200: 1,700 plus the last full raise of 500.
That is the WSOP's published example for its named Las Vegas series. The TDA is a voluntary tournament association whose rules require adoption by the event. Neither document automatically supplies the rules of every cash room or online client.
Limit poker also has a different reopening threshold: TDA rule 49-B specifies at least half a full bet or raise. Applying that threshold to the invented no-limit hands above would change the answer incorrectly.
In the first hand, 650 alone cannot explain why D can raise while B cannot. The missing information is who acted before the full raise and who has only faced the short increase since their last action.
