Can a player go all-in for less than a full raise and reopen betting?

How to use this answer

This answer is based on the mathematical principle or published rule identified in the source below. If the question involves a live betting market, confirm its settlement definition before applying it to a specific bet.

Usually not; a short all-in is not a full raise, though cumulative short raises may affect action under house rules.

Tournament rules are a useful reference, but a home game or cash game can have different house rules. Make the chip amounts, action sequence and card visibility clear before deciding a disputed hand.
