Long Texas Hold‘em Tournament Structure

If you want to play a longer poker tournament that allows for a real battle of skill, start each player with 10,000 chips and play with 30- or 45-minute levels. Here is the structure for a serious tournament. If you want to make sure it lasts, allow players to re-buy until the first break.
If you're still playing beyond level 10, keep doubling the blinds every level from there until one player has all the chips.
