When is the best time to build up your stack in a tournament - early or middle stages?

In MTT tournaments, he noticed that many players play too passively at the beginning levels. I think it's a mistake not to take advantage of when we have deep batteries to press with position. Do you prefer to build stack early or wait for mid-stages?

Mid, early is too early to make a real difference in your tournament results.

In the middle stage, at the initial stage, it is better not to risk a lot of volume.

For obvious reasons its easier to win big pots, when the blinds have gone up. So no the early phase of a tournament is not the best time to build up your stack. But of course you should still look for any profitable spot, that might come up.

The best time is usually the middle stage.

Early on, stacks are deep and there’s less need to take risks.
In the middle stage, blinds increase and many players make mistakes — great spot to build chips.
You can apply pressure and pick up pots without huge risk.

Late stage is more about survival and ICM, not big chip accumulation.

In MTTs, I often notice the same pattern: in the early stages, many players are too passive, just trying to “survive” and avoid getting involved in hands. At first, I thought I should always take advantage of this and build my stack aggressively right away.
Now I see it in a more balanced way. Yes, the early stage is an opportunity. Stacks are deep, I have room to maneuver, and if there are weak or tight players at the table, I can apply pressure—especially when I’m in position. I open more often from late positions, make continuation bets, and pick up small pots without showdown.
At the same time, I remind myself that you can’t win a tournament in the early stages, but you can definitely lose it. That’s why I don’t force the action or build big pots without a strong hand, especially against unknown opponents. If a situation is unclear, I’d rather fold and preserve my stack.
I’m not playing passively, but I’m also not applying pressure without a reason. I choose my targets—mainly players who are too cautious and tend to fold. Against more aggressive or unpredictable opponents, I play more carefully.
In the end, I do try to build my stack from the early stages, but I do it selectively. If a good opportunity comes up, I take it. If not, I’m patient. For me, maintaining stability and control is more important than trying to win all the chips right away.

For me, the early stages are the best time to build your stack — and I think this is an underappreciated edge that a lot of recreational players miss.

The most common misconception I see is that the early levels "don't matter" because the blinds are so small relative to your stack. But that's exactly what makes them valuable. When everyone is deep-stacked and the pressure is low, you have the most room to maneuver. You can call with speculative hands like suited connectors and small pairs, look to flop big, and win large pots without risking your tournament life.

The players who wait until the middle stages to "start playing" are already at a disadvantage. By then, the stacks are shallower, the decisions are more binary, and the margin for error is much smaller. Building a big stack early gives you a cushion that allows you to apply pressure throughout the middle stages and approach the bubble from a position of strength rather than survival mode.

There's also a psychological element. Coming into the middle stages with a above-average stack completely changes how you play and how opponents perceive you. You become the threat at the table instead of reacting to others.

That said, "building early" doesn't mean gambling or playing recklessly. It means being attentive, identifying the weakest players at your table quickly, and putting yourself in high-equity situations whenever they present themselves.
