How should you play the early stages of a tournament?

Play them like a deep-stacked cash game. At 100 big blinds there is no ICM pressure, so every chip is worth the same as every other chip and you should take any edge that shows up. Open wide in late position, three-bet for value, and use the depth to set mine and play speculative hands in position.

Should you play tight in the early stages of an MTT?

Not tighter than position warrants. The early levels contain the weakest players in the field and the deepest stacks, which is the best combination you will see all tournament. Be selective out of position and disciplined in big pots, but folding your way through level 3 wastes the softest hours of the event.

Does ICM matter in the early stages of a tournament?

Barely. ICM says a chip you win is worth slightly less than a chip you lose, but hundreds of eliminations before the money that discount is far too small to change any decision. It only becomes a real constraint near the bubble and at the final table.

How deep do you need to be to set mine profitably?

You flop a set with a pocket pair roughly one time in eight and a half, so you want something near 15 to 1 in implied odds before calling a raise cold. At 100 big blinds a 2.5bb open leaves enough behind to make that work against a player who pays off. At 25 big blinds it does not.

Early Stage MTT Strategy at 100 Big Blinds Deep

The first few levels are the deepest you will ever play a tournament, and the field is never weaker. At 100 big blinds with the money hundreds of eliminations away, ICM is worth nothing, every chip is worth exactly one chip, and the correct strategy is a good deep-stacked cash game. Play position hard, three-bet for value, and stop treating survival as a plan.

The early levels are a cash game with a clock

Two things separate the opening levels from every stage that follows. Stacks are at their deepest, and the field still contains everybody who bought in — including the players who will be gone by level 6.

That combination is the highest edge per hand you get all tournament. A recreational player limping UTG with K♣9♦ and calling three streets is worth more to you at 100bb than at 25bb, because there is more money behind to win.

Nothing about the payout structure has bitten yet. Your stack has a chip value and almost exactly the same real value, so the only question on any decision is whether the play makes chips — the same question a cash game asks. That holds until when ICM starts to matter, which is nowhere near level 2.

The clock is the one real difference: blinds rise, so a stack that does nothing shrinks in real terms.

The survival myth

The most repeated piece of early-stage advice is that you cannot win a tournament on day 1 but you can lose it. It is half true, and the false half costs more.

Chips do have decreasing marginal value. Doubling your stack does not double your equity in the prize pool, because you can only win first place once.

A chip you win is worth slightly less than a chip you lose. At 100 big blinds with the bubble hundreds of players away, that discount is too small to change a single decision.

So take every clearly profitable spot. Decline a marginal flip only when a better one against a weaker player is genuinely coming, not because you feel fragile. Folding QQ in level 1 because there is no need to risk it is not caution, it is a leak with a story attached.

Opening ranges: position does the heavy lifting

At 100bb your opening range is decided almost entirely by seat. These are approximate 6-max numbers; nine-handed, shift each seat tighter and add two more early positions.

Seat	Roughly how many hands	Default open
UTG	15-17%	2.2-2.5bb
HJ	around 20%	2.2-2.5bb
CO	around 27%	2.2-2.5bb
BTN	40-45%	2.2-2.5bb
SB	35-40% raise-first-in	3bb

The gap between UTG and BTN is the single largest number in poker strategy. You play nearly three times as many hands from one seat as the other, against fewer opponents, with the last word on every street.

Live fields run larger opens — 3bb and up — and raising 3bb plus one big blind per limper keeps the price honest. If you want the specific hands rather than the percentages, the starting hand chart by position lays out each seat.

Three-betting 100 big blinds deep

Depth changes what a three-bet is for. At 20bb it is a commitment move. At 100bb it builds a pot you can still play three streets of.

Value comes first. QQ+, AK and AQs against a late-position open are three-bets, not calls. Flatting QQ in the big blind invites four overcard flops you cannot love.
Bluffs need blockers and playability. A5s, A4s, KQo and suited connectors block the top of the opener's range or flop well enough to keep barrelling. J8o does neither.
Size 3x in position, 4x out of position, adding a blind per cold caller. Out of position you need the extra size to deny them a price.

Value matters more than bluffs here because early-tournament opponents call three-bets far too wide. AK against QQ is 43/57 — a slight dog, not a disaster — and against the AJo and KQo that call you far too often, you are a big favourite.

The hands deep stacks reward

Depth also changes which speculative hands are worth playing, and small pairs are the clearest case.

You flop a set roughly one time in eight and a half, which needs about 15 to 1 in implied odds to call a raise cold. That is achievable at 100bb and impossible at 30bb, so set mining with small pairs is an early-stage play that quietly dies around level 8.

Suited aces and suited connectors gain for the same reason: they make hands that get paid — nut flushes, straights, two pair — and fold easily when they miss. Offsuit broadways lose, because they make second-best top pairs and nothing worth stacking off with.

More on how depth reshapes every street is in deep stack poker strategy.

Read the table before you need to

Early levels are the only time you will sit with the same eight players for hours. By level 3 every seat should be in one of three buckets.

Limpers. They call the first raise and fold to the second bet. Isolate them in position and value bet thinner than feels right.
Stationary callers. They will not fold top pair. Bet three streets with anything better and never bluff them.
Aggressive regulars. They three-bet light and barrel. Flat more of your strong hands and let them bet into you.

Those notes are worth most later, at 30bb, when reads replace the maths.

Protecting your stack without playing scared

There is one genuine tournament adjustment at this depth, and it applies to big pots rather than small ones: chip-EV and real EV diverge when the whole stack goes in, so the discipline belongs on stack-offs, not on opens, three-bets or continuation bets.

Do not stack off with one pair on wet boards. An overpair 200bb into the pot is a fold more often than players want it to be.
Take the flip when you are the favourite. AA against KK is 82/18 and you take it every time; A♦Q♦ against a tight UTG shove for 100bb is a fold.
Avoid dominated calls. Calling a raise with KJo out of position makes exactly the hand that loses a big pot.

That is the entire tax the format charges you here. Everything else is cash game poker.

When the early stage ends

The early stage ends at a stack depth, not a level number. Around 40 big blinds the three-bet stops building pots and starts being a commitment decision. Around 25bb, open-shoving enters your range and set mining leaves it.

Watch your own depth, not the clock. A stack that has grown to 180bb is still playing early-stage poker at level 9; a stack that has slipped to 35bb is playing mid-stage poker at level 4.
