The WSOP Main Event allowing late registration on Day 2 is nothing short of a mockery of the game. Tournament poker is supposed to offer a level playing field — not tilt the advantage toward wealthy pros who max-late-reg for a strategic edge.

Late registration is one of the most controversial issues in modern poker. Why do poker rooms even allow players to join after cards are already in the air? Is there actually an edge to entering late? Or are you just giving up valuable chips and EV? In this topic, we break down the pros, cons, and ICM implications of late reg — and whether it's helping or hurting the game.

Anyone who's played poker seriously knows: the deeper the stacks, the more skill matters. So why do so many tournaments offer extremely long late registration periods? And why do top-tier pros often wait to enter until they're stuck with a much shorter stack?

There was a time when late registration wasn't such a big deal — Phil Hellmuth was practically the only one showing up late to events. But now? Some tournaments allow late reg all the way into Day 2, where players jump in with just 25 big blinds — and many pros swear this is the optimal strategy.

From the operator's perspective, long late reg makes perfect sense. It opens the door to a larger player base. If a tournament kicks off at 6 p.m. and a player can’t get home from work until 8, a 3-hour late reg window gives them a shot to join.

And let’s not forget: tournament organizers take a fee for every single registration. In a $1,100 buy-in event, $100 of that goes straight to the house as rake. Turning players away once the cards are dealt? That’s just leaving money on the table — something no business wants to do.

Late registration isn’t just about rake or operator profits — it also caters to a certain type of player. For many recreational players, long days at the table aren’t appealing. Some just don’t want to grind for 10+ hours only to bust before the money. For them, late reg is a shortcut to get closer to the bubble.

Even legends like Doyle Brunson took advantage of it — his only WSOP 2018 appearance was in a tournament that allowed Day 2 registration, simply because he didn’t want to play for three straight days.

But what about you? Should you be registering late? Let’s break it down. There are both advantages and disadvantages to buy-in late — and as a player, it’s on you to decide which approach fits your style.

Here’s the trade-off: When you register late — even in the WSOP Main Event — you’re giving up early hands against weaker players who may not understand deep stack play. At the same time, you're starting with a shorter stack than average, and that puts you behind.

The blinds are already significant, and the early-stage cushion you would’ve had is long gone. Your stack just doesn’t go as far. If you like having room to maneuver, to three-bet light or float flops with speculative hands, showing up on time is clearly better. But that doesn’t mean late reg has no upside.

Consider this: While you’re waiting to register late, you might watch players punting off their stacks with questionable plays or bad beats. Sitting down with a full stack while others are clinging to life can feel like a huge advantage.

You can’t win the tournament in Level 1 — but you can lose it. And if rebuys aren’t allowed, surviving the early chaos can be valuable. It all comes down to self-awareness. Know your game. If you're a strong MTT player, confident in adjusting quickly and picking up reads fast, late reg might still be profitable. You just have to be ready to navigate the short stack minefield right from the start.

Here’s something that many casual players overlook: the real edge in tournaments often doesn't come from those deep-stacked early levels. Sure, you might grind six levels of perfect post-flop poker and build your stack by 20%. But a savvy late-registrant can achieve a similar gain just by picking up blinds a few times. For many pros, the early levels don’t offer enough upside to justify the time investment — especially when they feel their true edge shines later, under pressure, when the pay jumps matter.

The difference between amateurs and pros is often psychological. The pros are better equipped to navigate high-stakes situations. So while they give up some early advantages, they make up for it when it really counts.

ICM stands for Independent Chip Model — a way to calculate the real-world dollar value of your tournament stack. Early in a $1,000 buy-in event, your stack is worth roughly what you paid for it. But if you buy in late — after dozens of players have already busted — your stack is actually worth more.

Let’s say you're in a $10 Sit & Go with 10 players and 3 paid spots. Everyone’s equity starts at $10. Now imagine joining as the 11th player midway through, when five players are already gone and five others have doubled up. Even though you’re just now entering, your chip equity jumps by almost 10% — up to $10.87 — simply because there are fewer people left to beat.

Now scale that up. Suppose you're registering for a standard MTT. Thirty-three players entered. Eighteen are already out. You join just before late reg closes. Just by timing your entry, your equity increases by a massive 22% — without playing a single hand.

Of course, ICM gets trickier when fields are larger than two tables, but the takeaway is clear: in terms of pure chip value, late registration can offer hidden value — especially if you’re skilled enough to navigate short stacks and late-stage dynamics.

In our earlier example, we joined a tournament just before late registration closed — and saw an impressive 22% equity boost simply because many players had already busted. But once you scale beyond two tables, ICM math becomes so complex that even experts struggle to quantify the true value.

When it comes to enormous fields — like the WSOP Main Event — calculating the exact ICM edge of late registration would require a supercomputer. But based on observable patterns, we know this: late registering the Main Event is profitable.

The ICM benefits of late registration in tournaments:

However, there's a catch — a big one. If you're a skilled player, the real profit lies in playing from the start of Day 1. Why? Because early on, the field is soft. You're surrounded by amateurs playing deep-stacked poker — a format they're often not comfortable with. If you have an edge, that's where you apply pressure and build a stack.

That's not only frustrating but also expensive if it’s a live event. And in some formats, late registration is just plain bad strategy. The biggest mistake? Late-regging a bounty tournament. Since a large portion of the prize pool comes from knocking out other players, arriving late means you've missed tons of valuable bounty opportunities. This is why Phil Hellmuth faced backlash after selling pieces at a high markup in a bounty event he entered late — many felt his approach undervalued the lost EV from missed knockouts.

There’s one exception: the mystery bounty format. In these events, bounties aren’t live until Day 2. By then, about two-thirds of the field is gone, and bounty values are significantly higher — often surpassing the initial buy-in. Here, late registration can actually make strategic sense. The closer you are to Day 2, the better your shot at hitting one of those juicy mystery bounties.

Opinions on late registration vary widely among poker players. One of the most vocal critics is Mike Matusow, who has repeatedly called for an end to maximum late registration. In 2021, he targeted the WSOP Main Event, which now allows players to buy in two levels into Day 2 — a format he believes undermines the spirit of the tournament.

To put that in perspective: the money bubble typically bursts late on Day 3, meaning a max-late-reg player could potentially cash after only 1.5 days of play. Matusow went so far as to claim it’s his life mission to eliminate max late reg from tournament poker altogether.

His main argument? It unfairly benefits wealthier players, who can afford to skip the early stages and casually enter a $10K event after a large portion of the field has already been eliminated. According to him, this cheapens prestigious events that should test a player’s skill and stamina from start to finish.

In fact, Matusow noted that with Jungleman’s win in the $50K, at least six players in 2021 alone have taken down events after registering on Day 2 — a trend he believes reflects poorly on tournament poker as a whole.

And that’s the heart of the issue: optics. Like HUDs or unlimited re-entries, late registration doesn’t necessarily harm the integrity of the game. But if enough recreational players perceive it as unfair, that perception alone could justify rethinking its implementation.

That said, there’s no solid evidence that early registration is always better than buy-in late. Each approach comes with trade-offs — and late reg offers flexibility, especially for those who know how to navigate short-stack play or prefer to avoid deep early levels. So, what's the best answer?

Late registration isn’t inherently good or bad — it’s a tool. For some players, it offers strategic flexibility and potential ICM benefits. For others, it sacrifices valuable early edges against weaker opponents. The key is understanding your own strengths, the structure of the tournament, and what kind of stack dynamics you’re comfortable with.
