As tournament In some instances, players might feel an urge to act sooner than preferred at the poker table, perhaps due to a looming threat from increasing blind levels. poker tournament While we may not be in an ideal scenario, the rapid escalation of blinds prompts us to seize some opportunity now, or we risk becoming severely short-stacked.
If we could play without the worry of depleting our chip stack, we would likely opt to wait for a more advantageous situation instead of settling for a marginal one.
However, tournament poker doesn’t allow us that luxury. Unlike cash games, we need to factor in our tournament life during each hand we play.
The ideal choice in a tournament setting always considers the current dynamics, including our chip stack and the ever-increasing blinds. effective stacks Our focus needs to be on how our chip stack compares with the blinds, as this will inform our overall strategy. If only we could access a simple calculation for this... blinds Fortunately, we can! This is where the concept of 'M-ratio,' or simply 'M,' comes into play.
“M” quantifies the number of rounds we can expect to survive based on our current chip stack juxtaposed with blind and ante sizes.

M Ratio – The Calculation
Let's calculate our M value in a straightforward tournament scenario.
Question: We have a stack of $1,000. The small blind (SB) is $10, the big blind (BB) is $20, and the antes are $1 while playing 10-handed. What does our M value equal?
To find this out, we can plug the relevant figures into our formula. The term '
' refers to the total antes incurred during a round and can be computed as follows: Antes We should consider the total ante cost for the entire orbit, not just the single ante amount. For example, if the ante is $1 and there are 10 players, our total ante cost per orbit amounts to $10.
Ante-price * number of players
Having an M of 25 means we can ideally last for 25 orbits, provided the hand structure remains unchanged . However, this isn’t realistic, as the next blind level will come into play soon, reducing our M.
M = $1000 / ($10 + $20 + $10)
M = $1000 / $40
M = 25
Thus, holding an M of 25 in a standard tournament is not equivalent to having the same M in a fast-paced ultra-turbo tournament, as we must consider the blind structure.
Calculating our M value gives us some insight, but on its own, it doesn't provide a complete picture. How can we effectively utilize our M value to shape our strategic approach?
Using M Value to Make Decisions
In his book Harrington on Hold'em, Dan Harrington offers some rough guidelines on how to assess and leverage our M value. He identifies various ranges where M values fit and outlines our corresponding strategic approaches. strategy in a tournament setting ?
M greater than 20 – The Green Zone – When our M exceeds 20, we generally have the flexibility to adopt either a conservative or aggressive style of play. We can afford to be patient for strong hands while also experimenting with riskier, speculative plays since our chip stack provides enough buffer for potential losses.
M between 10 and 20 – The Yellow Zone – As we enter the Yellow Zone, the pressure mounts, urging us to find viable spots to engage in play. Many of the speculative hands that were playable in the Green Zone may now become less feasible due to tighter effective stacks.
M between 6 and 10 – The Orange Zone – Here, the stakes are raised, and we must be cautious to not squander any chips. Cold-calling is risky, and it's crucial to be the first player to engage in the pot whenever possible. By opening the action with a raise, we enhance our chances due to increased fold-equity. poker hands M between 1 and 6 – The Red Zone – At this point, we've reached the push/fold phase of tournament play, reducing our options to either going all-in or folding.
M under 1 – Dead Zone – We want to steer clear of this zone, as nearly every aspect becomes a game of chance. It’s crucial that our tournament journey is driven by skill, not luck. In this situation, we should look for a chance to act first and potentially go all-in in hopes of a fortunate turnaround. Although numerous players have miraculously triumphed from the dead zone, typically, this signifies the end of our tournament.
M calculations apply across tables of any size, with the number of remaining orbits being minimally impacted by the number of contestants. Some variation occurs due to alterations in ante payments, slightly extending our orbit count if tables become shorter. (Short-handed tables usually emerge only as we approach the final table, with the majority of tournaments having full-capacity players).
However, does an M of 5 on a 5-handed table equate to having an M of 5 on a 10-handed table? Not exactly. Although the orbit count may not vary significantly, the number of opportunities to engage in hands doubles on a 10-handed setup. shove To navigate this situation, we utilize what's known as effective M, which incorporates the quicker decision-making required when tables shrink in size. The standard M metric will be referred to as simple M.
Adjustment for Shorthanded Tables
The relationship between them can be expressed as follows:
Effectively, we are calculating a percentage of Simple M based on how 'full' the table remains, assuming a full table consists of 10 players. For example, a player with a simple M of 10 on a 5-handed table would have an effective M of 5.
Now, let's pose a question that ties all these concepts together.
Question: If our effective stacks are $1,000, with blinds at $20/40 and antes of $2, while playing with 5 players, what are our simple M and effective M values?
With any luck, you can figure this out independently. Here’s the calculation:
So moving forward, let's commit to paying attention to our M-ratio while we’re at the tables. Use it as a tool to shape your game plan at each stage of the tournament.
