Building Your Preflop Foundation

What Building Your Preflop Foundation covers

Move from knowing what a range is to understanding how real preflop strategy is constructed.

Learn why position, ranges and stack depth determine which hands enter the pot.

Learning objectives

• Understand how position shapes which hands are profitable to play
• Reconstruct real MTT baseline opening strategies from every seat at 15bb-60bb
• See how stack depth, sizing, antes and rake reshape a preflop plan

Lessons in this module

First In

Knowing what to do when everyone folds to you is one of poker's most important skills.

What Makes a Hand Playable?

Equity, playability, blockers and nut potential all shape which hands belong in a range.

Stack Depth Changes Everything

The same position can call for a completely different strategy at 15bb, 25bb, 40bb and 60bb.

UTG Mastery

The tightest seat at the table — and the one that changes least with stack depth.

UTG+1 Mastery

Fairly linear — but the range actually narrows again at the deepest stacks.

UTG+2 Mastery

The last true early-position seat — and where the open-jam disappears for good.

Lojack Mastery

Plays like the Hijack, but tighter — the price of one extra player left to act.

Hijack Mastery

The widest true middle-position seat — and one where 25bb to 40bb barely changes anything.

Cutoff Mastery

Only two players left to act — and one of the very few seats that widens steadily with depth.

Button Mastery

No one can ever put the Button out of position — the widest non-blind opening range at the table.

Small Blind Mastery

Guaranteed to play out of position if called — and the only seat where limping is a real weapon.

Preflop Range Mastery Lab

Roughly 40 interleaved table decisions, boundary comparisons, stack-depth and position comparisons, and reconstructions — every position, every depth, in random order.
