BB vs Open UTG – All Stack Depths
Default preflop ranges for the BB vs Open UTG spot in 6-Max MTT at every stack depth, from the RangerPro library.
The Big Blind already has money invested and closes the pre-flop action. This creates wide defending ranges against opens, especially at deeper stacks where implied odds matter.
Facing an open raise, you must decide between calling, 3-betting, or folding. Your defending range depends on the opener's position — a UTG open demands more respect than a Button open.
Default range at 100bb

As stacks get shorter, the BB vs Open UTG range tightens. Speculative hands lose implied odds value and the range converges on premium holdings. The table above shows exactly how many hands are included at each depth.
help Frequently Asked Questions
Why is the BB defending range so wide? expand_more
The BB already has one big blind invested, getting a discount on calls. At 100bb, the BB defends with 108 hands (63.9%) because folding too often lets opponents profitably steal with any two cards.
Should I always call from the BB or sometimes 3-bet? expand_more
A mix of calling and 3-betting is optimal. 3-betting protects your range and builds pots with premium hands. Pure calling makes you predictable and lets the raiser realize their equity cheaply.
How do I adjust my BB defense against different positions? expand_more
Defend wider against late-position opens (CO, BTN) because their ranges are wider. Tighten up against UTG and HJ opens, which represent much stronger hands. The opener's position is the single most important factor.
