SB Open – All Stack Depths
Default preflop ranges for the SB Open spot in 6-Max MTT at every stack depth, from the RangerPro library.
The Small Blind acts last pre-flop but first post-flop. Opening ranges from SB must account for the Big Blind's positional advantage after the flop.
Opening (raise first in) sets the pace for the hand. Your open-raise range defines which hands are strong enough to voluntarily enter the pot and face potential 3-bets.
Default range at 100bb

As stacks get shorter, the SB Open 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 SB opening range sometimes wider than expected? expand_more
When folded to the SB, only the BB remains. This creates a heads-up dynamic where you can open wide, especially if the BB defends passively. At 100bb, the SB opens 145 hands (85.8%).
Should I raise or limp from the Small Blind? expand_more
In MTTs, raising is strongly preferred. Limping can be exploited by an aggressive BB who will raise you frequently. A raise puts you in the driver's seat despite your post-flop positional disadvantage.
How does SB vs BB dynamics change at short stacks? expand_more
At short stacks (15bb and below), SB strategy often becomes push-or-fold. The stack-to-pot ratio is too shallow for a raise-fold strategy, so you're either shoving your range or folding.
