SB vs 4-Bet CO – All Stack Depths
Default preflop ranges for the SB vs 4-Bet CO 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.
A 4-bet pot is high-stakes territory. Your continue range is typically very narrow — premium pairs and select blockers. At shallow stacks, this often becomes an all-in decision.
