Deep Stack Opening Strategy (100bb)

Deep stack poker at 100bb is where the full range library comes to life. With 100 big blinds behind, every open-raise, 3-bet, and postflop decision has room for nuance. The ranges you use at this depth are the widest you will play at each position, and understanding them is the foundation for everything else. At 100bb, position-based opening ranges in a 6-Max MTT look roughly like this: UTG opens 15-18%%, HJ opens 19-22%%, CO opens 27-32%%, BTN opens 45-52%%, and SB opens 40-50%% when folded to. These percentages reflect the core principle that each additional position toward the Button adds hands to your range because there are fewer opponents behind and more positional equity to capture. The defining feature of deep stack play is implied odds. When you open a hand like 65s from the Cutoff at 100bb, you are not expecting to win immediately. You are investing a small raise with the potential to win a very large pot when you flop a straight, flush, or two pair. The ratio of what you can win to what you risk is enormous at 100bb, which is why suited connectors, small pairs, and suited aces flood the late-position ranges. RangerPro's range library shows this clearly. Compare the BTN range at 100bb to the BTN range at 25bb. At 100bb, you see hands like 54s, 86s, Q5s, and K7s lighting up the matrix. At 25bb, many of these hands disappear because the stacks are too shallow to realize their implied odds. Speculative hands at deep stacks include small pocket pairs (22-66) for set mining, suited connectors (54s-JTs) for straights and flushes, and suited aces (A2s-A9s) for nut flush draws. These hands share a common trait: they are cheap to play preflop and can make very strong hands postflop that extract maximum value from opponents. Postflop play at 100bb rewards patience and planning. Multi-street thinking becomes essential. When you flop a draw, you have room to call a bet on the flop, see the turn, and still have stack depth for a meaningful river decision. At shorter stacks, this luxury disappears, which is why deep stack poker is considered the most skill-intensive format. One strategic consideration at 100bb is 3-bet pot management. When you face a 3-bet at deep stacks, calling in position is often better than 4-betting because you preserve your stack and keep the pot manageable. Hands like JJ, TT, AQs, and suited broadways are often calls rather than 4-bets when deep, especially from late position. Tournament context matters too. Early in an MTT when stacks are deep and antes are small, the emphasis is on preserving chips and exploiting postflop skill edges rather than accumulating through aggression. The wide ranges at 100bb are designed for this environment, enabling you to see many flops cheaply and capitalize on strong hands.
