Defending Your Blinds

Every orbit, you're forced to post the small blind and big blind — dead money that goes into the pot before you see your cards. If you fold too often from the blinds, opponents can raise relentlessly and print money against you. Defending your blinds at the right frequency prevents this exploitation and ensures you're not hemorrhaging chips.

However, blind defense comes with a built-in disadvantage: you'll be out of position for the entire hand post-flop. This means you need to be strategic about which hands you defend with and how you choose to defend — calling, 3-betting, or folding. The goal isn't to defend every hand; it's to defend enough to make your opponent's steals unprofitable.

Modern poker theory suggests the big blind should defend roughly 40-55% of hands against a button open, depending on the raise size and your opponent's tendencies. The small blind should defend less frequently (around 20-30%) because you're not closing the action and face additional risk from the big blind behind you.

Your defense frequency should shift based on several factors. The most important is your opponent's opening position. Defend wider against button and cutoff opens (their ranges are wide) and tighter against UTG and HJ opens (their ranges are strong). Defending 87 suited against a button open is reasonable; against a UTG open, it's usually a fold.

Raise sizing also matters. Against a min-raise (2x), you're getting great pot odds and should defend wider. Against a 3x raise, you need a stronger hand to continue. Stack depth plays a role too — deeper stacks favor calling with speculative hands that can win big pots when they hit.

3-betting from the blinds is essential because it partially compensates for your positional disadvantage. When you 3-bet, you build a bigger pot where your range advantage (stronger average hand) helps offset the positional disadvantage. You also gain the initiative — when you're the aggressor, opponents check to you more often post-flop, giving you control.

From the big blind, split your continuing range into calls and 3-bets. Strong hands like QQ+, AK, and AQs should almost always 3-bet. Add suited wheel aces (A2s-A5s) and suited connectors as bluff 3-bets. Hands in the middle — like KJs, QTs, and medium pairs — are better as calls because they play well post-flop but don't benefit as much from bloating the pot.

From the small blind, 3-betting becomes even more important because you have the worst position at the table (you act first on every street, even before the big blind). Many strong players adopt a "3-bet or fold" strategy from the small blind, rarely flat calling. Calling from the small blind invites a squeeze from the big blind and guarantees poor position in a multiway pot.

When you defend your blind by calling, you'll play the rest of the hand out of position. This is inherently disadvantageous, so you need to adapt your post-flop strategy. The key adjustment is to use a check-raise and donk-bet strategy on boards that favor your range.

As the big blind caller, your range contains many hands the opener doesn't have — hands like 74s, 96s, and 52s that would have been folded from other positions. On low, connected boards (like 7-6-3 or 8-5-4), your range has more two-pairs, sets, and straights than the opener's range. These are good spots to check-raise for value and as bluffs.
