The Big Blind forces you to play a large number of hands, making it the most important position to learn if you want to instantly improve at poker. Look at some Big Blind tips based on Poker Academy’s Preflop Charts which you could purchase right now and start learning poker online.
Defending Big Blind. Don’t play every hand
When you are in a Blind vs Blind situation, it is very tempting to play every hand. However, you should understand your folding range to avoid losing money in the long run. As you can see below, in a 40 BB deep scenario, you are supposed to fold almost 35% of your range vs. a 3.5 SB open. The folding range typically includes off suited, disconnected hands with poor playability postflop.
Obligatory defenses vs. SB. Play your suited hands
Regardless of whether you have 20, 40, or 70 BB in a no ICM scenario, you must defend all of your suited hands against an SB raise. When you are 40 BB deep, you should generally use a calling strategy, but you can also make value raises with hands like ATs to AKs and occasionally use pure bluffs like T2s or 93s.
Things are different when it comes to defending your BB vs. SB limps. Technically, the larger your stack, the more suited hands you should raise. When you are 100 BB deep, your minimum raising range for suited hands includes 8s, Ax, and one-gappers like 42 and 53. As your stack becomes shallower, more suited hands become pure calls.

Sometimes you can jam. Even when you have 30bb
When the opponent raises 3.5x from the SB with 30 BB, you mostly call (more than 55% of the time). Raising and folding are also options, but there is a small percentage of hands you can sometimes use for ISO jams. As you can see below, some hands like AQ and AJ offsuit are good for going all-in, as you could be called by worse Ax hands or dominated hands like KQ, QJ, or even A5s. It is also strongly recommended to isolate with pocket pairs from 5s and below so you can make your opponents fold more often.
Be polarized. Learn how to play off suited hands
The offsuit portion of the Big Blind range against an SB limp is polarized. This means you mostly want to raise your best and worst hands. Holding hands like Q2o, 85o, and 72o unblocks part of the Small Blind’s limps, which they should fold against your aggression. You can see below how the SB should react when facing a BB 3.5x ISO raise (40 BB deep).
