Defending your large blind appropriately is a giant a part of a profitable event technique. Within the GTO world, dealing with a regular button open and enjoying 40 large blinds efficient, you can be defending over 70%, with round 61% of your arms performed as a name preflop.
This implies you’ll should cope with many several types of flops, enjoying out of place. The flop texture will largely outline how you need to play after checking and dealing with a c-bet from the button opponent.
On this article, we’ll cowl the GTO technique for the large blind protection in opposition to the button continuation wager on dry boards, specializing in situations with 40 large blinds efficient.
Moreover, we’ll tackle conditions when enjoying barely deeper (60 large blinds) and when navigating a comparatively brief stack (25 large blinds).
Earlier than we dig into particular examples of consultant boards, listed here are just a few fundamental takeaways to information you thru the article:
We’re persevering with about 40% on dry ace-high flops
Test-raise on ace-high dry boards solely when dealing with a small c-bet
We’re defending 60% on dry high-card flops with frequent raises
Defend in opposition to a c-bet about 50% on low-card disjointed flops, check-raising a few quarter of the time
Tip #1: Name Round 40% & Solely Increase Going through a Small Guess on Ace-Excessive Dry Flops
On ace-high dry flops, such because the A♠9♥5&golf equipment;, the button participant is meant to continuation wager 100% of the time. These kinds of textures favor the raiser and don’t coordinate effectively with the arms in our calling vary.
What’s attention-grabbing is that the button needs to be utilizing three completely different wager sizes:
Small (24% of the pot) – round 62% of the time
Large – (67% of the pot) – round 21%
Over-bet (100% of the pot) for the remaining
We is not going to go into how the button’s c-betting vary breaks down throughout these completely different choices, as that’s a subject for a unique article, however the dimension they select will largely have an effect on our large blind protection technique.
Towards an over-bet, we’re calling round 35% and haven’t any raises (besides 9-5 and AT particularly). Our calling vary consists of all pairs (folding the weakest backside pairs a number of the time) and gutshot straight attracts.
Going through a giant (67%) wager, our calling vary will increase to 40% and we’re elevating about 3%. Slight changes to our technique vs. the one we use in opposition to an overbet are primarily that we are actually all the time calling with all backside pairs and likewise elevating at a small frequency (15% or so) with our gutshots.
Towards a small wager – we’re persevering with at 57%, which incorporates over 14% elevating. Our strongest top-pair combos, corresponding to AT – A7 change into good increase candidates dealing with a small wager, whereas we are able to now additionally increase extra liberally with gutshots and actually have a choice of bluffs with no showdown and just some backdoor potential (like T7s, 74s, and 63s)

Not surprisingly, the technique at 60 large blinds efficient isn’t a lot completely different. Maybe essentially the most notable distinction is when dealing with a small wager. In these conditions, we’re calling round 50% and solely elevating about 3%, as with deeper stacks, we aren’t as prepared to decide to the pot with a few of our marginal sturdy holdings like A8 and A7.

At 25 large blinds efficient, our large blind technique in opposition to a c-bet is kind of a bit completely different and moderately easy. The button is simply speculated to make the most of the 60% pot sizing, and dealing with that wager, we’re calling with 15% of our vary and folding the remaining.

The rationale there are not any 3-bet jams obtainable is that we lack sturdy arms on this texture that we wouldn’t 3-bet earlier than the flop.
Tip #2: Defend at 60% on Dry Excessive-Card Flops With Frequent Raises
In contrast to ace-high dry flops, which, as you may see, are fairly difficult to play, dry flops that includes a excessive card are pretty easy. On a board like Ok♠8♥4♦, the button will make the most of the small sizing of 24% of the pot just about completely, and in opposition to that sizing, we’re persevering with with 60% of our vary:

As you may see, we’ve fairly a giant elevating vary in these spots, because the arms we defend with from the large blind will coordinate significantly better with high-card boards.
The arms we’ll be check-raising with embody:
Two pair combos (K8, K4)
Virtually all high pair arms, at the least at some frequency
Center pairs + backdoors
Gutshots
The arms that we’ll be calling with completely are largely backside pairs and the weakest of our center pairs, combining that with a number of the weakest high pair holdings for steadiness.
On the stack depth of 60 large blinds, we see the same old adjustment, the place our protection vary strikes up barely (to 65% general), however we’re check-raising much less continuously. At this stack depth, arms like middling high pairs (K7, K6) transfer primarily to the decision bucket, and we’re additionally including some calls with our comparatively sturdy high pairs like KT and KJ.
When enjoying 25 large blinds efficient, the button will make the most of the 25% pot sizing completely once they resolve to c-bet (which is about 90% of the time). Towards that wager, our technique is just about similar to the one we use at 40 large blinds, persevering with at 60% with nearly 25% check-raise.
Tip 3: Defend Simply Below Half the Time on Low Disconnected Flops
On low-card dry flops like 9♠5♥2&golf equipment;, you’ll principally face a big, pot-sized continuation wager. Regardless of the large sizing, we’re nonetheless persevering with with round 45% of the vary, enjoying it primarily as a name, with about 20% raises:

As you may see, we’re persevering with with all of the arms that hit the board, together with all pairs. One of the best of these arms, we’re enjoying as raises.
We’re additionally calling and infrequently elevating with a few of our gutshot attracts, however these dry boards don’t lend themselves to many sturdy attracts, which is why these raises make up solely a small a part of our persevering with vary.
When enjoying 60 large blinds deep, our elevating share decreases barely, whereas our calling share will increase barely. Our general persevering with vary stays just about the identical, although, with none main variations meriting an in depth dialogue.
At 25 large blinds efficient, the button participant will principally make the most of the 60% sizing (as a consequence of shallower stacks). Going through that wager, we must always proceed simply over half of the time (53%), check-raising a few quarter of the time.
The general technique is kind of much like that we make the most of at 40 large blinds, however barely wider as sure marginal arms change into extra playable because the SPR decreases:
