Honestly it depends on alot -- we can literally defend our BB to a 2x raise with literally any 2 cards -- that being said unless you are very comfortable in your skillet post flop - this approach will not be profitable. As bet sizes increase - our defending range decreases - this is where the term "condensed ranges" comes from. Effectively by fishy players opening 3x-4x in spots where they should be going 2x-2.2x they will cause players to condense their ranges and only call them with their stronger holdings -- so the same thing happens to us in the blinds - even a sizing as small as 2.5x makes a difference in what we defend vs a 2x raise.
Moving on - basically the earlier the PFR, the tighter we defend our BB - we also defend much tighter against more than 1 opponent since multiway pots are tricky and facing multiple ranges is not ideal.
Anyhow, vs. BTN sized to 2.2bb open we are defending somewhere around 65-70% of our range normally. We get even wider vs a SB raise, defending somewhere around 80% of our range. And as the raise comes from earlier positions around the table our defending range decreases slightly in theory. This is also where most people get the ranging wrong -- as the raises come from earlier positions at the table we start to drop off alot of our weaker offsuit broadway hands (Jx, Qx, and Kx) and such because the opening ranges from our villan would have better broadway holdings in their ranges - thus causing us to lose chips when we hit top pair on flops. Anyhow, so we drop those holdings off and continue to defend lots if low and middling connected hands, suited hands, pocket pairs and Ax - with the same concept of our Ax hands in mind that we don't get over invested when we hit top pr vs a strong Ax heavy range. We defend the lower and middling connector cards because EP villans don't have many of those in their ranges.
There's alot of subject matter floating around on this subject. Hopefully my little bit makes sense and is helpful.
You're right, there seems to be a lot of things to take into considerations. Your answers are really helpful, though I admit there are some things that are new to me. Thing is I'm not good at using maths at poker, but I'm looking to get good at it. Any recommendations about where to start?
Personally, I don't see the need to defend my big blind very often! Of course, a lot depends on the players sitting on my right, but defending with any 2 cards is a negative idea for me!
You need to protect the blinds when the strength of your hand allows you to do so. Obviously, if you protect blinds with junk, then more often than not you will get losses and frustrations.
*sigh*
One more time....if you play your actual hole cards...yes 72o doesn't win pots very often - but if you understand board textures and ranges enough - then you can take that garbage, and ram it down your villans throat who is over cbetting the flop and get them to fold.
Playing well post flop is key - but if you ONLY wait for stronger holdings to defend your blinds with - then you will be exploitable!! How so? Simple...if you're that tight, when you finally do defend your blind I simply won't give you any action, and when I do, it will only be with the strongest of my holdings.
Nitty players are easier to play against than any others on the table - because they play their holdings face up. They call when they have it, fold when they don't and rarely ever raise as a bluff, and if it is at all its a semi bluff.
I'm not advocating for every player to defend 100% of their holdings - im simply saying, one of the most common problems with players and their blinds is people under defend and they over fold....and here we are with people chiming in on only playing the better parts of your holdings - only providing my point! This makes you all much easier to play against.
Sharpen up your post flop skills - begin to understand ranges and board textures - then learn which of those you should be check-raising and with what holdings, which of those you should be check-calling and with what holdings, which of those you can donk lead, etc.
Simply defending your BB with 78o - going to a flop of 246 or 64J and just check folding to a cbet is costing you money. If you recognize the smaller card textures hit your range more than they do your villans - then you can check-raise, give yourself a chance to win the pot, and move on. Why check raise 78o on a flop of 64J?
Because you have all the suited Jx combos, you have 44d and 66s, you have all the two pair combos - you also have open ender draws and such - not to mention like I said earlier, villans are over cbetting - so when you check raise here, that should polarize them to only continuing with a J or better - the end result is, you just get tons of folds.
So one more time to recap, defending your blinds doesn't always mean it's all cut and dry, black and white - you're going to have to play post flop well too. If you're just playing ABC poker...than exploiting you is as easy as 123
*sigh*
..... everyone has the right to play as he sees fit.
At least my bankroll is growing because I just don't play with junk.
I often find myself defending my blinds too much, putting me in tough spots.
So my question is: when do you need to defend your blinds? And how to do it effectively?
Everyone definitely has the right to play however they so chose. Choosing to ignore solid proven strategy is also an individuals personal choice.
You and others are simply missing the bigger picture - im not advocating for everyone to just jump into defending 80% of their range...but if you become more familiar with ranging and post flop plays - you will see more and more the cards in your hands don't even matter anymore.. Winning pots you are not supposed to win and playing well post flop will net you way more money than ABC poker ever will. Thanks for the reply, I've said my peace here, I don't think I have anything further to offer this thread.
