In most games of Hold 'em poker, the big blind (BB) is a full-sized bet for the first round of play. For example, in a $10/$20 game, the BB is $10, which basically means you only have to check in order to see a flop. No matter how bad your cards are (yes, even the proverbial "worst hand" of 7-2o), you should never fold a big blind hand in an unraised pot, because lightening does strike at times and you're already commited to the $$$ anyway. Of course, you may raise or reraise if you wish and we'll talk about that in just a bit.
However, the most important decision for a player in the BB is usually whether or not to call a raise (or two or three) and/or re-raise. A lot of players feel they must "protect" their blind bet from others who would steal it, so they automatically call any raise even though they may have that 7-2o as pocket cards. And don't kid yourself; it's very worthwhile to try and steal the blinds, especially when you consider that the expected value (EV) for a hand in a somewhat "loose" $10/$20 Hold 'em game is about $1, maybe $1.25. So, let's say a player on the button, who bets in front of the blinds pre-flop, has a decent, though not great hand like A-6s and s/he has noticed that the players in the blinds usually fold to a raise. If everyone else has folded up to this point, the player on the button (the "acting" dealer for this hand) should raise with the idea of stealing the blinds. Unfortunately, such a tactic won't work every time, so the expected value of such a play is somewhat less than the $15 in the blinds ($5 in the small blind and $10 in the big blind), but whatever the EV is, it's more than $1 and is undoubtedly many times higher than the EV for A-6s played all the way through from the button. Even if our semi-bluffer has to play out the hand, s/he's not sitting dead in the water with cards like A-6s, so the pot can still be won, even if one or another (or both) of the blinds call the raise. But we'll talk more about that when I discuss playing from the button in a future lesson.
Let's get back to our hand in the big blind. Most of the time all we have to do is check the hand and we'll see the flop. But what if the bet has been raised from the button? Or from the first bettor ("under the gun") or a player a little further along? Should we automatically call the raise? Of course, the answer is a resounding "no". Like most other situations in poker, what you should do depends primarily upon what cards you hold. You've already made one bet and those $$$ are gone if you fold, yet you have to remember that for the rest of the hand you'll be betting first, so you still need some decent cards to call one raise, let alone two or more. Then again, with the right cards, you can not only call several raises, but actually reraise and start building a "monster" pot. But monster pots are won by monster hands, so let's not get ahead of ourselves here. Because of the unique status of the big blind bet, I'm going to give you a separate list of minimum starting hands to use when you're in that position. As you know from Lesson 3, most hands that you'll get aren't playable at all, but because we've already made a full bet in the big blind, it's okay to loosen up a bit when a raise has been made in front of us.
Like all of the other starting hands, these have been determined through mathematical analysis (mostly simulations) on the Turbo Texas Hold 'em software that I've talked about before. There are no guesses, no "gut feelings" or any other voodoo involved here; either a hand is profitable or it isn't. If it isn't profitable, you won't find it in this list. In fact, I may have been a little too tight, because trying to hit the averages for something like this isn't easy. But if you'll go with these hands, I think you'll like your long-term results, so at least give it a try. As I've discussed before, the list of hands I'm going to present here will eventually be a part of my Hold 'em Poker Basic Strategy Matrix, which we're building layer by layer.
