It's a bad idea to raise very often from the big blind.
When you would be raising from the bigs blinds, you would be doing so for one reason only: to get more 
money into the pot. You wouldn’t reduce poker players, as everyone who would have called one bet would surely call another. Also, you would be out of position throughout the play of the hand, which would undo some of your hand’s merit, because you wouldn’t be able to bet as many decent hands for value* from early position.
Consequently, it would probably be best to raise only with absolute best hands from the big blind. Against numerous limpers, only a pair of aces and a pair of kings would be truly raising hands. While it would be okay to raise with an ace and king suited, you must be prepared to check and fold if you weren’t to flop either a pair or a flush draw.
Against only one or two limpers, you could raise with a few extra hands, such as a pair of queens, pair of jacks, and an ace and king. The reason for this would be that with only a few poker rivals, your big pair would be more likely to hold up if one overcard* were to flop, and your raise would give you the lead in the pot. For instance, suppose you were to have a pair of queens in a three-way pot, and you were to opt not to raise. Now, the flop was a king, a nine, and a seven.
If you were to check, the next poker player would be likely to bet irrespective of whether he were to have a king, as he would be trying to win the pot based on the weakness implied by your check. You would now be in a position of indecision, which could have been avoided were you to raise preflop and then bet on the flop.
The same would go for raising with an ace and king in a three-way pot. If you were to have passed your big blind option and seen a flop of a two, a seven and an eight, your initial tendency would most likely be to check. By raising before the flop, though, you would have built a pot worth taking a stab at with a bet. If your poker rivals wouldn’t flop a pair, they would be hard-pressed to call.
Advocating not to raise with a pair of queens from the big blind when several poker players were to have limped in might appear to oppose the advice given in Tip thirteen about getting money into the pot with the best hand whenever possible, but this would not necessarily be so. All you would be doing is delaying the moment at which you would choose to increase your involvement.
With four of five limpers, it would be fairly safe to assume that one poker rival would be holding flops before deciding if you would wish to make a major commitment to this pot? After all, you would not be in a position to protect your hand, as all the ace and x and king and ten hands would already be in, and they would see the flop.
Now, if the flop would bring overcards, you could check and attempt to review if your hand would be beaten based on the action after you. Then again, if you were to catch a nice flop such as a two, a four, and a ten, you would be in a position to take your poker rivals by surprise. You could either bet out or go for a check-raise, but either way you might win more bets because your rivals would have miscalculated the strength of your hand due to your failure to raise preflop. So, you would have to be able to recover those bets that would have been in the pot if you had raised, and you could save money those times your pair would be outdrawn by overcards on the flop. When you were to have an occasion to play a poker hand in a manner that would limit your losses but not your wins, you would have to benefit from it.
Call more raises on the big blind than any other position.
If calling a single raise, you would always get a price of at least three to one on the big blind. 
The slimmest scenario would be when everyone would fold to the small blind, and he was to raise. More naturally, however, you would get a price of seven to one or better to call. Consequently, several other poker hands would become playable.
When deciding if your big blind hand would be worth defending, you would have to first pay attention to who had raised the pot, and from what position. You would be inclined to play tighter when the raise would be from an earlier position, or when a solid poker player was to raise.
You could be more moderate in your playing standards against loose or late-position raisers. For instance, you would have to fold an ace and eight suited against an early position raiser, but this hand would positively worth a play when the raise would be from late position.
Next, you should consider how many poker players would be in the pot. The more players, the better your odds would be. In multiway pots, some hands would fare better than others. You would have to try to defend more with hands that would have the potential to develop to better than one pair, since one pair often wouldn’t get the money when several poker players would be competing for the pot. These would include any pocket pair and medium to large suited connectors (seven and eight or better).
Simply having big cards in your poker hand wouldn’t justify a call in a multiway pot. The reason for this would be that it would be too easy to flop a pair and still lose, either to a bigger kicker or to two pair or a better hand. For instance, suppose you were to call a raise in a five-way pot with a king and jack offsuit. (If suited, you would have to call.) Now, the flop would come jack, nine and six. If the preflop raiser was to have a genuine hand, you might have already been beat.
Also, there would be three other poker players to contend with here, one of which could have an ace and jack, a pair of nines or a pair of sixes. Another hand that could be out would be a queen and a ten, a hand that would pose a serious threat to drawing out on your holding. All in all, a hand like a king and jack would be highly likely to end up in second place in a multiway race, which would be a costly proposition in holdem poker.
You should compare this to calling a raise with a pair of deuces. Although the flop would be much more likely to bring improvement if you were holding a king and a jack, the problem would be that the improvement could either not be enough, or could even help your opponents furthermore. With the deuces, though, you would have a pretty good idea of where you were to stand. If a deuce were to flop (which would happen slightly more than one time in nine), you would be in the driver’s seat.
This would have to be all the improvement you would need to win the pot, in spite of of how many poker players would be in. Therefore, you could play the hand very aggressively. Any poker player with top pair would likely call you down, and the more poker players that would be in the hand, the more likely it would be that someone would have flopped top pair.
