Tip # 7 of 52, When players have already entered the pot for one bet, there are some playable hands that are worth a call but not a raise, because they need to improve to win the pot.
As in Tip 6, some hands are profitable to play, but Don't have to be played for a raise. This may seem to contradict the tight-aggressive style being preached here. However, this is not necessarily the case. When you make a raise in hold'em, you should have a clear objective. Essentially, raises are made for one of two reasons. The first is to eliminate players, and the second is to increase the size of the pot due to the strength of your hand.
When players have already called the initial bet, your raise will not accomplish the first objective. It may cut down on the number of additional players to enter the hand, but if several players have already called, you will still be facing a multiway situation. Thus, should you choose to raise, you are not doing it for the purpose of eliminating players.
So, with players already in the pot, the main reason for you to raise is to increase the size of the pot due to the strength of your hand. Few hands are strong enough to merit a raise here. These hands are summarized in Tip 6.
Calling is correct with hands that play well against several players. Primarily, these hands include medium pairs from fives to tens, and big suited cards such as K-Q or A-J. The reason why you Don't raise with these hands is that they need improvement to win. For the big suited cards, you need to flop a pair, straight draw, or flush draw to continue with the hand. For the pairs, you need to flop a set (three of a kind), although flops such as 2-2-5 are frequently good enough for a hand such as 9-9 when four or five players are in the pot. So, by just calling preflop, you are able to make a minimal initial investment, allowing you to release your hand quickly and painlessly when the flop misses you. However, should you catch a nice flop, you can now go into an offensive mode. Essentially, with these types of hands in multiway situations, you are saving your tight-aggressive play until after the flop, when you have more information.
Sometimes you are sitting in late position holding a decent hand when five or more players have limped in. How should these family pots (those with multiple players) affect your starting requirements? First, remember that with so many participants, it will likely require a better than normal hand to end up winning the pot. In two- or three-way pots, hands such as top pair (one of your cards matching the highest card on the board, such as A-9 and a flop of 9-4-2) tend to get the job done. However, top pair (even two aces) will usually not be enough against more than five opponents.
So, you should look to play hands that have the potential to develop beyond just one pair. Hands such as A-T offsuit are virtually worthless in these situations, as they contain little straight or flush potential. Instead, good hands include any pair and big connecting suited cards. With a pair, you should win a nice pot if you flop a set, as one of your many opponents will likely pay you off when he holds top pair. The hand T-9 suited is definitely playable here, as it possesses the versatility of turning into a straight or a flush. However, with a hand such as this, you can't get too excited when you flop a pair, if several players are involved. You will likely be either outkicked* or outdrawn, as a middle pair is extremely vulnerable.
