"As your postflop skills increase, you should start playing a bit looser before the flop, opting to call raises and limp along a bit more often with the intention of attacking the pot with multiple postflop bets when it is clear your opponents have weak holdings. This will allow you to slowly grind up your stack with minimal risk. However, if you do not navigate tricky postflop situations well, you can easily spew off a ton of money. On the other hand, if you never get involved in tricky spots, you will never gain the experience required to excel."
