here, to add a bit to this slowplay/not slowplay thing, this is a post from 2+2 written by a brilliant player named whitelime. he's even better than kathy liebert imo. i recommend everybody read this:
"Preflop slowplaying is bad, but postflop slowplaying is usually much worse.
I call the following "The Idiot's Monster"
Call Preflop with a drawing hand (pocket pair, suited connector)
Call raiser's flop bet when you hit your monster.
Raise the turn small (whether it's minraise or raise f/ $200 to $500).
Value bet the river.
I'm not saying to get rid of this line completely, however, pick your spots. Against most thinking players, you will not take their stack this way against an overpair. However, against some loose calling station whose entire thought process is "he bets more so he has a better hand", use this line (raising the flop is still superior) and value bet him into submission. He will never fold his TPGK.
Reasons slowplaying is bad:
1) Fastplaying is deceptive, slowplaying is not (against thinking players). You heard right. Because the overwhelming majority of players online slowplay their very strong hands, most thinking players will never see what hit them when you fastplay yours.
2) Fastplaying builds pots. This one should be obvious. You don't want streets checked when you have a very strong hand. You want the maximum amount going in on every street. When you flop a set and sense that your opponent has an overpair, pound him. Don't plan on taking half his stack. Go for it all. He probably isn't folding unless...
3) a scare card hits. I'm going to use a simple example to illustrate this point. You have 77 OOP against a preflop raiser. The flop comes T74 with a heart flush draw. You check call the flop. Think about how many turn cards could potentially kill your action. Any heart, T, J,6,3 could result in your opponent not willing to go to the felt with his overpair. Check-raising and leading out are both acceptable options. Check-calling is pretty bad.
Here is another example from a hand that I played recently:
No-Limit Hold'em, $ BB (6 max, 6 handed) converter
Preflop: Hero is UTG with 6, 5. SB posts a blind of $5.
Hero raises to $35, 3 folds, SB (poster) calls $30, BB calls $25.
Flop: ($105) K, 6, 6 (3 players)
SB checks, BB checks, Hero bets $70, SB calls $70, BB folds.
Turn: ($245) 6 (2 players)
SB checks, Hero bets $175, SB calls $175.
River: ($595) A (2 players)
SB checks, Hero ???
So many players will check the turn. Checking the turn is 100% wrong. It allows your opponent to play a small pot in a hand where he is either way ahead or way behind. Betting it also disguises your hand and most probably stacks Villain if he holds Kx. However, I forgot that an A could hit the river and potentially kill my action. The correct play in this situation is not only to bet the turn, but to bet all-in. This assures that you disguise your quads, get 95%+'s opponent's stacks all-in with Kx, and prevent a scare card (Ace) from killing your action on the river. This example illustrates how much can go wrong when you try to slowplay.
4) Your opponent doesn't bet! In the previous 77 example, I stated that check-raising and leading are both good options. The reason check-raising is equally good is because your opponent will often make a continuation bet when he misses which you would not gain if you lead. However, you should be wary of the fact that any time you check intending to trap, your opponent may check also."
