Making decision when the clock is on you.

I find myself always running short on time during some tough decision.

1)my big hands are being reraised
2)A draw heavy flop came while I am holding a playable hand
3)when people raise me all in at the river with very little early betting.
4)when the possible scary card show up, i have to back track to all the prior betting arounds.

please tell me what is the first thing that you would call back or pay attention to when the above sitiuation happens?

for example should i think of the post flop betting first, the way the player have been betting or if i have the correct odd to continue?
So i can get my priority straight.

PS: i will only have 20 seconds party 25NL

Keep a running dialogue of the entire hand in your head as it progresses. Each bet means something. Use all of this information when you get to the point where you have to make a decision.

While you're not playing a hand you should be watching other people's betting patterns. Try to put people on hands. If there is a showdown try to figure out why people bet the way they did. In future hands against these players you can use this against them, because most people have similar betting patterns that they follow.

Watching the table will help you out later even if you've never played a single hand against a person. You'll start making moves on instincts alone. Sub-consciously you'll be thinking, "Okay, I've seen a guy bet like this before. He has 'x,' that means I should bet/check/fold." With experience this will get easier to do.

UG is right, you should always watch what is going on. I can’t do that however. Can’t is too strong…more like I don’t have it mastered yet.

Here is how I deal with it.
First, your instinct will be to call. WRONG. Your instinct should default to fold then look for reasons you might call. Look at the board, did the last card complete a straight or flush? Next look at the whole board and fit him into a hand that might make sense for his betting. Replay his bets, calls, raises against the hands you are fitting him on. Use up ALL your time. With practice it gets easier and faster.

Aok can probably say this better, but keep your decisions as simple as possible, especially if multitabling. PF at least you should know probably 90% of the time what you're going to do with any particular hand in any particular position with the given action. Simplifying your PF play will make post flop that much easier. That in turn makes it easier to play more than one table at a time.

Most hands you fold. Some hands you might limp in EP you'll raise in LP. Some hands you raise MP you fold LP to a raise. Have a plan as to what hands you will play, where you play them, and for how much. Much of this is work you should have done before you ever sit down at a table.

By having a plan before you sit down, you will come accross fewer situations where you run out of time. This is by no means the only consideration, but it can give you a solid basis for your decisions.
