chasing a draw

when is the right time to chase for a draw? (flush / Straight)

When you're getting the right price (pot odds) and/or when your implied odds are high (villain will pay you very well if you do hit)

for me it would be when i have a open ended staright draw or flush draw and getting good pot odds to make the call,if opponent raised preflop depending on his position,i can guess what hand ranges he might have hold,if my hand ranges off him hit on flop i would then see my position over him,if i am over him i could decide depend upon his act as i am having position over him, if i am first to act ,then i would normally bet 1/2 pot to confirm my hand ranges ,then act accordingly .. it all come down to information,ur position on table,table images etcc.. if i am short stack and if i my raise gonna put me pot commited after the flop ,its better to shove on the flop with correct odds and draw ,or fold ..

It all comes down to understanding outs and pot size. Outs are the number of cards that make your hand. In a flush draw with 4 to the blush you have 9 outs, an open ended straight draw has 8 outs and a combination flush/straight draw has 15 outs. Outs tell you your chance of making your hand. I use the rule of 4 and 2.

With 2 cards to come the percentage of the time you make your hand is the number of outs times 4. A flush draw completes ~36% of the time, a straight draw ~32% of the time and a combo flush/straight draw ~60% of the time. When there is only one card to come, it's half that. Knowing the approximate odds brings you to the pot.

If there is $10 in the pot and someone bets pot with you call with your last $10 if the odds of winning are are 33% or better (You have to put $10 in to win $20, the bet and the existing pot). With 2 to come you are a little better than that with all of the draws. It is a little more complicated if you have more cash to bet on the next card.

If you don't hit you'll face a bet on the turn and have to put more money in. Since you aren't guaranteed to see two cards you should use the 1 card to come calc and don't have the odds to call a pot size bet, but do have enough to call a 1/2 pot bet.

That's the basics. Lots of things to think about as stacks get deeper.

Very rarely. It's not often that you are getting the right price. But it can be worth it if you have compound draws.

Like:

You hold 5 4 clubs on the button. Villain raises UTG +1 to 3.25xBB, you figure you'll take a flop. Blinds fold.

Flop comes Ac, Kc, 7d

You have a flush draw, and a super flimsy backdoor straight we can essentially discount. It's safe to assume your 5 and 4 are not live outs at the moment. That gives you %18.7 (or something) to hit an immediate out, or what we'll call 1:4 card odds.

With 9BB in the pot, you only break even if the villain leads out for 3BB or less. Which is fairly uncommon. That means the villain would have to c-bet for less than the pre-flop raise. Doesn't happen a lot.

But then there's a lot more to it then strictly the math. Still, gotta at least know the math to figure what you're doing.

obviously when you have odds , but it's not always good to pursue a draw just taking calls, because it's easy to read the opponent your hand , I personally usually use semi- bluff using raises case I note that the opponent is unsafe in hand
