It folds to you on the button with T♠9♠ after a middle-position raise.

Opener makes it 600 (3 BB); you hold T♠9♠ on the button. Best?

WhyCall. In position with a suited connector, you keep the pot flexible and set up to play big draws aggressively.
What happensYou call; the blinds fold.  Pot: 1,500 (7.5 BB).

Flop: J♠ 8♠ 2♦ - you flop a flush draw and an open-ended straight draw: fifteen outs. He bets 1,000.

Fifteen outs - about 54% by the river. He bets. Best?

WhyRaise. With fifteen outs you're roughly 54% by the river - an actual favorite over a single made pair. So you don't just call; you raise, combining fold equity with the best draw. A monster combo draw plays like a made hand.
What happensYou raise to 3,200; he shoves with an overpair.  Pot is now for stacks.

He jams all-in with what looks like an overpair. You have the fifteen-out combo draw.

Facing the shove with a 15-out draw, best?

WhyCall. Against a single pair your fifteen-out draw is about 54% - you are the favorite, getting a fair price to put the money in. This is the spot where 'just a draw' is mathematically better than his made hand.
What happensYou call; your draw gets there.  You win the pot as the favorite.
A flush draw plus a straight draw is fifteen outs - a favorite over one pair - so you raised and called off as the statistically better hand. Big draws are not underdogs; play them like the favorites they are.

A combo draw of ~13-15 outs is roughly a coin-flip-to-favorite by the river - get the money in, don't just call.
