Everyone is very deep - 200 big blinds. A player opens to 700 from middle position and it folds to you on the button with Q♦J♦.
200 BB deep, an opener makes it 700 (3.5 BB); you hold Q♦J♦ on the button. Best?
WhyTwo hundred blinds deep is precisely when suited broadways earn their keep - the rare times you flop a monster or a big draw, you can win a whole stack rather than just a pot. A three-bet bloats the pot and forfeits that leverage, so flatting in position is the higher-EV line.
What happensYou call and the blinds fold, leaving you heads-up and 200 BB deep - all the depth still in play behind. Pot: 1,600 (8 BB).
Flop
Flop: A♦ 7♦ 3♣ - you flop a flush draw, nine outs. He bets 1,200, so you'd call 1,200 to win 2,800 (~2.3-to-1). With one card to come you're only ~19%.
By direct odds (~19% next card vs a price needing ~30%), this looks short. Best?
WhyOn the raw price this is a losing call - about 19% to hit on the next card against a spot needing roughly 30%. What rescues it is everything behind: 200 BB deep, a well-hidden flush stacks him often enough that the future chips more than cover the small gap now. That is implied odds turning a direct-odds fold into a call.
What happensYou call on the strength of the stacks behind you, not the price in front of you. Pot: 4,000 (20 BB).
Turn
Turn: 5♦ - you make the flush. He bets 3,000 - and the deep stacks are still behind.
Your flush is in and he keeps betting. Best?
WhyThis is the moment those implied odds get collected: the flush is in, and with 200 BB behind you want chips in against the set or two pair he's likely barreling. Just calling leaves money on the table - winning big now was the entire reason to peel the flop.
What happensYou raise; he commits with a set, and your flush holds. That 200 BB pot is precisely what made the thin flop call correct.
Direct odds said fold on the flop, but with 200 BB behind, the chips waiting when the flush landed made the call profitable before the card ever came. Deep stacks are exactly when implied odds do the heavy lifting.
Implied odds count the chips you expect to win on later streets when you hit; the deeper the stacks, the more a draw that direct pot odds reject becomes a profitable call.
