Deep Stack
A deep stack is a chip stack that is large relative to the blinds, often 150 big blinds or more, allowing more postflop play and bigger implied odds.
A deep stack is a chip stack that is large compared with the blinds. A standard cash-game buy-in is often around 100 big blinds, so players usually call a stack "deep" when it is noticeably more, for example 150 or 200 big blinds or above. A "deep stack tournament" is one that gives players many chips relative to the starting blinds, so there is more play before the pressure of rising blinds sets in.
What really matters is the effective stack: the smaller of the two stacks in a hand. If you have 300 big blinds but your opponent has only 40, you are effectively playing a 40 big blind hand.
How deep stacks change strategy
- Bigger implied odds. Small pairs and suited connectors become more valuable, because when they hit a set, straight or flush there is a lot left to win.
- One pair loses value. With many chips behind, a big pot usually means someone has more than one pair.
- Position matters more. There are more streets of real betting, and acting last helps on every one of them.
- More room to bluff. Bets on the turn and river can be large without committing your whole stack.
Worked example
Blinds are 1/2 and both players have 400 chips, which is 200 big blinds. A player in the cutoff raises to 6, you call on the button with 6♠ 5♠, and both blinds fold. The pot is 6 + 6 + 1 + 2 = 15. Each of you has 394 behind, a stack-to-pot ratio of more than 26.
The flop comes 7♥ 4♠ K♣, giving you an open-ended straight draw. The turn is the 3♦ and you make a straight. If your opponent holds a strong hand like K♦ K♥ or A♣ K♠, they may be willing to put a large part of their 394 into the pot. That large potential payoff is why calling with speculative hands works better deep than short. With only 30 big blinds, the same call would risk a bigger share of your stack for a much smaller reward.
Common mistakes when playing deep
- Overvaluing top pair. Getting all 200 big blinds in with A♠ Q♦ on a Q♣ 8♥ 3♦ board is often a mistake against a cautious opponent who suddenly raises.
- Playing too many weak offsuit hands. Implied odds help hands that make strong, well-hidden hands, not hands that make weak top pairs.
- Ignoring the effective stack. Your deep stack only matters if your opponent is also deep.
The opposite of a deep stack is a short stack, where most decisions happen before or just after the flop.
