Poker Equity & OddsSuited vs offsuit: how much does suited add?
Short answer
Being suited is worth about 2 points (1.7 to 2.0) of equity for big cards against a random hand: AK suited has 67.0%, AK offsuit 65.3%, because two suited cards make a flush by the river only 6.4% of the time. Small connectors gain more, because a flush is one of their few ways to win a big pot: 76 suited has 22.5% against aces, 76 offsuit 18.7%.

Big cards gain about two points
Suited. That's a flush draw before the flop.
| Hand | Suited | Offsuit | Suited adds |
|---|---|---|---|
| AK | 67.0% | 65.3% | +1.7 |
| AQ | 66.2% | 64.4% | +1.8 |
| AJ | 65.4% | 63.6% | +1.8 |
| AT | 64.6% | 62.7% | +1.9 |
| KQ | 63.4% | 61.5% | +1.9 |
| KJ | 62.6% | 60.6% | +2.0 |
| A9 | 62.8% | 60.8% | +2.0 |
The gain sits between 1.7 and 2.0 points for every big-card hand here. Two suited cards make a flush by the river only 6.4% of the time, and some of those flushes win pots the hand was winning anyway, so the gain stays small.
It depends who you are up against
| Matchup | Suited | Offsuit | Suited adds |
|---|---|---|---|
| AK vs QQ | 46.0% | 43.2% | +2.8 |
| AK vs 22 | 49.9% | 47.4% | +2.5 |
| AK vs AQ offsuit | 75.4% | 74.4% | +1.0 |
| AK vs 72 offsuit | 69.1% | 67.6% | +1.5 |
| 76 vs AA | 22.5% | 18.7% | +3.8 |
| 76 vs KQ offsuit | 40.8% | 37.2% | +3.6 |
| 76 vs 22 | 53.3% | 51.1% | +2.2 |
| T9 vs AK offsuit | 40.5% | 36.9% | +3.6 |
Suited helps most when the hand can only win by making something big. AK against AQ already wins most boards with its king kicker, so the flush adds 1.0 points. 76 against aces almost never wins with one pair, so it needs two pair or better, and the flush is worth 3.8 points. T9 against AK also has to beat a pair of aces or kings, and gains 3.6 points.
