GLOSSARY
The words used on this site
16 entries — hand notation, equity, outs, coinflips, domination and pot odds. Only the words you need in order to read an equity table.
- s (suited)
- A trailing s, as in AKs, means both cards share a suit. The same two ranks suited are worth roughly two points more equity than offsuit. Four combinations exist.
- o (offsuit)
- A trailing o, as in AKo, means the two cards are different suits. Twelve combinations exist, so you are dealt an offsuit holding three times as often as its suited twin.
- Pair notation
- A hand written without a suit letter, such as 77, is a pocket pair — six combinations. The 169 total is 13 pairs plus 78 suited plus 78 offsuit.
- Equity
- The share of the pot a hand wins on average if the hand is played to showdown, counting a chop as half to each side. Every percentage on this site is equity in that sense.
- Outs
- The number of unseen cards that would give you the winning hand — nine for a flush draw on the flop, for example. Preflop equity here is computed by dealing every board rather than counting outs.
- Coinflip
- A matchup close to 50/50, classically a pocket pair against two overcards such as 88 vs AKo, where the pair is a fraction ahead.
- Domination
- Two hands share one rank and the kicker decides the pot — AK against AQ, for instance, where the favourite runs around 70%.
- Pot odds
- The ratio between what a call costs and what the pot pays. The equity you need is the call divided by the pot after the call; if your equity clears that, the call is profitable.
- Heads-up
- A pot with exactly one opponent. That is the number you get by selecting one opponent on the front page.
- Multiway
- Three or more players contesting the pot. Every extra player lowers each individual equity and raises the relative value of suited and connected hands.
- Combos
- The number of concrete card pairs a notation covers: six for a pair, four suited, twelve offsuit. In total 6×13 + 4×78 + 12×78 = 1,326 possible two-card hands.
- Chen formula
- Bill Chen's scoring system for starting hands, adding and subtracting for high card value, suitedness, gap and straight potential. Every hand page on this site lists its score.
- Suited connector
- Adjacent ranks in the same suit, such as 76s. They can make both straights and flushes, which is why they gain value in multiway pots.
- Broadway
- Two cards of ten or higher — AK, KQ, JT and so on. Strong hands, but also the ones most exposed to domination.
- Set
- A pocket pair that hits a third card of its rank on the flop. Every pocket pair does this about 11.8% of the time.
- Kicker
- The side card that decides a pot when both players make the same pair. It is what separates AK from AQ when an ace flops.
