In [[contract bridge]], a '''two suiter''' is a hand containing cards mostly from two of the four [[suit (cards)|suits]]. Traditionally a hand is considered a two suiter if it contains at least ten cards in two suits, with the two suits not differing in length by more than one card. Depending on suit quality and partnership agreement different classification schemes are viable. The more modern trend is to lower the threshold of ten cards to nine cards and consider 5-4 distributions also two suiters.

The six possible combinations are given the names "[[major suit]]s" (spades and hearts), "[[minor suit]]s" (diamonds and clubs), "[[black suit]]s" (spades and clubs), "[[red suit]]s" (hearts and diamonds), "[[pointed suit]]s" (spades and diamonds), and "[[rounded suit]]s" (hearts and clubs).

When including two suited hands with 5-4 distribution, two suiters have a high [[Bridge probabilities|likelihood of occurrence]], and the modern [[preempt|preemptive]] style is to incorporate such two-suited hands in the arsenal of [[preempt|preemptive openings]]. Example of such a preemptive conventional opening is the [[Muiderberg convention]]. Some take this aggressive style even further and use [[Ekren convention|Ekren]] to preemptively open on a 4-4 in the majors. 

Conventional [[overcall]]s such as [[Michaels cuebid|Michaels]], [[Unusual notrump]], [[Ghestem]] and [[Raptor convention|Raptor]] are designed to introduce a '''two suiter''' over an opening bid of the opponents. Conventions like [[Landy convention|Landy]], [[DONT]], [[Lionel (bridge)|Lionel]] and [[Comfy Canapé|CoCa]] can be used to denote a '''two suiter''' over an opposing [[1NT]] bid.
