You can specify a player's range of hands in any of the following ways:

• enter the word random to include any hand, omitting those using board cards or other players' cards
• enter two specific cards, separated by a space: Kh Qh
• two ranks: for example, AK, or TT
• two ranks, followed by an "s" for suited hands only: AKs
• two ranks, followed by an "o" for unsuited hands only: AKo
• an open range. TT+ means all pocket pairs with tens or higher. A7+ means "AK,AQ,AJ,AT,A9,A8,A7"
• a closed range. 77-KK means "KK,QQ,JJ,TT,99,88,77"
• multiple ranges separated by commas: AA,AQs,77
