一个玩家有两种可能获胜的方式，要么他在摊牌时有最好的牌，要么他在下注轮迫使其他的玩家弃牌。随着对手弃牌的可能性增加，他获胜的机会也提高。<\/p>

\n根据牌力大小属于一个玩家的底池份额被称为底池赢率（pot equity）,根据他的对手的弃牌可能性被称为弃牌率（fold equity）。\n<\/p>

\n当计算期望收益时，一个玩家会计算收益x获此收益的可能性，比如10%。<\/p>

例子:
\n<\/b>\n<\/p>

\n两个玩家在摊牌前的最后下注轮。玩家A有20%的机会赢得摊牌。玩家B在玩家A下注时将在10%的情况下弃牌，在其它情况下，他将跟注。底池有$4，下注的大小是$1。\n<\/p>

\n期望收益(下注<\/a>) = 20% * 收益(B跟注且A赢得摊牌) + 10%
\n* 收益(B弃牌)+ 70% *收益(B跟注且A摊牌)<\/i><\/p>

期望收益(下注<\/a>) = 20% * 5$ + 10% * 4$ + 70% * (-1$)<\/p>

期望收益(下注<\/a>)= 0.7$
\n\n<\/p>

\n因此，这个玩家在20%的情况下赢得$5，在70%的情况下损失$1。总的来说，他下注$1将赢得$0.7。<\/p>

\n
\n把这个结果与B既不下注也不加注和A只是观让的情况比较:<\/p>

期望收益(观让) = 20% * 4$ + 80% * 0$<\/i><\/p>

期望收益(观让) = 0.8$<\/p>

期望收益(观让) > 期望收益(下注<\/a>)
\n\n<\/p>

\n因此，在这个例子中，玩家A只是观让较好。<\/p>
