bank roll=$1 (more accurately: $1<=br<$3)
If you lose (1/2 probability), game over (no money to continue). -$1
If you win (1/2), game over. +$1
EV=-1/2+1/2=0
当然如果你赢了,你可以从头玩。 但EV还是“0”。
bank roll=$3
You lose 2 hands (1/4), game over. -$3
You win the first hand or lose the first and win the second (3/4), game over: +$1
EV=-3*1/4+3/4=0
