Trips on Flop - Turn str8 scare card

[DonCologne]

Buzz your calculation is wrong. Hero wins only 46.95$ (Hero has only 16.95$ left and so he plays to win the 30$ in the pot and villains 16,95$) if he scoops and if he ties it is only 15$ (Hero plays only for half of the money in the pot before the turn bet).

The play is +EV, but only because hero has not much more than a half potsize bet left:

46.95$*10/42 + 15$*3/42 - 16.95$*29/42 = 11,17$ + 1,07$ - 11,7$ = 0,54$
