3 hands at 5/10 today

there wasn't really any hard and true reasoning to capping hand 1, but in my experience, if the person that "didn't" cap it preflop bets the flop, he has a very premium hand.
as for hand 2, i should have folded the turn, but folded the river after the straight draw was completed.
and hand 3, i checked the turn cuz i liked it, if i was ahead, i still was, if not, i wasn't, and i felt that i was. so i donked the river because it seemed pretty obvious i had an ace and didn't want a lower pair checking thru.
