I have a problem with my odds
This is the problem: I flop a hand that is probably dominated but has some potential (like second pair with ace kicker). Someone bets pretty weakly, like half pot size or less. I very much consider folding, but then decide to call and hope for twopair or trips. The odds are not so incorrect.
Turn comes, no trips or two pair and the bettor puts out another weak bet, the same amount as last time. As the pot is now almost twice as big, I call again. River comes and all I have is second pair with Ace high, bettor throws out ANOTHER weak bet of the same amount. By now, the pot has grown so much that his bet is just 1/10 of the pot, and I think "well, there must be one chance in ten that I win this hand". Bettor has TPGK and wins the pot.
Now, is this kind of chasing somewhat correct? When someone with top pair bets weakly, he´s giving me free cards, right? The problem is, that in the first place (at the flop) I think that I will fold if I don´t hit but then I don´t, because I look at the pot and count and if I could call at the flop, the odds are about the same to call on the turn.
What do you think? When is the right time to get out of the hand?
