I am a weak player that can be pushed off decent hands. One thing I have started doing is using pot odds to help me call in these situations. Eg. Pot is $1.87 and the river bet is $.50. Do I call? The bet is only 21% of the pot so if I think my hand will beat his more than 21% of the time then I call it. It’s a judgment call but it has helped me call big bets and win when I otherwise would have folded. I think my logic is sound. If it is not, someone please tell me. Hehe.
