I'm pretty unhappy at the value missed, but not too mad at my play, as in other scenario's the villain calls here. But after thinking about it, his bet looks like a blocking bet, and how much should i raise here to get paid off. Maybe he doesn't call any raise here and i didnt't miss value?
Opinions appreciated!
