Wow. I don't know how many times I've almost posted hands here. It's obvious I should raise. I induced that bet from an ace by checking the turn and now I should follow up... I guess I was scared of a higher flush but they donkbet 80% of the time on this river, hoping you have the ace.

Who else does this? Converts hands, looks them through and never posts them because you find the answer to your question yourself?
