I’d say he had a read on you. He reps the flush but you don’t fold. He fires again on the river…only way he can do that is if he believes there is a good chance you will still fold. Great read by him. He reads you as weak or holding nothing. He shows so that means he reads you as weak.

You might try calling down the next 5 flushes that show (that are fairly cheap like this one). You will find people have them much less often than you think.
