So, this opponent has taken about a dozen small pots by over shoving. I figure he is doing these shoves with all sorts of hands, ranging from middle pair, top pair, and heavy draws. I am sure he is thinking that I am missing a whole bunch and I think he thinks I am dumping all of my draws. I also feel that he is shoving on cold bluffs, not that I was able to call yet.

With the blinds getting so high, is he getting desperate yet?
