I have pushed 2 of the last 3 hands. The last time he min raised (the first of those last 3) he folded. This causes concern that he actually might have a good hand. He has played the bubble in a manner 2p2 would approve of. I think it's a push, but I want to see what you guys have to say.

Thanks in advance,

dirty
