Hy Cobra!

At first I have to say - thanks for all of your threads! I´m sure you´ve done them for not for me^^ but I´ve lerned a lot out of them.
So my two cents to your hand...

I think your equity in general is good, but I don´t like the huge raise. You said in general he plays draws passivly so I would give him just a few for his range.
Here is what I would stove (ca).:

So, I would shove it but don´t like it too much. (maybe that´s just because of my last experiences against fish...)
