I've been card dead for 30 to 40 hands and also haven't found many situational spots to take advantage of. I've been at this table for about 25 hands and played 2 of them, in both cases open pushing from LP to take the blinds.

The CO has been tight, and this is the first time he's gone after my blinds. My first instinct was to push, but CO would be getting close to correct odds to call with any two and might well have a better hand anyway.

Folding seems way too weak considering my chip position, so I dismissed that option fairly quickly.

Is this a good spot for the stop n' go, or is my hand strong enough that I should just push?
