I thought about checking intending to call all in, but a) was scared of Ax [img]/images/graemlins/club.gif[/img] and b) didn't want to give free card to draw

although his most likely holding is c) PP &lt; QQ I think, so maybe if this read is right, I should let him try to bluff me off of KK/QQ?

Not sure what I should do here
