on the first one, i think you've got enough time to make a more +EV move than trying to steal with Q9s... it's not a terrible spot, but there's no urgency yet.

second, i lay it down. i know you're under 10BB but against any two randomly, this hand isn't going to hold up well and the two stacks left to act are the two biggest stacks at the table.

third, push. you've got decent FE and AJs is a good-looking hand here.
