Congrats...
I like weak leads when I'm pretty sure I can get a raise. How to play it from there is a tough one sometimes. Some opponents especially when they check raise my weak lead when I have position, it looks like a position bet on a straight draw or A9 or some small pair that might be good now. It maybe best to just let them hammer again at the turn before raising, and others to even wait for the river because the value bet is their stack. It is tough to say the best course of action, but on a 9 high board a ton of scare cards can come off for JJ, so maybe all in now is the king.
Others stacking them now is the only option. If you call here it will give them time to think they are beat, instead of being in the heat of the moment, or scare cards can come off that kill the action. The intimidating board can work to your advantage as you may be pushing with a draw, which if you have been doing against shorter stacks looks reasonable to a bigger stack player now. It is my one real argument for taking a bunch of higher variance situations for 10-20% of my stack. Gamble it up with short stacks, hammer the bigger money.
So maybe it is partly board and position dependant as to your move... out of position two suited all in now, rainbow all in at the turn? in position against an aggressive check raiser, all in at the turn on a rainbow flop?
