Looks like a blocking bet to me. I'm jamming.

seems very standard all streets I'd call riv without dynamic.

I'd prefer at least a slightly larger raise preflop. River I'm jamming. Even given stats alone, I don't see villain folding 9x very often and might very occasionally call with some strongish (i.e. weak) 2p hands.

Meh I nitfold this pre because I fucking hate the sopts I find myself in with ace rag, but if you're confident post flop with this then fine.

Post flop I take this line, probably just call river because I can't see him calling off much worse. This can easily be a boat.

raise more pre, raise fold the flop, raise the river
