I've built a good stack (top 15% - 20%), cruising and this happens against only player at table who covers. We are in the money but field is massive with about 1600 left. $18K up top. I have no reads on oppo as i was moved to table 20 hands prior. I have been opening at least twice a round though so he may feel i am active and can be 3-bet light. I basically jam to fold out Ax diamond draws and think i am gonna be called with worse (10-10, J-J and QQ).
thoughts? is it a spew? can i play this better? 50p? trivial?
