Number of cashes
Before it gets to you there is already 3k in the pot which is 20% of your stack, stop being greedy and shoove!!! Why raise to 6k putting 40% of your stack at risk to try and stack him? Use your FE and pick up that 3k and go on to the next hand. If you had QQ+ then raise but anything lower is too difficult to play post flop. Shove pre if he calls with K10 high five the monitor and pray for no K!!!
