For what its worth, i agree with ogba here just because conventional wisdom tells you to shove with pretty much any two way before this in most cases that can be a disasterous move. Ive seen pro players get to nine BBs and shove with 7 2 off obviously, they bust out. Not sure about the K 6 but deffinitely my ITM rate went up when i learned to wait for a better spot. Any suited ace or two big picture cards shoved with 6 bbs is way more likely to hold up versus two random cards with 10 BBs. Sure some times you steal the blinds but generally theres an uber aggressive German or just a donk who will call with anything higher than a nine, at the end of the day if i want to stay in the game then i like to have outs or at least the highest card. I can remember so many times when i was at deaths door and came back to win just cos i was patient.

Quick edit: It also helps to know that your opponents are capable of calling with anything higher than a nine, also why just give up after sitting there for an hour then throw away your time and money?
