Did i play this too weak or saved myself money?

[Black winter day]

All players are TAGs and i wanted to leave the table when i got dealt AK.I wanted to check the flop, but i was thinking, that i give them free shot if they have hit only piece of the flop.And betting into 3 other player announces i have a strong hand, so if i get called, i was gonna give up.
