The way I see it, if I'm in early position and I plan on calling a bet (say with middle or sometimes bottom pair), I might as well lead out myself if I'm in early position. I would only check/call in early position on certain draws.

If for example I'm heads-up in late position, calling the flop generally results in being bet into on the turn and river, costing 2.5B for a showdown. If I raise the flop with top/mid pair or a draw, I can take the lead 90% of the time on the turn and bet, or check to continue drawing for cheap. To raise flop / check turn with a draw, I see the river card for 1 bet plus I get fold equity on the flop. Being raised on the flop, my opponent might not even bet the river, giving me a showdown for 1 bet! To call/call/call, it costs me 2.5 Bets for a showdown and there is no chance my opponent will fold.

What situations exactly should I be calling in ?
