What is the Rule of 2 and 4?

A quick mental math shortcut: multiply your outs by 2 to estimate the percentage chance of hitting on the next card, or by 4 when two cards are still to come (flop to river). It gives a rough approximation: 9 outs on the flop = ~36% to hit by river.

What is +EV in poker?

Expected Value (EV) measures the average profit or loss of a decision over many repetitions. A +EV call means you expect to gain chips in the long run. If pot odds exceed your hand equity, calling is +EV.
