A4s pairs at least one of its cards on the flop 32.4% of the time and makes two pair or better 6.9% of the time.

Because both cards share a suit, it flops a flush or a four-card flush draw 11.8% of the time. Compare A4o at 56.8% heads-up.

When you pair your Ace, a weak kicker is the danger: an opponent with a better Ace will often win the big pots.
