We compare a pocket pair with a suited hand. The non-pair hand shares a rank with the pair, so two of its outs for pairing are blocked by the pair itself.

The lead is steady rather than large, and the flop still has plenty of say in who wins. Of every 100 boards, about 4.92 are split pots, and the equity figures already include them.

By strength against a random hand, 33 holds place 66 of 169 and 43s holds place 150.
