Acutally, having an Ace is not that underrated esp with newbs. A lot of them, will see an Ace with any card and go for it.
But we should know that A and any low card is worse than say K Q.
The fact is, the Ace can beat ur cards, when there's no pairs or hit the Ace. But then, it evens out that either of ur cards when paired can beat his low card pair. Plus of course, you have a chance of getting the straight.
And I say KQs is pretty good, just go by the hand strength table. It's more like a win alot of or lose a lot type of hand. Same with any other strength by suited hands. Cuz chance of getting flush is not that high, but ppl who get high pairs get lured in and bet a lot.
