That's Poker

Double aces, let's go all in
Rivers three kings, well I can't win
A pair of kings, again all in
A straight, I take it on the chin

I flop two pair, but he flops trips
And so he takes a pile of chips
A straight, I quickly bite my lips
With quads the win from me he rips

Just when I think I'm all done in
A pair of twos gives me the win
That's poker with its ups and downs
It's not as simple as it sounds
