3 of a kind.

Tony picked up his cards, & looked at:

Ace of clubs

Queen of clubs

3 of clubs

3 of diamonds

3 of spades

It was a no-brainer. Tony keep the 3s, & drew:

Jack of Diamonds

10 of Hearts

Well, a set of 3s might not be the winning hand, but it was sure to prevent Tony from having the losing hand.
