Poker cribbage. Not the most accurate way to describe Voleur, but you are forgiven for thinking it looks like it. It's mechanistically a last-trick-only piquet but with scoring based on poker-like hands.
Two players are dealt six cards and discards two each. Then a card is placed face-up for trump. Eldest hand leads and players must follow suit, if they can't they must trump otherwise may play any card, highest trump card or card of suit led wins the trick. Tricks aren't collected and are placed before the players.
The winner of the last trick wins the value of his hand. You only score for one combination of cards but you can replace a card with the trump indicator to make a better combination. A basic combination scores while a special combination steals the points from your opponent (scores can't go lower than zero). First to 40 points wins. Unusually the deal continues with the remainder of the deck until it runs out, only then is the whole deck reshuffled.
Cribbage comparisons are thin, but strategy in discarding (albeit less consequential) and skillful card play remain. Should you discard for a high-scoring hand or a likely winner? After all, a high-value hand is nothing if it can't win even a trick.
Playing to win the last trick requires an approach different from simply winning a majority of them. Most last-trick games are luck-heavy and this is no different, the four tricks offset by only having two players.
A fine mix of games resulting in its own thing, though it does need to raise its stakes some more.
