The bid tokens need to be taken out of the cardboard holder VERY carefully. If any part of the token back is even the slightest bit torn in the removal, players will learn what that bid is and will go for it or avoid it. Rio Grande would do well to print more of these and offer them for people who have mishaps when punching these out.
The game was mountains of tactical options within each hand and nothing is ever left completely to chance except for the one odd combination mentioned above. This is a very good, light card game that is bound to provide a great deal of enjoyment for all fans of trick-taking games.
