Troika! How to check for normal skill or action?

For example a player wants to kick a door open or transport glasses over a slippery wet floor. The player has no fitting advanced skill for those.

The base SKILL is 1d3+3 which can be very low. Rolling that under 2d6 is very hard. Everyday tasks become impossible. I could let them spend extra LUCK to boost their roll but that feels unnatural. Players tend to save their LUCK when they need it.

Alternatively I could let them roll 2d6 + SKILL versus or under a given difficulty but the Troika! does not have any rulings for this.
