I've found the answer (or one of... but honestly I think it's the only one 😄) and, again, thanks for your time!

Here is the code:

policy_rule = <<RULE
{
 "if": {
  "allOf": [
  {
    "value": "[contains(string(field('tags')),parameters('tagName'))]",
    "notMatch": "True"
  },
  {
    "field": "type",
    "equals": "Microsoft.Compute/virtualMachines"
  }
  ]
},
  "then": {
    "effect": "[parameters('effect')]"
  }
}
RULE

Then, if you `tagName` is **RigorousMakesMeHappy** and whatever the tagValue is you will be compliant or not with:

```
RigorousMakesMeHappy: ✅ (compliant)
```

rigorousMakesMeHappy: ❌ (not compliant)

```
RigorousMakesMeHapPY: ❌
```
```
qsdfqsdfqsfd: ❌
```
```
yougettheidea: ❌
```

policy_rule = <<RULE { "if": { "allOf": [ { "value": "[contains(string(field('tags')),parameters('tagName'))]", "notMatch": "True" }, { "field": "type", "equals": "Microsoft.Compute/virtualMachines" } ] }, "then": { "effect": "[parameters('effect')]" } } RULE
