In a match this weekend, not once, but three times my wrestlers opponent used one or two fingers while working for an escape/reversal. I asked the ref why she didn't stop the match and award my wrestler a point and she said the bottom wrestler didn't apply pressure. I asked her how the bottom wrestler was able to move the top wrestlers hand away from his waist without applying some sort of pressure to which I was told they didn't see that. What's the rule on hand control using fingers?
