Question on raising/"one chip rule"

[bav]

I vote for "call". The intent is ambiguous. A single $5 isn't enough to call so the player had to put out more than one to do the call. Since he said nothing, you go with the least aggressive choice. If he put out 3 $5's, it's a raise. Two $25's is a raise. Ten $1's is a raise. A $25 and a $5 is a raise. But two $5's is a call.
