why 5.5
NCP - Laboratory of Knight-Sergeants
why 5.5
it's literally 6
5
if you get checked 5 times, it's 0.5, and since it's not 0, you don't lose
so, technically it's 6 since you must check someone 6 complete checks to get their checks under or equal to 0
Look at the games. If you have 1.5 check and somebody checks you, you are checkmated.

Keep up the good work, we are looking forward to see your new creations!
