it could be stopped for making that forced move for you

like in anti chess i often hover my mouse over all my pieces to see which pieces i have-to move .. so that i can concentrate on the possibilities which i have .. that way i will less easily overlook something

if the forced moves wouldnt show up ... i would have to think about all pieces .. and likely miss some moves which might be better

so it can make it a lot easier for newbies like me when forced moves are shown .. but i think its less nice for better players who wont need it and might consider it artifial help :)
