The level to get to the 3th division is clearly better than tscp. The level of tscp is not enough even to promote to the 4th division. You may ask Leo to use the last Celes but I doubt if it is going to be strong enough to promote. For the low divisions the level that is needed to promote is higher than the level of the higher division. It is not going to be the case in the high division and part of the programs that pronmoted to the first division went back to the second division. Abrok,Biglion,Knightdreamer,List,Rdchess,Tao and maybe gnuchess(if Leo finds it stable) may fight for promotion. It seems that Celes needs to be better than one of them in order to promote. 7th place may be also enough for pronmotion if Celes can beat Soldat.

If you play more than 40 games then I agree but if you play 40 games you get no repetition when you always change the first move(the only way to get repetition is changing the order of moves but it does not happen often when the first move is 1.a4 or 1.f3(it can happen in 1.e4 e6 2.d4 to 1.d4 e6 2.e4 but I do not see logical change from 1.a3 e5 2.e4 to 1.e4 e5 2.a3 Uri
