Why don't chess engines take into account the time left by each player? As the current into Q1 base increases, the transistor's dissipation will increase until it equals the power dissipated by R1, after which it [the power being dissipated by Q1] will decrease; a beautiful example of maximum power being dissipated by a load (Q1) when its impedance matches the source impedance. The problem is that he does not want to use the schematic capture option, but run it from a manually crafted netlist.
