playing with one queen less, the only question is how to translate it in concrete advantage? 28.e5

29.Be3
Be3 is supposed to be the bad bishop behing his own pawn of the same color, meanwhile the Bg7 is supposed to be the good bishop, it is just not the case here, just comparing their mobility and the number of squares they can control

Poor Knight, I asked pupils of 2 years old training and they see that the Knight can be capture thanks to the control of a file! Number of potential attackers of the Knight is greater than the number of potential defencer. Poor Black queen... 36...Kf7
