Well I watched the replay. Im no expert but I think the thing he did wrong were:
-Bad MG placement in the building. He had 3-4 MGs and he placed them in strange, unusual spots. What was even worse was that their LOS was blocked but he didn't do anything
. Sure he got a lucky shot at 2 Strelky squads but still, they could have been used better.
-I dont think he was paying attention too much. He had 2 Volks squads in the same spot of cover and when the smoke dropped, he did nothing. Also early on he should have had his volks fallback to where his MG was. In addition his pios were just standing around at times. And they tried to take on a conscript squad (which ended badly for him)
-No mines. You had no sturmitove and he had a good amount of muni but I saw no mines at all.
-When he saw that you were heavily entrenched and camping he should have bought a mortar. And maybe a sniper to countersnipe.
BTW neos whats you fascination with this map?
. You always seem to do 1 vs 1 games on Prague
. I personally find this map to be very big
