Profile of Lümmel

-First of all you see in the Fog of war that he built tier1, if he didn't cancel it.
That probably means M3 and/or snipers which means for you - keep your units together and don't spread them apart too much.

-Since he built t1, i wouldn't recommend building a kubel. The m3 softcounters your kubel and you have nothing to deal with the m3 in the first minutes if you don't get a Raketenwerfer.
You are doing very good in the first minutes by keeping you units together and focussing on the m3.
Also, you are keeping your kubel at max. range to prevent damage from the m3 - well done.

-You went t3 after that to get a Puma, which is an effective way to get rid of the m3s.
Personally i would have bunkered a little more and have waited for t4 to get a luchs.
Then you would have a good light tanks to hard counter the m3s and any soviet infantry.

-Your choice was the better one tho, cause he went for fast t3. Remember to keep your puma at rangr (Puma:50 range, t34:35 range), and use the reverse mode more often! There were quite a few times (i counted 5) where the Puma was facing its butt to the Soviets.

-Your choice to go for the Stuka was good, too. The 120 was hurting you baldy, and you took it out with the first shot of your stuka, good choice.
What the soviet was clearly doing wrong, he didn't try even once to flank your "blob" in the middle. 1 t34 from front and one from the side with some Flame Penals would have hurt you more.

-Loosing his first t34 was beyond stupid. He was probably going for your stuka. You chased him down well, when he was retreating.

-Your enemys commander choice wasn't the best either: t3 with t34/76 plus t34/85 call in: why?
Then he even went for t4 to ge a katyusha and su85. Again: questionable.

-What i wouldn't have done is going for the second Stuka. You know he had 2 t34, what if he called in another 2 t34/85? One precision shot of the Katyusha (he had the vet and the ammo) and your 88mm would have been taken out temporarily. Your only at would have been a Puma and 4 Volks with Shrecks.
The better choice would have been a Panther here to be safe in late game.

All in all you made the right strategic decisions to counter his (questionable) decisions.
Another thing: When you cant win a fight, don't let your squad last till it has only one man left, retreat instantly to save mp.

Good game and a polite and friendly chat, i like

Well my fault was obviously to count on snipers and build t1 right away. I lost 1 m3 early on but built 2 others, but of course they couldn't manage to get rid of the 4 kubels.
I built snipers, cause i wasn't expecting a shameless kubel abuse by a ranked 88 team.

When i played too much that day i kinda keep playing in my dreams.
Its just like as if i was sitting right in front of my computer: i'm seeing units move and i dream about how i would react to it.
It's really strange

Soviet Cheese MG Spam into t34 into ISU on Minsk. Not fun for ze Germans.
