In August 1919, White Russian forces under the command of General Malentov captured the city of Tabov during the Advance on Moscow. They nearly captured Trotsky himself.
What if they had captured Trotsky and executed him?
It isn't enough to bring about a White victory on its own, but maybe with the right PoD beforehand it could be part of a snowball effect that does win the Whites the war. Postwar if the Communists did win anyways, this either makes things harder for Stalin due to a more likable and charismatic figure taking Trotsky's place in the Left of the CPSU or makes things easier because it means there is one less opponent to eliminate.
