I was reading a comic and came across the following usage of 勝 which confused me.
I know what it means (Help me beat Mihashi in this game), but I'm not sure about how to parse "勝たしてくれ". "くれ" looks like it comes from "くれる", and I want to say that "して" is the connective form of "する", yet I've been completely unable to find a noun or suru-verb "勝た" in any of my dictionaries. The other possibility I considered was "勝たして" came from a verb "勝たす", but once again I couldn't find any such verb. What's going on here?
