E38 Nimzo-Indian: Classical, 4...c5 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5 5.e3 O-O)

E38 Nimzo-Indian: Classical, 4...c5 (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 c5 5.e3 O-O)

The score in the blitz match I played in 2016 after this 36th game was 24.5 - 11.5 in my favor. According to the result percentages, the game went on in slight favor of White up to the move 4...c5 and starting from 5.e3, the percentages are in favor of Black. When I look at the result statistics for the more often played moves, 5.dxc5 is the only move that has a positive result for White, which LiveBook states to be 55% in 4122 games.
