Here is a diagram for the relevant position that happened in a game
(Gambit-Nimzo)

I gave Gambit to forget about everything after playing the moves bxc6 Rc7 by
downloading tiger13 and downloading gambit again because I did not want gambit

do not do it)

[D]1k1r4/p2r4/1pn5/1P2p1q1/P3Qp1p/5P1P/2R3P1/6BK w - - 0 1
