Re: Warm your engines

[d] 2rr1k2/5Ppp/1p6/p2B4/n7/4P3/5PPP/R4RK1 w - - 1 24 Here Minic played Bb3, that was probably a bad decision ... Reanalyzing this position at home with more time, Minic goes for Bb7 but never stick to Be6 that is SF suggestion here to old the position... 24.Be6, Rxa4 and Bb7 seem to be playable. M...

Leela's main line! About the thread's questions, yes, ...Bg4 has the edge (over the not much worse ...Bb6!? and the also not much worse ...Rcg8!? e.g.) and yes, "my" engine SF finds/agrees, but no, it doesn't "struggle" and it doesn*t need Backward to "find" 1...Bg4.
