Playing the English has received great reviews, but readers also pointed out some lines that should have been included in the book. So we asked author Nikos Ntirlis to produce an update and he delivered more excellent material. You can read the APPENDIX PDF at that link. The same material is also linked at the book’s webpages, so it should be easy to find for all readers. Hope you enjoy the update and that it helps 1.c4 players to even better results.
