could somebody recommend some techniques, how to test small improvements of your chess engine? the only way i know to test whether a certain change is an improvement or not is to play hundreds of games vs other engines and then compare your new version score to the old one. this consumes so much time and anyway its good for major improvements, but small ones usually aren't visible. are there better ways to do this? meybe playing a series of fixed opening lines (2 games for each opening) could allow me to reduce the ammount of games needed to get a reliable result. another question would be regarding time controls of these tests. if i'm playing for example 2+2 games, is the result as reliable as the one i get playing 20+0 (same ammount of games). the changes im speaking about are for example added extensions/reductions, or added eval knowledge, not the speed improvement with the result of same nodes.
