Re: Arasan test, the aftermath, record 4.86

Post by jdart »

So, if I can summarize:
4.86 - looks like two moves are similar in score; neither is really winning. Probably should remove this one.

4.50 Rxf6 is better but h4 is similar - should possibly be alternate solutions (or this test should be removed)

4.92 I already put Nd2 and Bh3 as alternative solutions in the latest test version - these are both winning & better than other alternatives I believe.

6.16 Rxd5 & Nxf7 are similar in score - should possibly be alternate solutions (or this test should be removed)

I removed the others you mention from arasan8.epd already.
