Revert "Halve king eval margin" This reverts commit 4b3a0fdab03a7529ede42891963d3036712a0bd5. As Gary says: " It failed when I tried it at long TC previously, and only barely passed this time. Some anecdotal evidence is that it hurts vs other engines as well (the Lightspeed rating list showed a 16 elo drop from previous best version - still +- 5 error bars on both, but that's still significant)" I also agree that if we have some doubts (like in this case) it is better to be safe than sorry. bench: 4615572
