It was tried a couple of times by now but now it passed. Performance is not enormously good but this patch makes a lot of sence - blockers for king can't really move until king moves (in most cases) so logic behind it is the same as behind excluding king square from mobility area.

Seems like PvNode check in condition of last capture extension is not needed. Note - even if this is a simplification it actually causes this extension to be applied more often, thus strengthening effect of @MJZ1977's patch. passed STC http://tests.stockfishchess.org/tests/view/5deb9a3eb7bdefd50db28d0e LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 80244 W: 17421 L: 17414 D: 45409 Elo +0.03 passed LTC http://tests.stockfishchess.org/tests/view/5deba860b7bdefd50db28d11 LLR: 2.94 (-2.94,2.94) [-3.00,1.00] Total: 21506 W: 3565 L: 3446 D: 14495 Elo +1.92 Bench: 5097036
