SALC V5 openings and books launched
Posted: Sat Jan 13, 2018 7:58 am
I just released my brand new SALC V5 openings and books.
SALC means "S"hort "A"nd "L"ong "C"astling: white and black castling to opposite sides (if white played 0-0, black played 0-0-0. If white played 0-0-0, black played 0-0).
When using SALC-openings, the chance for attacks towards the opponent king is much higher than using normal opening-books. Because of this, computerchess using SALC openings, will bring more action and fun to watch (and a measureable lower number of draws), because the faster the computers get, the higher the quality of computerchess get and the higher the draw-rate in engine-engine-matches get...so the computerchess is in danger to die the "draw-death" in the near future. So, using SALC openings will give computerchess a future beyond playing only draws or using strange and incorrect gambit-openings for a lower draw-rate!
What is new in SALC V5 (compared to older SALC V1 - V3) ? SALC V5 contains half-closed SALC-positions, only. And that leads to measureable lower draw-rates, compared to older SALC-versions - take a look at the testing-results on my website. So, it is strongly recommended to use the new SALC V5 openings from now, only and not the older SALC-versions.
These are the half-closed filters:
3) On d-line or e-line at least one white and one black pawn (=one of both center-lines closed)
4) no pawn-capture on the center-squares (e4,d4,e5,d5) possible (means: not allowed: (white pawn on e4 and black pawn on d5) or (white pawn on d4 and black pawn on e5) - so, the position cannot get fully open after 1 or 2 played moves by the engines.
5) no pawn-free d-line, when both queens are on d-line. So, the queens cannot capture each other after 1 or 2 played moves by the engines.
The idea is, that in these half-closed positions, the probability of fast and many capturing-moves is much lower, so it should took more time (and moves) to reach drawish endgame-positions. So, the probability of an interesting and long midgame should get higher...
