Simplified shuffle extension version (#2121) only the extension part of the shuffle patch is sufficient to pass [0,3.5] bounds at VLTC as shown by two more tests. http://tests.stockfishchess.org/tests/view/5cc168bc0ebc5925cf02bda8 LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 120684 W: 17875 L: 17400 D: 85409 http://tests.stockfishchess.org/tests/view/5cc14d510ebc5925cf02bcb5 LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 68415 W: 10250 L: 9905 D: 48260 this patch proposes to simplify back to this basic and easier to understand version. In case there is a need to run a [-3, 1] VLTC on this one, it can be done, but it is resource intensive, and not needed IMO. Bench: 3388643
