I do not believe it and you probably have a bug in your new qsearch.

I use no hash in the qsearch but first check in the qsearch was a clear
advantage for me in the qsearch was an advantage for me.

I can add that I get 282/300 in less than one second on WAC with P1000.
I used wacnew and I wonder if you used a different test.

For example I wonder if you have bm Qxa8 d6 dxe6 g3 for position 31


Here are results of movei in the first positions(number of nodes to solve the
position because time is not interesting:
position 1  2106 nodes
position 2  not solved
position 3  1215 nodes
position 4  105 nodes
position 5  47 nodes
position 6  105 nodes
position 7  175 nodes
position 8  335 nodes
position 9  86 nodes
position 10 89 nodes
position 11 191 nodes
position 12 65 nodes
position 13 117 nodes
position 14 142 nodes
position 15 74 nodes
position 16 393 nodes
position 17 387 nodes
position 18 2548 nodes
position 19 449 nodes
position 20 113 nodes
position 21 11308 nodes
position 22 426 nodes
position 23 15377 nodes
position 24 264 nodes
position 25 112 nodes
position 26 341 nodes
position 27 212 nodes
position 28 131 nodes
position 29 7506 nodes
position 30 21064 nodes
position 31 59 nodes
