On my Board 3 of the Summer 2020 NABC Robot Individual Day 2 of 3 I got a cold top on a hand I had estimated to be an average. When I analyzed what brilliant play I must have made unconsciously, I discovered that I played the Q-S as declarer on Trick 2 with KQx opposite Jxx and West won with the Ace. At this point every card played is compelled after the opening lead which was the same at every table, except declarer has a choice of which spade to play. 5 tables played the S-Q like me and dozens of other 1NT by S tables played a different spade. In every case, declarers who played the S-Q get a club returned by Robot West, every declarer who played the S-K or S-x got a spade back. Robot West's decision is not based on simulation analysis, it is purely deterministic. How is it that playing S-Q specifically is so intimidating that Robot West abandons the attack on spades, and instead gave me a chance to play the hand for an extra overtrick. The programming favors declarers who played S-Q, it should be neutral and give everyone the same return at Trick 3, like everyone got the same opening lead. Robot West obviously did not use simulations to decide what to do on Trick 3 or it would have consistently returned a spade or consistently returned a club since playing S-Q vs S-K at Trick 2 stands up equally to all simulations. But the programming overall is excellent, except I dont like the interruption "Are you there?"that comes up way too often when I haven't been idle. Jeff Rhodes
