The partner of the robot really thinks it would bid 3C with 4 clubs and 6 spades, so there is very little chance it will take it out of 3SX. I, however, know the robot better in this situation. It would *never ever* bid 3C with this holding. In fact, I would dare say there is no holding whatsoever that this bidding sequence should ever happen. No player would ever bypass a 5 card spade suit at the 2 level, to bid a club suit at the 3 level.
