I expected based on Antony that movei on A1000 will solve all of them in a short time but it does not do it. I implemented function to analyze epd and not leave a position before mate unless very long time was used and I test it with this function. The fact that there are a lot of easy problems does not mean that all of them are easy and solving all the positions on p233 in less than a minute(not one of them) is clearly a good result. Movei was not designed for finding mates and I disabled many extensions when the side to move has a big advantage but I do not think that by only changing parameters I can get all the positions in less than a minute.
