Excellent tool for chess learning – Chess Openings Pro Review

I use this app all the time and it delivers what it promises. If you are serious about chess, you will get your money’s worth in the paid version. One thing that would make for a better user experience would be some sort of buttons or gesture controls to parse through moves. (The SmallFish iOS app does this well—perhaps something similar to their setup would be doable.) It’s a little annoying to have to tap the tiny moves in the annotation bar under the board to advance through a line. My only real complaint is that positions that are reached with multiple move orders do not always show the same results. I recently noticed this while looking through a Sicilian line: if you enter 1.e4 c5 2.Nf3 Nc6 3.d4 Nxd4 4.Nxd4 cxd4 5.Qxd4, there is no data for the position, whereas the more common 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nxd4 5.Qxd4, with the pawn taking first and the knight taking second, displays several suggestions from the app’s database even though they transpose to the same position. I’m not sure if this is an intended feature, but it would be most helpful if this were not the case. It makes me wonder what other results aren’t showing up in positions that are commonly reached through several different move orders.
