And interesing thing of note. When using the tactics trainer, although it doesn't do much in the way of explaining why or why not the moves you chose are good or bad or what the point of the correct moves are, if you click the analysis board, it will take you to a page where you will find a link to the source game that the tactic was based from. There, you can find the continuation of the game and see more of the point of the tactic itself and also use the analysis board to play around with the positions. Cool stuff :)
You can experiment on that board or play the computer with either color too. I usually do those thimngs. Thanks for the hint. I didn't realize.
Good to know. Thanks!
