One chess parent told me he thought one of main benefits of having kids playing chess was the constant challenge to kids. The kids learn to deal with setbacks since they are in up and down all the time. I remember I heard more than once Abe told himself “I’d better win this one”, but he lost it; Abe murmured “How I could lose all the games”, but it was real. The same challenge also applies to parents. The parents are constantly embarrassed with the high expectations for their kids. Although that expectation might come from the love of your kids and the passion of you to the game, it’ll put too much pressure to the kids and it is not healthy.
As Abe’s rating jumps and dives, I know that there are apparent weaknesses in his game, it needs time and experience to fix them. For example, as more than one person mentioned, Abe needs improve his endgames. But if not slowing down and not playing with strong opponents, as i understand, you might not have any experience playing the endgame. Abe slowed down a lot recently, and I prefer him to play with strong opponents, even most games results in losses.
In the past several tournaments, I said “good job” to him after each of Abe’ loses, he slowed down, put a good fight and I was happy for him.
