In this case, I use Crafty.
Here is a game where the first part was actually played, but afterward Crafty is telling me off. So, I decide to get back at Crafty a little and keep playing, throwing in some of my own moves, but mostly using Crafty against Crafty. The result? After White being down nearly -3.00 for most of the game, White chips away at that notion and is eventually able to draw it. Once again, fortune favors the bold! BTW, the result is a draw, so it’s not the best move, but rather shows that there are practical chances in some games that are evaluated as if lost. In the actual game, I won because of an endgame blunder by my opponent.
I’m sure that Fritz would throw in some winning moves as Black, but who the heck is playing against Fritz? I think Crafty is 2300+.
I play out tons of these types of games with Crafty, either analyzing an opening or a game. Lest you think I spend oodles of time, I spent < half on hour on this. When I play Standard games on FICS now, my opponent is almost invariably in time-trouble and and I have scads of time. It may not be playing strength, but my playing speed has really shot up out of nowhere. I can blitz 1800+ players at Standard, I can blitz the blitzers at Standard.
For me, chess is mostly about mental energy rather than time. When I have it it’s like a car that goes for a long drive, but a few days later, at any time, it can suddenly run out of gas and takes a few days to get it back, maybe 4 days. The only problem with chess for me is that I should not be playing and spending my mental energy on chess because I am a programmer by trade and should be doing/learning more of that with my brain energy. If you do something less intellectual for a living, then chess is perfect to add that balance back to your life. But in practice I’d guess a lot of us already have other mental jobs and hobbies and thus overload ourselves.
I just made up another line that Crafty said was 0.0, but I thought there was something to it and it ends up winning by routine-play from Crafty.
