Two part question

I want to start 4,000 games of chess.

Each batch of 500 games will be started on consecutive days.

I never want to timeout and want to play the minimum number of moves per day to avoid the risk of timeout.

I want to move as late as possible in each game, and saving my timebank as much as possible unless the average moves per day exceeds 1000. If timebank is utilised then it will be one day at a time in the game it is required in.

My opponent will always move as follows

3/3 or 3/7 games – the day after I move
7/7 or 7/14 games - two days after I move
14/14 or 21/7 games – four days after I move
21/14 or 21/28 games – 6 days after I move

The games will have the following time controls and be started in the following order

500 games with 3/3
500 games with 3/7
500 games with 7/7
500 games with 7/14
500 games with 14/14
500 games with 21/7
500 games with 21/14
500 games with 21/28

What is the minimum number of moves I must make each day for the first 30 days to avoid any possible timeouts?

Second part

Assuming each game lasts 40 moves in total (20 moves each), how long will it take to finish 1000 games?

I got 446 moves / day

EDIT: Should I assume you play the minimum number of moves in part 2?

Yes
10,001 moves per side per hour based on 0.003 seconds thought per move, divided by the square of the square that you moved from, times pie.

I came up with only 1820 good moves. Those would be the first two or three in each game. After that, they'd all be random.

zero moves

if you immediately join chessaholics anonymous and realize that you must never play another move of chess if you hope to lead a normal life. In which case, you never begin any of the games -- in which case, there'd be no timeouts to worry about. ðŸ˜€ðŸ˜€

Just take the average number of moves you need to make each day for each series (for example 500/4=125 for the 3 day time controls) which would lead to 425,93 moves a day, or integer solution 426.

17, but this is only a guesstimate. I work with a very high rate of error.
