Thank you Dr. Beco / Xadreco Chess Engine!

I've updated ethercalc.org/71jfmfuu762m

It has two additional questions:
- Which play against bots, computers and/or humans? (22a = bots, 22b = computers, 22c = humans)
- Which have a maximum amount of games they play at the same time? (23a = 1 game, 23b = 2 or 3 games, 23c = 4 to 10 games, 23d = more than 10 games)

updated ethercalc with UCIbot and Sugarbot

Thank you!

The difference between question 17 (simuls) and question 23 (maximum amount of games at the same time) is that simuls can be found at lichess.org/simul and unfortunately bots are currently not allowed to participate in them, but bots can play multiple (for example correspondence) games at the same time.
