Thanks to merciful help of predecessor <SwitchingQuylthulg> who voluntary gave away a big lead.

Switchs sporting way of looking at things:

<I'd probably have stopped at 66K if not for <Chnebelgrind>, but with him gaining ground fast and badly wanting the top spot it just didn't feel safe up there. And I still think I made the right decision> (moronovich chessforum)

This are benchmarks which are to adjust in a given case.

Players younger than 20 usually are underrated, players over 45 tend to be overrated.

With Bilbao score, Sofia rules or other similar regulations the probability of a draw declines.

The probability also depends of the type of player, the tournament and the current state of a tournament.

In chessbookie game I set the sum that don't lower the value V of an invested buck under 1.1

V = product of the probability that a result will turn up and the projected payout

Normally I don't set more than one third of my funds.
