2018 Abu Dhabi Masters

[Richard Bates]

Maybe he was simply off colour or didnt sleep well - who knows?

I did suggest earlier that he didn't relish an important game early in the morning, and that still seems plausible. It is unforgivable to wreck the last round in this way.

Don’t really understand the argument that he was being irrational. Irrationality is opting for an outcome that results in no or minimal prize in favour of seeking an outcome that offers genuine financial benefits (although even then for some FIDE rating points are more important!). If by taking a draw he guaranteed himself a serious prize then his decision is determined by his risk appetite, not his capacity for rational decision making.

[Michael Farthing]

Irrationality is not even that. Irrationality is behaving in a way that detracts from a players personal objectives - which may not be financial at all. Thus, opting for a quick draw to avoid tension with your opponent who is your brother or to get an earlier train home are both rational choices if your friendship with your brother or getting to bed on time are more important to you than money.
