The big result from the Quebec Open was from current Canadian Women's Champion WIM Maili-Jade Ouellet, who finished 5th behind the four GMs who won. Our Canadian Game of the Week is WIM Maili-Jade Oullete vs GM Alexandre Le Siege from the second-last round at the 2019 Quebec Open. In the diagram, White has an extra pawn and the move, so it is "just a matter of technique". But which technique?

an extra pawn which is also an outside protected passed pawn... "and the rest

conflicting maxims for every difficult decision.} 39. a5 $6 {3) "Time trouble
makes fools of us all." ? With perfect play, this doesn't give up the win. In
fact, at 30 ply this is Stockfish 10's second choice, +4.1 and almost as good
as its top pick (Re4) -- but it turns out to require much more precise play
than the R moves in the note below.} (39. Re2 $2 {4) "Rooks belong behind

advantages without committing. The white R keeps Black's R tied to the defence
of the b-pawn, and keeps the black K cut off from the queenside (White can
even go g4 to stop ...Kf5) long enough for White's K to get close to the
b-pawns, after which White can advance the a-pawn and (eventually) win Black's
